A home extension in Point Piper sits at the very top of the Australian market, and the work is judged accordingly. These are grand heritage mansions on 600 to 2,500m² blocks, so the wing is conservation-grade, the harbour frontage is engineered with rock anchoring as standard practice, and nothing short of exact survives contact with the address.
The heritage areas lead every decision, the fall is engineered off a proper geotech rather than assumed, and the pre-war fabric gets licensed handling throughout. On blocks and values like these, the engineering is as much the project as the architecture.
At a $15M to $100M-plus median, the addition is built to an international standard or it is not built at all — there is simply no margin for a compromise.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with heritage, rock and fall resolved, before you commit.

No margin for less
At Point Piper's values the wing is conservation-grade or it is a mistake — restored fabric, additions to international standard, and the harbour frontage worked with engineering to match.
Rock anchoring on the fall is standard practice here, priced from the geotech.
Everything priced exactly
The heritage position, the fall, the rock and the pre-war fabric are all resolved and priced before design is committed — the honesty a project at this scale demands.
All of it sits in the scope from the outset, with nothing left to be discovered.
