There is a strong appreciation of our heritage suburbs today, but this wasn't always the case. Back in the '50s, for example, local authorities allowed a red brick-and-tile pitched-roof house to be built right in the centre of Castlecrag, Sydney a heritage suburb designed in the 1920s by renowned Canberra city architect Walter Burley Griffin.
With the older properties having flat roofs and a sandstone construction, the '50s house was a serious incongruity, says Joseph Alliker of Rudolfsson Alliker Associates Architects, the architect responsible for the design of a new home to replace the red brick house on the site.
"The original homes sit on curved, radiating streets that appear carved out of the local rock. They are relatively small, mainly single-storey houses on large blocks given over to greenery, with gardens running into one another, and shared areas of parkland. The houses on either side of this one were the original display homes, and were considered quite radical for the time."
Not surprisingly, there were strict covenants in place for the new build, not only in terms of the aesthetics, but also in respect of retaining neighbour's views and privacy, and various setback requirements.
"It was logical to extend the house into the garden," says Alliker. "This determined the idea of the glass living pavilion, which pushes out to maximise the northern aspect. The bulk of the house remains in the same position as the original. We also decided to put the carport at the front, as another low, flat-roofed extension, which relates to the scale of the neighbouring properties. Walter Burley Griffin was adamant that all the houses in the development would have flat roofs."
