South Penrith Granny Flat Construction — Fixed Price
A granny flat builder in South Penrith works with the established residential suburb south of Penrith CBD — 1960s–1980s brick veneer on 500 to 750m² R2 blocks. Most clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling, and with affordable land out here a studio can let for a healthy yield.
The good block sizes and the settled family character make this straightforward — there's usually genuine room to site a studio behind the existing home, with Southlands Shopping Centre and schools close. R3 medium-density along Maxwell Street is geared to townhouses, so the granny flat suits the settled R2 streets.
The soil is Wianamatta Shale grading M, so a stiffened-raft slab is engineered off a real geotech on the reactive ground. The older brick stock can carry fibro in later additions, 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 South Penrith — 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
Everything that has to be right before we touch the ground. Assessment is the most important hour you'll spend on the project. Get the position, orientation, and access right and the build runs clean. Get them wrong and you're chasing certifier RFIs for months. Buildana checks every constraint before recommending a position. We design your granny flat to maximise the 60m² allowance within Penrith City Council's setback and POS requirements. Floor plan, elevations, and 3D render provided. Studio, 1-bed, or 2-bed configurations available.
⏱The South Penrith construction phase. Fixed price, programmed, supervised. CDC pathway exists specifically for compliant granny flats — use it. No neighbour notification, no Penrith City Council planner queue, no committee politics. Certifier checks the design against the code; if it complies, it approves. 10–15 business days, every time. Fixed-price build: slab (Class M engineered), frame, roof, fit-out, connections. 10–16 weeks depending on size. Minimal disruption to your existing home.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Walk through your finished granny flat, collect keys. Occupation Certificate, 6-year structural warranty, and maintenance guide provided. List for rent immediately — typical demand in South Penrith fills vacancies fast.
