Clontarf Home Renovations
A home renovation in Clontarf works the Middle Harbour premium — Federation and inter-war heritage on 600 to 1,500m² blocks falling to the water near the Spit, where the harbour-front market rewards exactness.
The renovation conserves the heritage the HCA streets protect and opens the home to the harbour — levels engineered down the fall, deep rock priced from the geotech, and the Foreshore Building Line mapped on the waterfront.
Lead paint and asbestos in the pre-war fabric run as licensed processes.
We renovate fixed-price, licence HBL 487805C. Get our renovation scope, with rock, fall and foreshore resolved, before you commit.

The harbour-front standard
Clontarf's Middle Harbour frontage carries one of the peninsula's strongest premiums, and the renovation meets it — conserved Federation fabric, interiors rebuilt beautifully, and living reoriented down the engineered fall to the water.
The 600 to 1,500m² blocks give the redesigns generous room.
Rock, fall and foreshore
Deep rock excavation is typical where structure changes — priced from the geotech — with the fall engineered early and the Foreshore Building Line mapped on the waterfront lots.
All in the scope before you commit.

How It Works
From First Call to Final Key
We bring our trade leads (electrical, plumbing, structural) on the first visit when scope warrants it. They check what's behind the walls and the floor, which is where the real cost variation sits.
⏱We design the renovation around how you use your home — kitchen layout, bathroom placement, storage, lighting, and flow between rooms. Material and colour selections with our design consultant.
⏱The approval-or-not question hinges on whether walls move, openings change in external walls, wet areas relocate, or load-bearing structure is altered. Buildana checks the scope against Northern Beaches Council's exempt and complying development tests on day one — no late-stage approval surprises.
⏱Renovation works completed room by room where possible — kitchen, bathrooms, living areas. Staged approach minimises disruption.
⏱Renovation complete — final clean, defect inspection, and handover. Warranty covers all work (6-year structural, 2-year non-structural).
⏱Quality Promise
Our Clontarf home renovations respect what's worth keeping and replace what isn't. Structural assessment first, staged build second.
