Owner Builders and Sustainability

Following on from my recent post about Owner Builders and the importance of considering solar power, I thought I would throw a few more ideas to consider in respect to sustainability.
Owner Builders need to consider two specific areas of sustainability and conservation, one when they are building their project, and in the design phase.

Design considerations will including how you position your dwelling on the block to capture breezes or to make the most of other site characteristics to minimise your energy footprint.

Double glazed windows are great for reducing energy loss in the house and owner builders will also benefit from the acoustic benefits they bring. I am living in an apartment Monday to Friday on a busy Melbourne suburb with traffic and trams at the front door.

There is a rooftop bar across the road, and without the double glazing, the unit would be impossible to live in.
Consider the size of your eaves, in Queensland of course the wider the better to shade the house and minimise the impact of the harsh Northern sun, certainly not as necessary in Victoria.

The installation of water tanks is of course a huge benefit to the owner builder in terms of the money they can save on water rates with them rising year on year. Also, it is extremely important to the environment, and water will likely become a, more and more scarce commodity in the coming years.

It is interesting that councils have done a 360 degree loop on water tanks in residential suburbs and go from banning to mandating through the inevitable cycle.

During the construction phase you can look at water saving initiatives and encourage all your contractors to minimise waste. Use recyclable products, refuse single use plastics on site, do simple things like encourage keep cups and discourage bottled waters.

Owner builders need to be considerate of their local environment and other residents that may be affected by the works that are being undertaken.

They are all little things but they all add up and they all make sense.

I am not a greenie by any stretch of the imagination, but everything I have mentioned in this post can be done quite easily and I do believe that every little bit will help.

Happy Owner Building,

Rick

We have no council facilities where we are about to start building. So have been researching waste sytem plants & water tanks. We were hoping to use the gravity feed to avoid pumps & power but have been unable to use that option due to our soil test result. We live in a fire zone & were impacted greatly during the last fire season.

Double glazing is the norm in Europe but in Australia it seems to be considered a boutique option with commensurate costs. I am in a cold climate area and past experience has shown that aluminium frames for double glazing is yet another cheapo Aussie product, the problem being that the frames lose heat so badly that condensation runs off them. The solution is frames with a thermal break but where do I source windows with that feature. All contributions are welcome.

Hi, there used to be a company called Schuster Windows that made europian style windows and doors

Crosby Cook

Dear Steven,
Yes, you are right about the costs of double glazing. I would like to install triple glazing except that it costs too much. I live in the Central West of NSW where it gets both hot and cold, so double glazing is worthwhile. I put in a couple of aluminium, double glazed windows then discovered to my dismay that the amount of condensation on the frames is considerable. I discounted vinyl frames at the time because of their appearance, but for my next project I will use them. A friend sourced a supplier in Sydney whom you might like to contact. They supply uPVC double glazed windows and doors: Prestige Plus 1300 679 465

Regards, Crosby

Timber is a great insulator between double glazed frames, and if it's a hardwood it can offer better fire resistance than uPVC and alloy frames. The only real issue is the nitrogen change inbetween the windows.
I'm looking at glass "inserts" that have a plastic separator, but lets you build a timber frame around the insert.

I have spent the past 20 years in the UK and coming back home, I realise that although double glazing isn't considered required due to our beautiful weather, I disagree. It can get very cold in winter when I feel the cold air coming up through the floor boards, equally I would also benefit from keeping the heat out in summer too!
Honestly if our homes were better insulated, we would not be sitting in our homes with jumpers and scarves on, in winter or spending a fortune to warm and cool down our homes throughout the year. Australian homes can definitely do with better insulation... save money and use less fuel to keep our homes comfortable. On the flip side - the UK could definitely use some fly screens!

Christina Chiu

Not just double glazing, but under-floor insulation makes a really big difference, if you have a raised timber floor.

Mitchell Cameron

Hi,
Thanks Rick,
Yes we lived in the Southern Highlands for a while and double glazing became essential. Undertile heating was also great in winter. Chris

Hi Rick, interesting topic. Our site will require us to be off grid as no services reach us. I like to get your view on hot water. Typically in the area LGP gas is used for both cooking as well as hot water. Would you recommend to go solar - maybe with gas boost?
In winter we have upto -8degrees and I wonder if these rooftop systems are reliable under such conditions?

Hi Gilbert
I am currently living in this situation and found our solar hot water system a good investment financially and environmentally even though we do have to supplement supply during winter months due to limited sunshine hours.

Andrew Smith

25/8/2020 21:15:20

Hi All
We had a solar hot water system on our previous house, it lasted nearly 20 years and was trouble free and saved us a lot including the extra initial cost, it was a "Solarhart" system.
Defiantly put one on our new house.

Lynette McVicar

7/3/2021 08:30:13

Hi Gilbert,

Great to hear solar s working for you. I will add it to my BASIX statement. Hopefully we will have more sunshine in winter.

Neil Smart

29/9/2019 13:56:36

our solar system gave us good returns, paid for itself and some, within a few years, but after about 5 years before we noticed a reduction in the returns due to cracks in the solar panels, they are now useless, the joys of getting panels from the lowest bidder.

Kristen Garratt

4/12/2019 11:37:02

Hi Neil,

Interesting comment there. I've also wanted to put solar on my current house, but hearing stories on panel longevity is making me unable to commit. Many panels are made in low quality Chinese factories, and are sold by both low and high price companies.

How would you be able to tell the panel quality difference between a cheap and mid/high priced installer? Another issue is that many installers offer a long warranty / lifetime warranty, but this waranty is useless if the business is no longer operating after a few years.

I guess we need to weigh up both price for panels, but also the company size, reputation and previous installs to make the best judgement on who to go with.... i'm still not there yet in my decision making, but know i'll need to one day!

Luke Murphy

20/8/2020 17:37:53

We have had auxiliary solar for 12 years and while there is nothing wrong with our system as the market trend increases in size energy providers re-nig on their offer per kw/h.
Try to future proof with more kw is my only suggestion. :)

Christian

7/5/2021 12:06:44

I would suggest that you make sure you buy from a reputable company that has been around for a while and I do not think you would have a problem with warranty as most panels are offering up to 15 year warranty, even the cheaper ones.
We do not use a lot of electricity and installed a cheap 6.6Kw system, we are in credit during the summer and then use some of the credit up in winter. On a contract with AGL for 2 years getting 21c for feed in to the grid per KW. It has paid for itself within 2 years.

We have been using Trina solar panels for 15 years with no issues, definitely worth looking into and investing in the upgrade!

Gilbert

16/10/2019 12:02:41

We plan to have double glazing in our windows and doors. Does anyone know about the pros and cons to get glass which has a reflective shading applied to the outside. Will this increase the performance of the windows?
cheers

Hamza ALameddine

7/7/2020 17:13:36

I am in the same position, I would assume so, but would like to know if anyone out there has an answer.

Esra Biyik

28/2/2024 06:30:13

Hi, I have some experience with reflective shading/tint on double glazed windows, here are my thoughts:

Pros:
- Privacy
- Heat reduction
- Glare reduction
- Thermal efficiency

Cons
- Reduced sunlight in the winter/darker months
- Prone to sun damage that may require regular replacements

Rick. I do not believe that sufficient thought has been put into the installation of water tanks into private homes. The running and maintaining cost of the pump and diverter equipment out weighs the saving in water cost, especially with the cost of todays power. Water quality is also a problem as many councils require W.C.s and laundries to be connected to this tank water, which is usually heavily contaminated , staining both the toilet bowl and white clothing, requiring the use of harsh chemicals. I believe the better option is a simple free standing tank only supplied from the roof, with one hose tap to fill a simple watering can by gravity, for use in the garden or washing cars. There by making 100% cost saving on water from the tank.

Kristen Garratt

4/12/2019 11:30:35

Hi Mark,

I live in a newer house, that has this type of rain water tank connected. All roof rainwater is collected through charged downpipes to the rainwater tank, and is connected to one tap in the back of the house. This tap is pressurised, and is encouraged for use for the garden, washing cars etc. The tank itself is fairly closed, and never had an issue with water quality from this system.
I think you'll find this style of rainwater collection is becoming the norm, especially in newer development areas.

Quentin Mitchell

25/6/2021 09:24:28

I agree Mark and Kristen, I want to catch rain water and store in tanks under my deck for garden use, washing the car, outside use.
I will put an electric pressure pump on it, with solar power installed won't cost me much. May reduce some of my water bills, the sewer connection fee is the expensive part for me here in Albury.

Esra Biyik

28/2/2024 06:32:22

We had this exact issue and im glad im not the only one. The rain water tank has been heavily staining the toilet bowls. I believe having the water tank be used for gardening/washing cars is a much smarter and more efficient use of rain water! Interesting to see if there are other means out there to eradicate this issue safely!

Kristen Garratt

4/12/2019 11:33:26

nice read Rick.

One other consideration to the environmental issues raised in your post, is the economic factors associated with these improvements. Like you, i'm not a hard and fast greenie, but as the society moves towards sustainability and environmental considerations, some of the projects actually do provide some form of return of investment. For example, double glazed windows reduce noise, but they also minimise heat loss which in turn saves aircon running time and ultimately electricity use and $$$$ saved.

The use of concrete is a major contributor to greenhouse emissions
https://en.wikipedia.org/wiki/Environmental_impact_of_concrete

In addition, on surfaces, it contributes to faster water runoff which is a major contributor to water problems (flooding, hydro carbon pollution, micro plastics)

Hi Rick,
Thanks for the interesting read. Very true what you say as waste is becoming a huge problem today with landfill overpowering our space. Hopefully we can all work together to minimise this.

Thomas Lavers

8/3/2020 10:16:23

Great read Rick, you have provided some useful information to consider for my new build. As per our basix requirements we are already including water tanks, however will look further into solar options so I can make my build more sustainable.
Thanks again, Tom

As a definite greenie, this is something that has been of consideration at all stages of my project design.
One thing we are doing is using the surrounding landscape to our advantage. Sandstone that is being excavated from our site is being repurposed into a wall around our combustion stove to hold warmth in the house better. Also using trees with good cover in areas where we need shade etc.

I like the consideration of single use plastics on site. Providing subcontractors with a little kitchenette to encourage less wastage is a good idea.

Hi Rick,

I have been reading up a bit about the use of "green -Geopolymer Concrete" lately. It seems it could be an actual viable alternative to the wholesale use of concrete in the construction industry, both Commercial & Residential. However, Cost variances, Availability & Longevity are just some issues to consider . Like anything new, teething problems will exist, but just need to be worked through as they arrive. (Water tanks, solar panels etc are perfect examples)
Do you have any experience with the product & if so any thoughts..?

Andrew.

I believe the future should be houses that are as self sufficent as possible, this for me would be collect and filter your own drinking water. Solar power for your electricity and battery pack. you can even treat your own sewer and use the treated sewer to fertiliser your garden.

Johnny Wright

2/6/2020 21:22:36

Come to my world Joe. We Will have a 120 000L water tank, a septic and at least 6 kw solar.Cant wait for all this to happen!

Colin Hill

19/5/2020 08:43:17

I agree with the idea that one size does not fit all. The key is for your design to maximise what your house and property has to offer and to design out any negative influences such as the noise issue mentioned above. Personally, my new home will have an extremely high ratio of outdoor living area compared to inside as I am on private acreage and this is where we intend to spend a lot of our time.

Justin Larymore

20/5/2020 16:20:47

I like the idea of no single use plastic and will happily provide a jug of water for any trades on site.
We would love a water tank on site, but will have to wait and see re affordability.

Adam Marwood Cole

Good read but also remember the double glazed windows are not only good for noise reduction but for retaining heat in buildings that are in the cooler climates.

Since installing solar panels we've found our daily habits have changed. Whatever can be done during the daylight hours is done to take advantage of free power.

Hi Everyone
Just completed the course and happy with the end result.
About to start building our own home and woulkd like to know if anyone has had any experience with heated floors, we were thinking of electrically heated rahter tha liquid heated as our architect has heard that the liquid ones can crack the concrete due to the relatively rapid fluctuations in temperature.
Anyone got any ideas?

Hi Rick and everyone,

I am part way through the course right now and am completing it because we own a home that our daughter lives in.

We are planning g on extending to give her and her two children some extra space.

I must admit I was not looking forward it as this is not my field but the learning materials are making it more interesting, which I find weird as this is definitely not my field of work normally.

Thanks for the work you put into the courses for us :)

Great tips! We will be installing a Bradford solar unit, however, still reluctant to purchase batteries at this stage although the tech is getting better and they are becoming more cost effective from a ROI perspective. We will leave provision during the solar install for batteries to be a "plug and play" option down the track.

Hi Peter
Your architect's software should be able to show you the angles of the sun penetration in all seasons according to eaves depth. I am in north west NSW where this is an important consideration. We need winter sun and no summer sun. This can be achieved with careful planning.

As the owner builder, do I need to find the building inspector to do a report on asbestos before I know down the house?
Do I provide the SWMS or the contractor provides it

Clare Gleeson

2/3/2021 20:49:57

Zhu,

I would say it is often best to complete this yourself and issue to the demolition contractor so that you get accurate pricing and also to ensure the successful contractor is informed of these materials and undertakes the demolition in strict accordance with WHS requirements for removal.

Christine

This was a great read.
I am in the process of planning the construction of our new home and am very keen on water tanks.
I am all for tanks connected to roof pipes but not sure how effective this would be in times of drought. I would love for there to be a way of collecting the water from the "rinse cycle" from our washing machine. During the harsh months of fires during our devastating Black Summer in 2019-2020, we collected buckets of water from our showers and used them to flush our toilets. I connected pipes to the washing machine and directed the "rinse cycle" water to our garden, and though I do not have a dish washer I will only assume that the "rinse cycle" water could be used effectively to flush our toilets.
Not sure how this could be setup but keen to hear any ideas.

Jason Roberts

22/4/2021 11:04:52

Thanks Rick, an informative article. We as homeowners and caretakes of the environment should always consider the most environmentally friendly, sustainable and least impactful way to build. These decisions not only have an impact on the way we live within the dwelling of our choosing but also how that impacts on the local neighbourhood and the wider natural spaces in which we share with flora and fauna. We have to be responsible as owner builders, and the product and technology is out there for all of us to be able to make good material and design choices whether it is required or not.

Hi, I totally agree with larger eaves, the last house I built I installed 900mm eave, in summer with shading from the eave kept the house a lot cooler. I can't believe all the house in new suburbs have no eaves at all. Makes you wonder how they achieve BASX requirements hear in NSW. I do release it's all to do with building budgets and costs etc. Also I'm lucky enough to live on a large block, so this was achievable.

I truly believe that smart choices can help reduce the impact on our great planet as well as provide piece of mind to ones self, satisfaction and comfort in our home as well as being cost effective and energy saving.
In 2007, I embarked on a self build project. I had acreage that was surrounded by bushland, 10 acres in total (4 of which was clear to set the house, services and landscaping on). My brief was, I wanted a house that sat nicely in the surrounds and to be somewhat sustainable as well as having little impact on the environment as possible. I was also in a bushfire zone.
After plenty of research and attending a couple of workshops (with a company who does this kind of build), I settled for a straw bale home. Straw for me, ticked many boxes. Straw is essentially a waste product that contains superb insulating qualities (both thermal and noise). The clay for the earthen render came from my property which was generated when excavating for the slab. Once this kind of building is rendered, it becomes ten times more fire resistant than a brick veneer home. Tick. The majority of the materials that I used in this build were re use or recycled. Obviously new materials were also used where necessary. With thick, naturally well insulated walls and double glazed windows, the dwelling was exceptionally energy efficient.

Barry Robinson

The rules for sustainability seem to be always changing. A few years ago you couldn't put in rain water tanks in Dubbo, now they are a must to meet the BASIX.

Hi Rick

Very interesting read along with the comments from other owner builders. Being a carpenter i'm always looking at different designs and products to use but as most are aware cost comes down to the reason most people stick with the tried and true and don't look or haven't been informed of other products out there.

Interesting read...I installed double glazing in my last home and source the double glazed window panels directly from a company call DIY double glazing in Melbourne. http://www.diydoubleglaze.com.au Saved thousands and got a great result. Difficult to quantify exactly but I'd estimate a 5-7% reduction in our heating costs over winter.

Just wanted to build on this earlier post. We also noticed that we weren't running our aircon during the summer as much. Once again very difficult to quantify the exact impact and cost saving attributable to the double glazing as we also had 3.2KW of solar intsalled a couple of years earlier. During hot days I suspect the solar was producing enough power to drive the AIrCon and we did notice that the amount of power exported to the grid decreased. Our local power supplier only paid 6cent per KW, a watch out for anyone considering installing new solar, so the financial savings were minimal. Either way, the house felt cooler and held it's temperature better over night.

Don't forget to maintain your water tanks. Many houses have water tanks... way fewer have water tanks that are actually delivering the benefits after 5 years.

Rick
The place I live at was built in about 1920. It has 3.6m ceiling height. It originally had a tankstand at the back with squat tanks (about 760mm high) so that the tank top was just below gutter level which meant the bottom of the tank was still about 2.4 m above floor height. Thus all the house was fed by gravity with no pumps required.

Hi Rick,
Im using this coarse to get permission from the local council to allow me to erect one of those kit farm sheds. Ill probably only use 2 trades,a concretor and shed erector. Im too old to do the assembly myself but I want to keep my eye on how its going.
Thanks,

Hi Rick, Just a comment on water savings, Im looking to increase min water tank size for small granny flat, I to hopefully reduce water cost and be more environmentally friendly. The cost of increasing your water tank size seems like a small up front cost and could be a real benefit long term.

Hi Rick,
Very interesting read. I'm doing the course so as to obtain my owner builder certificate for renovations and extensions that I am planning on doing to my house. I've already put solar onto the house and after much research finally chose an installer. A great website to visit regarding solar is 'Solar Quotes' by Finnn Peacock. Very knowledgable and informative site where you can do plenty of comparisons on the different parts of a solar system. I'm excited by the prospect of completing this course and being involved in the build process at my residence and I thank you for the assistance, guidance and knowledge that you have passed on through this course.
Again, thanks.

Very interesting read, Rick you made some very points there and do agree with them all. I personally encourage any person or owner builder these days building or extending any building to consider and incorporate these ideas into their building designs. I will definitely be including them in my building works. Incorporating environmental conscious ideas into today's building designs and low ecological footprint building design ideas are a more important thing then ever to consider and implement when building or extending new dwellings today due to more unprecedented climate change influences we face today.

I agree new builds and some renovations to existing properties should consider alternative power supplies and sustainability but not without due research to what fits each one. Sometimes you might think you’re saving the planet but are actually taking yourself closer to bankruptcy and not helping much at all.

Les Sherwood

21/7/2022 16:07:56

Agree with the introduction of solar panels when building a new dwelling. While the technology still has a long way to go we have to start somewhere and with periodical government incentives it is worthwhile.
The is still a long way to go with effective battery storage but I believe that will be advanced in the next couple of years.
We intend installing polished concrete floors with underfloor heating. The solar will be invaluable, especially during the winter months to assist with the heating of the slab and room space.

Hi Rick,
Great information and a lot to consider. You could have so much by doing some very simple things. I am currently doing some research about solar panels and when and why you need a battery. It's a really interesting process.

Thanks Rick for your post. I am building at an ecovillage in Narara just north of Sydney and we have many sustainable homes already built here. Your owner builders are very welcome to come and look at examples of passive solar design, solar panels, batteries, double glazing (uPVC, timer, aluminium thermal break and composite windows), water tanks, ventilation systems and use of many different materials (natural like straw and hemp, conventional and new technologies). Thanks for doing your bit to promote sustainable building. Megan

I am seeking to build in the near future and looking at use of sustainable building materials and researching construction techniques to reduce my carbon footprint. My son-in-law is a Civil Engineer and volunteers with Engineers Without Borders. His been involved in building community projects overseas and some of there energy saving techniques such as converting kitchen waste in to clean energy is very ingenious.

My build is on 5 acres with power available but no water. I have to have 20,000 litres per acre with 20,000 being available for the fire brigade and a gate opening for their access. I will have 60,000 in tanks and a 50,000 litre dam. Water sustainability is certainly an issue here especially after the drought years experienced here with the town running out of water.
We should all be able to access double glazed windows at a reasonable cost if all of those recycled bottles were made into windows.

Duncan Ong

Interesting read, Rick.
I am building an attached granny flat next to a busy walkway, As part of Basix requirements, the council requires us to install a water tank, we managed to position the tank between the walkway and dwelling to provide some degree of privacy.
I believe with a bit of thought and planing, one can always create a win win situation for all the parties concerned.

In our last owner build we have installed double glazed windows, good insulation, a water tank that is sent through toilets systems. We have also had the roof designed to be most proficient for solar panels when we eventually get them installed. We were waiting until energy was stored for night time use, but it doesn't seem to be happening in a hurry but we've realised there is still many ways we can use solar energy during the day anyway. We also use off cuts and left over building supplies, pallets etc in our garden as my wife loves to upcycle.
Thanks for your post. Always good to keep in mind.

Emma Hillebrand

Agree with Steven King. When livingin Switzerland double glaze was a given. The insulation was incredible. We have 3 water tanks as we are not connected to town water. We struggle with both drought and floods (getting in and getting rid of water!). We are considering installing another tank. Additionally, with the increase in electricity prices we have now found that the cost recovery on solar batteries now makes sense. We have invested and the reduction in electricity costs is exciting!! (Does that sound sad??!!!)

Chris Young

8/12/2022 19:43:39

Great information. Our basix stated we needed a 3500L tank, but we ultimately decided to install a 5000L. Best decision we made, we haven't run out of water yet.

Quite and interesting Rick.
Sustainability is something that I think a lot of people forget during the design and build stage. But I feel in the current climate it is a vital item to have on the agenda.

I find it fascinating that council did not allow residential water tanks initially. They are off great benefit, they reduce house water usage and great for maintaining a garden

This is a great read :)

going through all of these motions currently working with engineers, surveyors, council etc.
our council actually has a requirement that any modifications or alterations to a property you have to install adequate drainage, water systems and a minimum of 2500L water tank. Expensive upfront cost although will definitely add $$$$ to the pocket in the future or a great selling point!

I am not a builder of any means, i am an electrician but it is so fantastic and enjoyable learning all of these aspects that you would never ever think would be involved!!

Some interesting points of view for energy saving but as owner builder I guess we have the benefit of weighing up the different services and our choice for what we want from our homes, not what the builder gives us as an 'only' option.

Garrie Wooden link

6/7/2023 18:01:02

Good read Rick , like you said double glaze is a good option for sound and heating and cooling if you have the budget for it. I have gone for laminated glass helps a little in those areas and wont smash as easy as standard domestic glass.

Joann Slovinec

Your blog contains some really good points to consider. We are trying to create a more sustainable build and are also considering a green roof and hydronic heating. There are so many new and interesting technologies becoming available, but some are still quite expensive so it pays to also complete a cost benefit analysis.

Hi Rick

Great article and well worth consideration of incorporating energy efficiency and water saving measuresinto he design rather than adding them later.

I found the BASIX tool was very helpful with consideration of the above measures, as was talking with others who have recently undertaken small developments such as the one I'm about to embark on.

We are keen to have 13KWHs of solar installed on our shed once we complete building it. We have already thought ahead and had a 10 000ltr rain water tank installed under ground. We still wish we could have went bigger.

Kevin Chatterton

19/2/2024 16:24:18

We are building in Upper Lachlan Shire and have no utilise on site except power. Saying that we are going to install solar and batteries with the intent of being off grid at the end of our project.
I have already put in a 60KL water tank off the shed with a 90KL tank planned for catching rainwater off the house.
I have placed a 40KL tank at the top of the hill to gravity feed down to our garden and animal troughs. We plan on having a solar feed for that tank down the track.
Good comments on here.
We will probably need to look at under floor heating before we start the build too.....gets pretty cool in winter

Great post, Rick! I completely agree with your points on the importance of sustainability for owner builders. Incorporating design elements like double glazed windows and wider eaves can significantly reduce energy consumption. Additionally, water-saving initiatives and the use of recyclable products during construction are practical steps that benefit both the environment and the builder's budget. Thanks for sharing these valuable insights!

Hi Rick,
I was one of the pioneers in air leakage testing of buildings in Australia so being a scientist did quite a bit of research and analysis on all the data we collected. We also used thermal cameras to test for insulation efficacy and coverage. It was during the time when the govt were subsidising ceiling insulation and some of the work was diabolical.
Anyhow, what we did find that was the majority of Australian housing and a good number of commercial buildings are extremely leaky so conditioned air (ie money) didn't stay contained in the building envelope for too long. The gear we had could quantify and qualify the leaks and there was a lot of simple remediation that could make a lot of difference to the running cost of a building. Unfortunately, back then getting leakage standards built into the building code was a little premature. Things have changed though it is definitely worth teaching owner builders about building envelope integrity and energy usage - after all its the same as buying a car and not knowing its fuel economy - just on a bigger scale. It also leads to better building life as water ingress / condensation is taken care of during the building phase.
Happy to provide more info to those who are interested.
Andrew
