Granny Flat Builder Dundas Valley — Approval in 10 Days, Finished in 14 Weeks
Dundas Valley 2117 secondary dwellings via the NSW Affordable Rental Housing SEPP. CDC fast-track (10–15 days), construction in 14–20 weeks. Free site check.
Dundas Valley Secondary Dwellings
A granny flat builder in Dundas Valley works with the quiet post-war family suburb — 1950s–1970s brick on 550 to 750m² R2 lots. Most clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling is achievable, and this is a strong granny flat and duplex market on the larger blocks.
The regular block sizes and quiet leafy streets make this straightforward — there's usually genuine room to site a studio behind the existing home. R3 pockets along Kissing Point Road are geared to medium-density, so the granny flat suits the settled R2 majority.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. The post-war stock frequently carries 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 Dundas Valley — 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
We inspect your Dundas Valley block — lot size (typical 550–750m²), setbacks, services, access, Class M soil check and City of Parramatta Council requirements. You'll know if a granny flat is feasible before spending a dollar.
⏱Design phase covers layout, orientation on your Dundas Valley 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 City of Parramatta 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 Dundas Valley GFs lease within 2 weeks.
