Quiet suburbs make good landlords, and Old Guildford is about as quiet as Fairfield LGA gets. A granny flat here rents at $380 to $500 a week to tenants who want Yennora station, one kilometre away, and access to both Fairfield and Guildford centres without paying either's prices. Medians of $900K to $1.15M keep the entry cost sane.
Post-war homes on 450 to 700m² blocks mean most lots clear the 450m² SEPP threshold, though the tighter ones need a proper measure before promises get made. Soil runs M-H, so the geotech report is not optional, it is how the slab price stays honest.
What I would check first on an Old Guildford block: the surveyed size against 450m², the reactive-soil slab from a geotech, and the walk to Yennora. Those set the plan.
We build these fixed-price, licence HBL 487805C. We include the geotech in every quote, so send through your address and we will start with the measurements that matter.
Buildana manages the full granny flat process in Old Guildford — 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. We inspect your Old Guildford block — lot size (typical 450–700m²), setbacks, services, access, Class M–H soil check and Fairfield City Council requirements. You'll know if a granny flat is feasible before spending a dollar. Design phase covers layout, orientation on your Old Guildford block, bathroom and kitchen placement, natural light, privacy screening, and entry path. You approve the design before we move to certification.
⏱The Old Guildford construction phase. Fixed price, programmed, supervised. Approval pack lodged with our preferred private certifier (Buildana works with several across the Fairfield City 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–H engineered slab, timber or steel frame, Colorbond roof, full internal fit-out, and separate service connections. Weekly updates from your project manager.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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 Old Guildford GFs lease within 2 weeks.
