House Notes – Hutt 01
We are architects and designers, specialising on sustainable homes. We finally had an opportunity to build our very first own home, and we went full steam ahead. The house has not only been showcased on Grand Designs Australia, but it is also designed to be a ShowCase home in itself : We love the idea of net zero energy homes, and we are always trying to convince everyone that that is the way into the future, so this was a great opportunity to show one. The home is a passive house with lots and lots of experimental and exciting features, from the eco garden aquaponics system via CLT structure and passive house technology to a green roof and an (almost) off-the-grid-electricity system with Solar PV and batteries. So exciting !
