A home extension in Church Point costs $150,000–$600,000+. Rear extension from $150K, second-storey addition from $300K. Buildana manages design, Northern Beaches Council approvals, and construction under one fixed-price contract.
Home Extension Builder in Church Point
A home extension in Church Point is engineered to the water's edge — Pittwater frontage, ferry-wharf village life and 600 to 1,500m² blocks with fall the addition steps down or builds over.
Foreshore building lines cap the push toward the water, BAL ratings apply on the vegetated slopes, and marine-grade materials are standard at the tideline.
In the $3.0M to $8M+ waterfront market, the addition built to the position's standard is the natural investment.
We build these fixed-price, licence HBL 487805C. Show us your gradient and we will design to it.
Buildana manages the complete home extension process in Church Point — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

Designed to the tideline
Church Point's additions work with the water — stepping the fall, opening to Pittwater, holding inside the foreshore building line — with the premium justifying engineering done properly.
Access on the steep lanes is planned into the build, not discovered during it.
Slope, bush and salt
The sandstone fall shapes the structure, BAL ratings apply on the vegetated slopes, and marine-grade materials are standard near the tide.
The engineering, the BAL materials and the access plan are all 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 Church Point home — existing structure, block size (600–1,500m²), 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 Church Point home's streetscape. Multiple design options presented.
⏱The Church Point 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
We extend Church Point homes with a structural engineer on every job. Second storey, rear addition, multi-room — engineered and priced upfront.
