A home renovation in Castle Cove costs $100,000–$500,000+. Kitchen from $30K, bathroom from $20K, full renovation from $150K. Buildana manages design, Willoughby City Council approvals (where required), and construction under one fixed-price contract.
Modernising Castle Cove Homes
A home renovation in Castle Cove works the Middle Harbour ridge — 1960s to 1990s homes on 700 to 1,200m² bush-edge blocks with significant slope, where the setting rewards renovation and the terrain demands engineering.
The era is good renovation material: sound structure, dated interiors, and sitings that often ignore the bush and water outlooks. Structural changes on the sloping lots engage geotech and engineered footings early.
On the bush-fringe streets backing Garigal, BAL ratings shape the external materials. The 1960s fabric takes an asbestos check.
We renovate fixed-price, licence HBL 487805C. Get our renovation scope, with the slope engineered, before you commit.

The ridge rewards the work
Castle Cove's 1960s-90s homes have sound bones and sitings that rarely exploit the ridge — the renovation reorients toward the bush and water, opens the plan, and earns the outlook the block already owns.
The 700 to 1,200m² blocks give the design real room.
Slope, BAL and era
The significant slope on many lots means geotech and engineered footings lead structural changes. Bush-fringe streets carry BAL ratings shaping external materials, and the 1960s fabric gets the asbestos check.
All priced into the scope upfront.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. On-site meeting to walk through your Castle Cove home room by room. We identify what needs to change, what can stay, and where the budget delivers the most impact. Written scope and cost estimate within a week. Design includes selections for everything you'll touch: tapware, tiles, benchtops, splashbacks, joinery handles, paint colours, lighting, flooring. We lock these at design stage with cost-confirmed inclusions, not provisional sums that creep up during construction.
⏱The Castle Cove construction phase. Fixed price, programmed, supervised. If your renovation involves structural work, we lodge DA or CDC with Willoughby City Council. Most kitchen and bathroom renovations don't require approval. Buildana advises on what needs lodgement and what doesn't. Trade sequencing is the difference between a 6-week renovation and a 12-week one. Demo, structural, plumbing rough-in, electrical rough-in, plaster, waterproofing, tiling, joinery install, fit-off, paint — each trade in and out cleanly, no waiting on the next sub.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate (if required), 6-year structural warranty on any structural work, and maintenance guide. Your Castle Cove home, transformed.
