Background and Brief

This project is being completed by owner builders and it has taken a while to build.  Expected completion 2022.  It is an Enerphit project.  An existing small brick veneer had a pavilion added to the rear than also extended over the existing house.  The existing house was extensively gutted & re built; the bricks were taken down & recycled, additional framing added & it was re-clad in Weathertex to match the new pavilion (with some Colorbond).

The owners wanted to convert a small old brick veneer into a modern home with 4 bedrooms & a second small living area for the kids, & a home office.  They wanted it to be efficient & sustainable.  Originally it was designed solar-passive, however during the design process this was changed to PH.

Challenges

This was an enerphit – old 80s brick veneer that was significantly altered and extended. The new part of the extension went smoother than expected; modifying the old building did not!
