About this home

The back half of our single frontage weatherboard house was substantially renovated in 2006, creating extra bedrooms & bathrooms when adding a new living/dining/kitchen area at the rear and a second floor.

After 2.5 years of back and forth due to the heritage overlay, we managed to obtain a planning application for the renovation of the front half of the house in 2019. As no external alterations were approved, the only way to create additional kids bedrooms was to go down instead of up.

We are very proud of our now fully renovated home as it still looks like a standard single frontage weatherboard house but the inside is completely transformed into a very comfortable space for two adults and two teenagers.

Being the founder of TCK Solar and managing it for 17 years meant of course, that going all-electric at the same time was none negotiable. We are now generating more energy than we consume and are enjoying negative power bills all year round and of course are no longer connected to mains gas.

Every possible improvement TCK Solar is offering has been integrated into our home, from solar, battery, hot water heat pump, through 3-phase upgrade, hydronic heat pump, induction cooktop to aircons, EV charger, rainwater tank, insulation, LED lighting, retrofitting double glazing, etc.

We are very much looking forward to welcoming you to our home to show you how all these technologies can work in harmony without sacrificing comfort and impacting the environment.

Q & A

What motivated you to build or retrofit sustainably?
Protecting the environment has played a key role in my life since my teenage years and has influenced all my decisions since then from becoming an industrial engineer, moving to Australia and founding TCK Solar in 2009.
Disconnecting from gas, upgrading to 3-phase and installing solar & batteries. We are enjoying our fairly high-tech home a lot within a great community, especially as we are not impacting the environment and have no running costs apart from small water bills.
Given that I've been promoting all-electric energy solutions for over 10 years and have performed CPD trainings sessions for about 1,000 architects during that time, I can't think of an aspect I've missed in my recent renovation.
I am lucky of usually being the guinea pig for new products TCK Solar is testing so that I haven't got anything on my list I want to change at the moment.
