A knockdown rebuild in Curl Curl costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Northern Beaches Council approvals, and construction under one fixed-price contract.
Knockdown Rebuild Builder in Curl Curl
A knockdown rebuild in Curl Curl is a premium oceanfront project — Federation beach houses, inter-war heritage and post-war brick on 450 to 800m² blocks. The oceanfront premium is genuine, and a rebuild designs a modern coastal home around the beach.
The coastal stack applies: the Coastal Hazard zone on direct beachfront, coastal acid sulphate soils (CASS) on the Curl Curl Lagoon-edge lots needing a managed excavation approach, salt-grade specs, sandstone rock priced from a geotech bore, and the Heritage Conservation Area on the older streets.
The pre-war stock carries asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the coastal stack costed, before you commit.
Buildana manages the complete knockdown rebuild process in Curl Curl — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Premium oceanfront, full coastal stack
Curl Curl's oceanfront premium is genuine, on 450 to 800m² blocks of Federation-to-post-war stock. The coastal stack applies in full: Coastal Hazard on the beachfront, CASS on the lagoon-edge lots, salt-grade specs, and heritage on the older streets.
A rebuild designs a modern coastal home that lasts in the environment.
CASS and the lagoon edge
The Curl Curl Lagoon coastal acid sulphate soils need a managed excavation approach on the lagoon-edge lots — disturbed acid sulphate soil is a real environmental and cost issue if unplanned, so I test and plan for it upfront.
The sandstone rock is priced from a geotech bore, and the pre-war stock's asbestos and lead paint are handled with a licensed strip-out.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Curl Curl homes from the 1920s–1960s heritage + premium contemporary — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class Hawkesbury Sandstone soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Curl Curl block you'd get on a greenfield build. The only difference is you still live in the street you chose.
⏱Quality Promise
Curl Curl KDR projects run on one contract: demolition, asbestos clearance, approvals, construction, handover. One builder accountable.
