A home extension in Turramurra costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Ku-ring-gai Council approvals, and construction under one fixed-price contract.
Second-Storey & Rear Additions in Turramurra
A home extension in Turramurra is ridge-top heritage work. The homes are 1920s to 1960s on 700 to 1,100m² blocks, and the character out the front is the point — so it stays exactly as the street knows it, and the generous new living goes in behind where the heritage face never gives it away.
The blocks are a touch tighter than the Pymble estate lots, so the design works a little harder, but there is still real room. I check the heritage position before drawing, and the pre-war fabric has lead and asbestos cleared under licence. The finish is built to the premium standard the ridge expects.
At a $2.8M to $4.2M median, with the catchments holding families for the long term, extending is the natural move — you grow into the house rather than out of the school zone.
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 Turramurra — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Behind the ridge heritage
Turramurra's heritage streets extend the right way — conserved frontage kept, a generous modern wing behind, gardens retained on the 700 to 1,100m² blocks.
The catchments hold families for decades, so the wing is designed for that horizon rather than the next few years.
Heritage and fabric, sorted
The heritage position is checked before design, so the approval path is clear before money goes on drawings.
The lead paint and asbestos in the pre-war fabric come out under licence, all of it costed into the ridge-standard job upfront.

How It Works
From First Call to Final Key
Walk through your Turramurra 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 Turramurra qualify for CDC — cleaner, faster, no neighbour notification. Second-storey additions typically need DA through Ku-ring-gai 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.
⏱Quality Promise
Our Turramurra home extensions connect old-to-new cleanly. Matched brickwork, tied roofline, no awkward transitions.
