Quick Answer
A knockdown rebuild in Cromer 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.
New Home on Your Cromer Block
A knockdown rebuild in Cromer is a practical Beaches play — 1960s to 1980s brick on 550 to 800m² blocks inland from the beaches, at more accessible prices than the coastal suburbs. The aging stock suits a modern family rebuild.
The sandstone means rock excavation is typical, priced from a real geotech bore. On the perimeter lots backing the Narrabeen Lagoon catchment, BAL-12.5 to BAL-29 bushfire ratings shape the design.
The older homes can carry asbestos, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility, with the rock and bushfire costed, before you commit.
Buildana manages the complete knockdown rebuild process in Cromer — 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.

The practical Beaches rebuild
Cromer offers the Northern Beaches at more accessible prices — 550 to 800m² blocks of aging 1960s-80s brick, inland from the beaches but close to everything. A rebuild resets a dated home into a modern family one.
It is a quiet suburb where the rebuild maths genuinely works.
Rock and catchment-edge bushfire
The sandstone means rock excavation is typical, priced from a real geotech bore. On the perimeter lots backing the Narrabeen Lagoon catchment, BAL-12.5 to BAL-29 ratings shape the design.
The older homes can carry asbestos, so a licensed strip-out leads the demolition.

How It Works
From First Call to Final Key
We assess your Cromer block — lot size (typical 550–800m²), R2 Low 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 Northern Beaches Council requires. Approval managed start to finish.
⏱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.
⏱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
Buildana handles Cromer KDR end-to-end — old house out, new house in, one contract, one contractor, one defined timeline.
