A granny flat in Summer Hill depends on the block. This rail-line suburb between Ashfield and Lewisham is Federation cottages, Victorian terraces, inter-war heritage and contemporary apartments on 200 to 500m² blocks, with extensive Heritage Conservation Areas — the larger freestanding cottages clear the 450m² Housing SEPP threshold and take a studio well, while the terraces and tighter blocks can't, so the survey is the honest first step.
Where a block qualifies, Summer Hill station is in the suburb and rental demand is steady. But heritage over much of the suburb means a full DA rather than the fast CDC path, so a secondary dwelling has to be designed to sit properly behind the Federation streetscape.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. 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, heritage and soil scoped first.
Buildana manages the full granny flat process in Summer Hill — 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.

Depends on the block
Summer Hill is cottages, terraces, heritage and apartments on 200 to 500m² blocks with extensive heritage — the larger freestanding cottages clear the 450m² Housing SEPP threshold, while terraces and tighter blocks can't.
The survey is the honest first step, and a qualifying studio lets steadily with the station in the suburb.
Heritage and shale
Heritage over much of the suburb means a full DA, so a secondary dwelling is designed to sit behind the Federation streetscape.
The Wianamatta Shale grading M means a stiffened-raft slab engineered off a geotech, and older stock can carry fibro.

How It Works
From First Call to Final Key
We inspect your Summer Hill block — lot size (typical 200–500m²), setbacks, services, access, Class M soil check and Inner West Council requirements. You'll know if a granny flat is feasible before spending a dollar.
⏱Design phase covers layout, orientation on your Summer Hill block, bathroom and kitchen placement, natural light, privacy screening, and entry path. You approve the design before we move to certification.
⏱Approval pack lodged with our preferred private certifier (Buildana works with several across the Inner West area). They've reviewed our designs before, know our documentation standard, and turn approvals around at the fast end of the legislated window.
⏱Construction runs 10–16 weeks from slab pour. Class M engineered slab, timber or steel frame, Colorbond roof, full internal fit-out, and separate service connections. Weekly updates from your project manager.
⏱Handover documentation includes everything you need to list with a property manager: OC, BASIX, structural cert, appliance manuals, separate metering details. Photos for the listing taken before furniture goes in. Most Summer Hill GFs lease within 2 weeks.
