A home extension in Wollstonecraft costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, North Sydney Council approvals, and construction under one fixed-price contract.
Extending Homes in Wollstonecraft
A home extension in Wollstonecraft is quiet-premium work. The Federation and Bungalow homes on 400 to 700m² blocks sit in a pocket that trades on understatement rather than show, so the wing goes in behind the conserved frontage and opens to the garden — adding the space without disturbing the leafy calm that is the whole appeal.
The Shirley Road precinct heritage area is checked before design, and where the western streets drop toward Gore Cove the fall is engineered rather than assumed. Pre-war fabric has the lead and asbestos handled under licence throughout.
At a $2.8M to $4.5M median — softer than Mosman proper — a wing beats trading out of the pocket, and the T1 station and the walk to Crows Nest hold every metre you add.
We build these fixed-price, licence HBL 487805C. Get our extension scope, with the heritage position checked, before you commit.
Buildana manages the complete home extension process in Wollstonecraft — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Understated, done exactly
Wollstonecraft's quiet premium rewards a wing done to its standard — behind the conserved Federation frontage, opened to the garden, engineered on the falling western streets.
The T1 station and Crows Nest on foot hold every metre you add.
Heritage and fall handled
The Shirley Road HCA is checked before design so heritage leads the plan.
The Gore Cove fall is engineered where it applies, the pre-war hazards run as licensed processes, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
Walk through your Wollstonecraft home with our designer and structural engineer. We measure, photograph, and check the bones — footings, frame condition, roof structure. The cost estimate that follows is grounded in what we found, not a generic per-m² number.
⏱Our designer works with your existing home's layout — connecting new living areas to existing rooms, matching materials and roof pitch, and maximising natural light. You approve floor plans and 3D renders before we proceed.
⏱Most rear extensions in Wollstonecraft qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through North Sydney Council because of overshadowing and privacy assessments. We choose based on your design, not on what's easier to lodge.
⏱Extension built from new footings to completion — connecting structurally to your existing home. Class M soil design managed. Temporary weatherproofing maintains liveability where possible.
⏱Walk through the completed extension, confirm finishes, collect your OC. Six-year structural warranty covers all new work including the junction with your existing home. Maintenance guide provided.
