A custom home in Forestville 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.
Custom Homes Designed for Forestville
A custom home in Forestville is an established bushland-fringe build where the sandstone and any BAL rating shape the spec. The suburb runs 1950s 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 family play in a green, settled setting. Forestway Shopping Centre and Bantry Bay in Garigal National Park frame the suburb.
This is Hawkesbury Sandstone, so rock excavation runs $40K to $100K on many sites and is assessed and priced honestly up front. Bushland-fringe lots backing Garigal 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, and a home oriented to the bush makes the most of the position.
What I would check first on your Forestville block: the rock and substructure, any BAL rating backing the park, and the building envelope. Those set the home.
We build these fixed-price, licence HBL 487805C. Bring us your block and outlook and we will design to 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
First meeting is about getting the brief right — number of bedrooms, lifestyle priorities, future-proofing, budget envelope, and what you'd hate to compromise on. We pair that with what your Forestville block actually allows under R2 Low controls. Walk away with a realistic shortlist of design directions.
⏱Floor plan designed specifically for your Forestville block — orientation, setbacks, views, slope, and how you actually live. 600–900m² blocks allow generous layouts. Multiple options, 3D renders, and finishes palette.
⏱We prepare everything needed for approval — engineering drawings sized for Class Hawkesbury Sandstone ground conditions, BASIX certificate, geotech report, survey, and stormwater plan. All documentation handled in-house.
⏱Lodgement, RFI responses, condition negotiation, and CC issue — all managed in-house. Northern Beaches Council has typical processing windows we plan around so the build start date isn't a moving target. You see the lodgement reference, the assessment progress, and the issued certificate at each step.
⏱Construction runs 24–40 weeks depending on size and complexity. Your project manager provides weekly updates with photos and milestone tracking. Every stage is inspected before the next begins.
⏱Handover is a sign-off process, not a key drop. We walk every room with you, mark anything below standard, complete those items before settling, then issue OC, warranty, and documentation. You move in to a finished home, not a defects list to chase.
