About Eltham Treehouse

Located on a steep, previously vacant, lot in Eltham at one of the highest points in the township, the distant views to the north are what initially drew us to the site. Having only ever lived previously in cold/hot inner city terraces and a cold/hot 1970’s Merchant Builder house previously in Eltham we approached the project knowing that building the thermal envelope correctly was the first and main priority. The Carbonlite team were the perfect builders for the project and were in lock step with our goal of a Passivhaus. Now newly completed we look forward to a future of low to zero bills and a reduction of our families impact on the environment.

The envelope is highly insulated with triple glazed windows. The house is also airtight and has a central MVHR ventilation system with only minimal supplementary heating and cooling. With both of us being Architects this project has been a once in a lifetime opportunity to explore how we want to live as a family, to show our children how our built environment can reduce our impact on the planet all while doing it in a highly unique outcome.

You can also speak with homeowners directly on Saturday 19 September, online, as part of The Nillumbik Trail. Register here to participate.
