Episode 03: Are These the Most Sustainable Terrace Homes in Australia? | Fitzroy Carbon-Negative Heritage Restorations

Step inside one of Melbourne’s most ambitious heritage transformations - two 150 year old terrace homes in Fitzroy that may just be the most sustainable terrace homes in Australia.In this episode, Simon Clark, builder and founder of Sustainable Homes Melbourne, walks you through the restoration and transformation of these derelict heritage-listed homes into carbon-negative, high-performance dwellings. Designed by Robert Nichol & Sons Architects, these twin terraces combine old-world character with cutting-edge sustainability - delivering 7+ NatHERS stars, full electrification, Tesla Powerwalls, and whole-of-home energy assessments that prove they offset more carbon than they emit.Simon explains how his team blended traditional craftsmanship with modern building science - from low-carbon concrete and recycled messmate timbers to R4-rated walls, airtight membranes, UPVC double glazing, and heat-recovery ventilation systems that ensure long-term comfort and health.Whether you’re a designer, builder, or homeowner passionate about heritage restoration and sustainable living, this case study will inspire you to rethink what’s possible in Australia’s inner-city housing.Key topics:How two derelict 1874 terrace homes became carbon-negativeThe role of low-carbon concrete, recycled materials, and energy modellingAchieving 7+ NatHERS star ratings in heritage contextsWhat “whole-of-home” energy assessments reveal post-constructionLessons for anyone pursuing a sustainable renovation in MelbourneIf you'd like to know more, please reach out to Sustainable Homes Melbourne or call us on 1800 683 697.
