Custom Home Builder Frenchs Forest — Start in 12 Weeks

Quick Answer
A custom home in Frenchs Forest costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Northern Beaches Council approvals and fixed-price construction.
Frenchs Forest Custom Home Construction
A custom home in Frenchs Forest is a bushland-fringe family build in a suburb reshaped by the Northern Beaches Hospital. The streets run 1960s to 1980s brick on 600 to 900m2 blocks with sandstone topography, and at a $2.2M to $3.4M market a designed replacement is a strong play in a green, well-serviced setting. The hospital, which opened in 2018, drives steady medical-staff demand across the area.
This is Hawkesbury Sandstone, so rock excavation runs $40K to $120K on many sites and is priced honestly up front. Bushland-fringe lots carry a BAL rating from 12.5 up to 29, so the construction spec answers the bushfire risk where it applies. The generous blocks open single or double-storey family designs, close to Forest High School and the Forest Way shops.
What I would check first on your Frenchs Forest block: the rock and substructure, any BAL rating on the bush edge, and the building envelope. Those set the home.
We build these fixed-price, licence HBL 487805C. Bring us your block and brief and we will draw it.
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

How It Works
From First Call to Final Key
We start with a site visit or showroom meeting to talk through what you want to build on your Frenchs Forest block. We'll review Northern Beaches Council's planning controls for 600–900m² lots with R2 Low zoning and give you a straight answer on budget and feasibility.
⏱Design starts with site analysis — sun path, prevailing breeze, neighbour overlooking, slope, view lines from each likely living area. The plan is drawn to that, not dropped onto the block. Two design options usually, sometimes three, then you pick the direction and we refine.
⏱Working drawings, structural engineering (Class Hawkesbury Sandstone soil design), BASIX certification, geotechnical report, stormwater plan and all certification documentation prepared.
⏱Most custom homes in Frenchs Forest qualify for CDC with a 10–15 business day turnaround. If DA is required through Northern Beaches Council, we manage the full submission and respond to any requests for information. Construction Certificate follows.
⏱Construction is run from a programme, not made up week to week. Trade sequencing is locked in advance so the slab cures into a waiting frame and the frame waits for nothing. That's how a 24–40 week build actually delivers in 24–40 weeks instead of running 60+.
⏱Walk through your finished home, collect keys, and move in. OC issued, defect-free inspection completed, 6-year structural warranty, and full maintenance guide provided.
⏱Quality Promise
We build custom homes in Frenchs Forest the way they should be built — one contractor, fixed price, accountability at every stage.
