It is accepted architectural practice to provide a clear distinction between the new and the old when extending a house with heritage features neither volume pretends to be something it's not.
But it is possible to integrate the disparate elements with subtle visual links, as this project demonstrates.
Architect Debra Brown of Hofman and Brown Architects was commissioned to design a contemporary, light-filled addition to the 1900s Edwardian home owned by her sister and brother-in-law, Jennifer and Jaimie Ratten. Not surprisingly, the renovation was constrained by stringent regulations designed to preserve the heritage feel of the neighbourhood. The addition could not be too obvious from the street, and the second storey could only occupy a small area in the centre third of the block.
Brown says she wanted to give the old house breathing space, and consequently designed a small, flat-roofed linking element to join the existing house to a modern, box-like volume at the rear.
"Various additions had been made over the years, including a skillion lean-to at the back," says Brown.
"These were removed, and the old house was repainted and the brickwork re-tuckpointed. Essentially, the original part of the house has become the parents' retreat, while the addition houses the new family living area and kitchen, with a children's living area and bedrooms on the upper level."
