A knockdown rebuild in East Killara costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Ku-ring-gai Council approvals, and construction under one fixed-price contract.
East Killara KDR — Single Contract, New Home
East Killara punishes lazy engineering, which is exactly why a knockdown rebuild here needs a builder who reads the ground first. The suburb falls off the Killara ridge into the Lane Cove valley, and blocks of 800 to 1,500m² carry significant slope with reactive clay rated M-H on many lots. That combination, slope plus movement-prone soil, pushes piering, retaining and drainage costs above what the ridge-top Ku-ring-gai suburbs pay.
Ku-ring-gai Council reviews demolition and streetscape character closely, so allow time for a considered DA rather than banking on a fast approval. The upside is real: 1950s to 1980s housing stock with $2.8M to $4.2M medians, golf-course and bush outlooks, and land deep enough for a genuinely large home. Duplexes need 1,200m² here, so most projects are single premium builds.
What I would check first on an East Killara block: the slope and reactive-clay soil, the piering and retaining it drives, and the Ku-ring-gai DA timeline. Those set the budget.
We build these fixed-price, licence HBL 487805C. Have us assess the slope and soil before you commit to a design budget.

Slope plus clay punishes lazy engineering
East Killara falls off the Killara ridge into the Lane Cove valley, and blocks of 800 to 1,500m² carry significant slope with reactive clay rated M-H on many lots.
That combination pushes piering, retaining and drainage costs above what the ridge-top Ku-ring-gai suburbs pay, so a builder who reads the ground first is not optional here.

How It Works
From First Call to Final Key
Site visit covers everything that affects the build cost: vehicle access for trucks and crane, services (sewer depth, water connection, electrical service rating), soil exposure for borehole, neighbouring construction, and any obvious heritage or tree constraints. Real numbers, not estimates.
⏱Architectural design for your replacement home, structural engineering for Class M–H soil, BASIX certification, and all approval documentation. Lodged as CDC (10–15 days) or DA (40–90 days) depending on design.
⏱Demolition runs 5–10 working days for a standard East Killara cottage — longer if asbestos volume is significant or the structure includes a brick chimney or solid-block walls. Asbestos work happens first under a controlled removal program before mechanical demo starts.
⏱New home built from engineered slab (Class M–H soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original East Killara block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule. Move in.
