A second dwelling, a new garage and a strata subdivision on a large sloping block at Oyster Bay, lodged as a development application with Sutherland Shire Council.

The site. 1,107 m² under the Sutherland Shire LEP 2015, with an existing three-level house that stays and a fall across the block that decides where anything new can go. The question on a site like this is not whether a second dwelling fits but whether it fits without pushing the combined floor space or the landscaped area past their limits.

The design. The existing dwelling is retained in full — subfloor, lower ground, ground and first floors, 255 m² — and the new dwelling goes in as a two-level building of its own: rumpus, two bedrooms, ensuite and bath below; entry, living, dining, kitchen and the main bedroom above, opening to a balcony. A new 36 m² garage sits separately off the driveway. Combined gross floor area is 470.98 m² against a 553.55 m² cap — an FSR of 0.43:1 where 0.5:1 is allowed — and landscaped area lands at 44.43% against a 40% minimum. A strata subdivision separates the two dwellings.

The approval. Development application to Sutherland Shire Council.
