Being green and sustainable is such a trend thing at the moment. Everyone and every company or product claims to be sustainable or green.

But how do you know if they are really interested in making a change. Or if they really care about the environment and have knowledge about sustainable and energy efficient construction?
If you start having constructions with a potential builder for your renovation, extension or new build, here are 3 questions you should ask before making a decision on who to engage. ow.ly/rvdT30giFPm

Here comes another 3D image from our 2 unit project in Eltham. The highly energy efficient homes will be build using SIPS (structural insulated panels) by Fenster & Panel we are currently working on the construction drawings and are hoping to start construction early next year. Although the 2 homes will use the same construction materials, they will look completely different. Unit one is a more traditional style home, with wearherboards and a gables roof, including a roofed verandah. Whereas the second home will have a much more modern appearance. With feature timber cladding, dark grey metal cladding, a green roof on the garage and a sleek single pitch roof. ... See MoreSee Less

In Australia, energy rating assessments are done pre-construction, assuming competent application of all insulation and building materials as well as draught sealing all wall penetrations.
In Europe, energy efficiency is most often assessed or checked post construction, with special attention to the prevention of thermal bridges. Some countries require airtight buildings, and amongst other things, double glazing, solar energy for hot water and heating systems, the usage of storm water, greywater recycling, recycled materials and product life cycle considerations to minimise energy demand and carbon footprint.

The Passive House Standard is also a way that looks at the actual building, rather than just a theoretical assessment.
If you want to know more about how to make your home more energy efficient or if you are interested in the passive house standard please don't hesitate to contact me. Would love to tell you more all about it

The upper level cladding has been installed. The brick boundary wall is in. The new cross over has been poured. And down pipes and gutters are in. All ready now for the installation of the insulation. When installing insulation make sure you have someone who knows what they are doing. Sadly even a lot of insulation installers have not a glue at all and insulation is installed with gaps everywhere. We are using the crew from Eco Mad, to make sure the insulation is installed correctly🏠#constructionupdate 🏠 ... See MoreSee Less

Here comes another 3D rendering from our 2 unit development in Eltham. We are building two highly energy efficient residences, using SIPS (Structural insulated panels) for the walls and the roof. We’re currently working on the construction drawings. So hopefully construction will start early in the new year. #sips #buildingforthefuture ... See MoreSee Less

I often get asked why all our homes look so different. Or what our style is.
Well, the answer is quite simple. We do specialise on energy efficient and sustainable homes, not a certain design style or look.

The things that define a sustainable and energy efficient home don’t have much to do with the look of the house. The main thing is that the house needs to be well insulated. You need high performing windows. Thermal bridges and air-leakage need to be minimised. Ideally the house should have some thermal mass. And you should have good solar access. These are the main things. What kind of roof form you have, or what cladding or wall finish you use is up to your personal taste. #designflexibility #buildingforthefuture

Do all sustainable homes need to look the same?

What does define a sustainable and energy efficient home? Do they all have to have the same features, in order to be energy efficient? The simple answer is: NO, not at all. No matter if you are building a French provincial home, a period home or an ultra-modern home. The actual look of the house does not define its energy efficiency #buildingforthefuture #designflexibility ow.ly/BTqD30gdmA5

Here a 3d image of our small renovation project in Carlton North. We are doing energy efficiency upgrades and quite some repairs to this heritage home. We had to apply for a town planning permit, due to changes to the roof, slight changes to some windows and the addition of solar panels. We are currently waiting on the planning permit. Hopefully not long now. ... See MoreSee Less
