Granny Flats Designed for West Pennant Hills Blocks
A granny flat builder in West Pennant Hills works with the leafy established Hills suburb — 1970s–1990s brick on generous 700 to 1,200m² R2 lots with established gardens and top schools. They clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling is achievable on most, whether for family or a quality rental with Cherrybrook Metro a few minutes away.
The generous blocks are the advantage here — there's genuine room to site a studio properly without crowding the main house or losing the garden. The premium custom market in this suburb means the granny flat is usually specified to match, not a budget box in the backyard.
The soil sits on the Wianamatta Shale and Hawkesbury Sandstone interface, so a stiffened-raft slab is engineered off a real geotech, with rock possible where the footing meets sandstone. The older stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Survey and soil scoped first.
Buildana manages the full granny flat process in West Pennant Hills — from site assessment and CDC fast-track approval through to fixed-price construction and handover. We build studio, 1-bedroom, and 2-bedroom designs up to the NSW maximum of 60m².

How It Works
From First Call to Final Key
Most West Pennant Hills blocks support a granny flat — the question is where it sits, how it accesses the street, and how it shares the yard with the main house. We work that out on site, with the existing house and existing services in front of us.
⏱1-bed or 2-bed floor plan designed for your West Pennant Hills block — up to the NSW maximum of 60m². Layout, window placement, kitchen and bathroom positioning optimised for liveability and rental appeal.
⏱We lodge your CDC application with all required documentation — BASIX, plans, site analysis, stormwater. Private certifier approval in 10–15 business days.
⏱12-week typical timeline for a 60m² 2-bed: slab pour week 1, frame stand weeks 2–3, lock-up week 5, internal fit-out weeks 6–10, finishes and external works weeks 11–12. We provide the dated programme upfront so you can plan move-in or tenant placement.
⏱OC issued, defect-free inspection completed, keys handed over. Your granny flat is ready to occupy or lease.
