Cosgriff House in Sydney, Australia was envisioned by architect Christopher Polly as a modern dwelling, preserving its original envelope. The newly added extension opens up the residence towards the garden, adding more living space and more natural light. Building higher than the existing wall alignments, a third level was created on top, offering great views to the east.

The well planned structure of the extension offers easy access to new interiors and a practical overall design: “Utilities located deep within the semi-subterranean rear of the lower ground enable direct connection of the living space to the garden and jacaranda tree, while the re-worked ground floor above adds a bathroom, main bedroom and adaptable bedroom providing flexibility for future use as a study“. Vaulted ceilings and skylights allow natural light inside, making each room feel welcoming and enhancing particular color contrasts.
