Home Renovation Builder in Double Bay
A home renovation in Double Bay serves harbourside premium — Federation mansions and inter-war stock on 250 to 1,000m² blocks falling to the harbour beach, with HCAs over most streets and the Bay Street village setting the standard.
The renovation conserves the period fabric and opens the home to the water and the village lifestyle — fall engineered, interiors rebuilt to the standard the postcode expects.
The pre-war fabric gets licensed lead-paint and asbestos handling, with the sandstone read by geotech on the falling lots.
We renovate fixed-price, licence HBL 487805C. Get our renovation scope, with heritage and fall resolved, before you commit.

The postcode sets the standard
Double Bay's values demand the renovation be exact — conserved Federation and inter-war fabric, interiors rebuilt beautifully, and the harbour fall worked for outlook and light.
The village lifestyle on Bay Street is the premium; the home has to match it.
Harbour fall, sandstone, fabric
The substantial fall to the harbour engages engineering early, the sandstone is read by geotech, and the pre-war hazards are licensed processes.
All priced into the scope upfront.

How It Works
From First Call to Final Key
A Double Bay renovation starts with what's worth keeping. Character floorboards, structural brickwork, original joinery — if it earns its place, it stays. Everything else gets a hard look.
⏱Design is pragmatic. Removing the right wall to open a kitchen, upgrading the bathroom to function properly, fixing the laundry that was an afterthought in 1975. Structural engineer signs off before anything load-bearing moves.
⏱Construction runs in stages so you can live in the house for parts of it. Wet areas and kitchens get a clear programme — three weeks without a kitchen is normal; three months is someone else's job.
⏱Handover is clean. New work tied into old work with matched finishes, defects fixed before you move back into the finished zones, warranty on all new work.
