Background and Brief

This project is being completed by owner builders and it has taken a while to build.  Expected completion 2022.  It is a project targeting EnerPHit certification.  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

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