New Home on Your South Turramurra Block
A knockdown rebuild in South Turramurra is a premium project with a valley twist — this pocket sits in the Lane Cove River valley, so the blocks are steeper and the soil more reactive than its ridge-top sibling suburbs. On 800 to 1,500m² blocks holding 1920s to 1960s stock, a rebuild delivers a substantial family home, but the ground design does more of the work here.
The soil grades Class H to E where the valley deepens, so an engineered slab and retaining design add cost compared with ridge-top Turramurra. I get a real geotech and design the substructure and retaining for the actual slope and soil, because on a reactive valley block that is where the budget lives.
The pre-war heritage stock almost always carries asbestos and can carry lead paint, so a licensed strip-out leads the demolition. There is no station of its own here — it is quiet, cul-de-sac, family-oriented.

A valley, not a ridge
South Turramurra sits in the Lane Cove River valley, with Browns Field and Browns Forest reserve framing the southern edge. The blocks are steeper and the soil more reactive than ridge-top Turramurra, so a rebuild here is as much about the ground as the home.
On 800 to 1,500m² cul-de-sac blocks, it is a quiet, family-oriented pocket where a substantial custom home fits well.
Reactive clay and retaining drive the cost
The soil grades Class H to E where the valley deepens, so the engineered slab and the retaining design add cost compared with the ridge. I get a real geotech and design the substructure and retaining for the actual slope and soil, because that is where a valley-block budget goes.
The pre-war stock almost always carries asbestos and can carry lead paint, so a licensed strip-out leads the demolition.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your South Turramurra block — lot size (typical 800–1,500m²), R2 Low Density zoning, setbacks, FSR, and existing dwelling condition. Asbestos survey included. You'll know feasibility and budget before committing. Complete design package: floor plans, elevations, 3D renders, structural engineering, geotech, BASIX, stormwater, and all documentation Ku-ring-gai Council requires. Approval managed start to finish.
⏱The South Turramurra construction phase. Fixed price, programmed, supervised. Pre-demolition: dilapidation report on adjoining properties (protects you against unfounded damage claims), service disconnections, asbestos clearance, neighbour notification. Then 1–2 weeks of physical demolition with material sorted at site for recycling where possible. Fixed-price construction: engineered slab, frame, lock-up, fit-out, external works. 8–12 months depending on size. Weekly progress reports with photos and milestone tracking.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Same address, completely different home. Permanent gas, water, electrical, NBN reconnected and tested. Council waste collection re-registered. Mailbox reinstalled. Move-in ready, not move-in plus 100 small jobs.
⏱Quality Promise
South Turramurra knockdown rebuild done cleanly: licensed demolition, compliant slab, new home built to NCC 2025. Fixed-price contract.
