A difficult house alteration with a heritage component. The original building is an old colonial school house recently relocated to this small site in Avondale. The design brief was for major internal alterations and an upper level addition including 2 bedrooms and a bathroom. The development controls for the site meant the original building was at maximum building coverage, so it was not possible to increase building footprint without a resource consent application. In addition the development had to retain the essence of the original colonial school house.
