A home extension in Coogee is a straightforward call once you run the numbers: trading out of a 250 to 600m² foothold a walk from the sand costs far more than the addition that fixes the house you already own. So you hold the beach position and build into it.
The work goes up for the ocean where the controls allow, and backwards with courtyard discipline where the block has the depth — always in salt-grade materials, because the beach air is merciless, and always with the conservation frontages kept. The pre-war fabric carries lead and asbestos, both handled under licence.
At a $2.8M to $6M median, an engineered upper level that claims the ocean is the single most valuable room you can build here — and the beach-village life below it carries on unchanged.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the view potential assessed, before you commit.

The foothold wins
Coogee's beach premium makes the foothold worth more held than traded, and the addition grows it — engineered upper levels for the ocean, rear reworks where the courtyard has depth.
The beach-village life stays put while the house transforms around it.
Salt and fabric handled
Salt-grade materials are standard near the sand, not an optional upgrade.
Licensed handling covers the pre-war fabric, and all of it is priced into the job from the outset.
