A home extension in Kirribilli is about the most demanding version of this work there is. The homes are 1880s to 1940s heritage on 200 to 500m² blocks right under the Bridge, on some of the most valuable residential land in the country — so the addition is designed to the centimetre, and the conservation controls lead every decision.
The oldest fabric carries lead and asbestos, both handled as licensed processes, and on the attached stock the party walls are assessed before anything ties into them. Harbour glimpses are captured wherever the envelope allows, because on land this valuable a sightline is worth real money.
At a $3.5M to $8.0M-plus median, the only kind of addition the market rewards is an exact one — there is no room, literally or figuratively, for anything loose.

Precision under the Bridge
Kirribilli's 200 to 500m² blocks demand the addition be designed to the centimetre — light, levels and harbour glimpses worked within the conservation envelope, on some of the country's most valuable residential land.
The postcard setting rewards exactness and punishes everything else.
Oldest fabric, exact process
The 1880s-onward fabric carries lead and asbestos, handled as licensed processes both.
Party walls are assessed on the attached stock before anything ties in, and all of it is priced into the job from the outset.
