A home extension in Cammeray is usually a decision to go up. The blocks are tight — 300 to 550m² under Federation and mid-century homes — so sprawling out the back is rarely on the table, and the room tends to be found in a first floor rather than a rear wing. It is precision work, designed to the metre either way.
The early brick takes a first floor well once the walls are engineered for the load, and rear-and-up combinations work the tight footprints hardest — pushing the kitchen out a little while stacking bedrooms above. The pre-war brick carries lead paint and asbestos, both removed under licence.
At a $2.6M to $3.8M median, adding up beats trading out of the village's orbit — you keep the Military Road life and the walk to town, and simply build the house taller.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block — and your walls — will carry.
Buildana manages the complete home extension process in Cammeray — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Up, mostly — and precise
Cammeray's tight blocks rarely allow sprawl, so the play is up — a first floor on the engineered early brick, or a rear-and-up combination that pushes the kitchen out while adding bedrooms above.
The village orbit is exactly what building up preserves.
Fabric and walls handled
Lead paint and asbestos both go through the licensed pre-war processes, done properly.
The walls are engineered for the first-floor load before design is committed, and all of it is priced into the job from the outset.

How It Works
From First Call to Final Key
Walk through your Cammeray 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 Cammeray 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.
