A home renovation in Warrawee costs $100,000–$500,000+. Kitchen from $30K, bathroom from $20K, full renovation from $150K. Buildana manages design, Ku-ring-gai Council approvals (where required), and construction under one fixed-price contract.
Modernising Warrawee Homes
A home renovation in Warrawee is high-end heritage work in one of Ku-ring-gai's smallest premium pockets. The Federation and inter-war homes sit on generous 900 to 1,500m² blocks, and Heritage Conservation Areas cover several streets, so a renovation here restores the period character while modernising behind it. The Knox and Abbotsleigh catchment lifts the floor price, and the heritage is the value.
Any structural change checks the existing footings, and the ground can bring rock on excavation. Any fibro in the later additions is removed under a licensed strip-out first. Most heritage work here goes through a full DA rather than a fast-track path, so the plan respects that from the start.
What I check first on your Warrawee renovation: whether you sit inside a Heritage Conservation Area, the condition of the existing structure, and the depth to rock on any addition. Those shape the scope.

Restore the heritage, modernise behind
Warrawee's Federation and inter-war homes on generous 900 to 1,500m² blocks are genuinely characterful, and with Heritage Conservation Areas over several streets, a renovation restores that period character while opening the rear up to modern living. On these large blocks there is room for a substantial rear addition behind a beautifully restored front, which is the high-value approach the Knox and Abbotsleigh catchment supports.
Most heritage work here goes through a full DA rather than a fast-track path, so the plan is built around the heritage controls from the start. I map the listing and the HCA on your exact block first.
Footings and rock
Any structural change in a Warrawee renovation checks the existing footings before a heavy addition, and the ground can bring rock on excavation, priced from a real assessment rather than assumed. Fibro in the later additions is cleared by a licensed strip-out as part of that work. Handled with the right heritage approach, a Warrawee renovation restores a significant home on a premium block.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Warrawee home — existing condition, renovation scope, structural requirements, and budget. You'll receive a clear overview of costs and timeline before committing. Design phase includes floor plan modifications, 3D kitchen and bathroom renders, material palettes, and electrical layout. You approve every detail before construction begins.
⏱The Warrawee construction phase. Fixed price, programmed, supervised. For renovations that need DA or CDC, we lodge structural drawings, hydraulic if wet areas move, BASIX if envelope changes, and SEE if DA. For pure cosmetic work, no lodgement, no permit fees — straight to scheduling trades. Fixed-price renovation from demolition of existing fittings to final finish. Staged programme keeps parts of your home liveable. All trades coordinated by your project manager with weekly updates.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover includes a defect walk-through where we mark any final touch-ups, complete them within a week, and re-inspect. The end-state is genuinely finished — not handed over with a list to chase trades back for.
