Home Extension Builder in Fairlight
A home extension in Fairlight chases the harbour — Federation homes on 350 to 700m² blocks a walk from the pool and the Manly path, where the level up claims water the originals never saw.
The heritage streets extend behind their conserved faces, the sandstone fall shapes the engineering, and the premium contemporary infill sets the finish bar.
At the $3.0M to $6M+ harbour-front market, the addition done exactly is the natural investment.

The harbour is one level up
Fairlight's fall toward the harbour puts water views a storey above most original rooflines — and the set-back addition claims them while the conserved Federation face keeps the street.
The walk-to-Manly position holds every metre added.
Rock and fabric handled
The sandstone is read before any dig, and lead paint joins asbestos on the pre-war fabric — licensed processes both.
The rock read and the licensed strip-out are both costed up front.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We assess your Fairlight home — existing structure, block size (350–700m²), R2 Low zoning, setbacks, FSR, and your space requirements. You'll know what's achievable before spending on detailed design. Design phase covers the extension layout, junction with existing structure, window and door placement, and external finish to match your Fairlight home's streetscape. Multiple design options presented.
⏱The Fairlight construction phase. Fixed price, programmed, supervised. Documentation pack covers structural engineering for the new footings sized to match existing depths on Class Hawkesbury Sandstone soil, BASIX 2025 compliance, shadow diagrams to neighbours' POS, hydraulic, and detailed sections through the wall-tie junction. Approval-grade, not concept-grade. Fixed-price construction of your extension. New footings engineered for Class Hawkesbury Sandstone soil, structural connection to existing home, frame, fit-out, and finishes. Weekly updates from your project manager.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover documentation covers the new work specifically — OC for the extension, structural certs, BASIX certificate updates, and warranty for the new section plus the junction detailing. Existing house remains under whatever warranty position applied before.
⏱Quality Promise
Our Fairlight home extensions connect old-to-new cleanly. Matched brickwork, tied roofline, no awkward transitions.
