Freshwater Granny Flat Construction — Fixed Price
Freshwater is a tight-knit oceanfront village, and a granny flat here depends a lot on where your block sits relative to the heritage core and the beach. The village is a Heritage Conservation Area — the Duke Kahanamoku surfing legacy runs deep here — so blocks in it go down the DA path with a design that respects the older streetscape.
The blocks run 450 to 800m², so on the streets set back from the beach there's usually room for a second dwelling. On the direct beachfront the coastal hazard zone has a say, and salt air pushes the material spec up.
Underneath it's Hawkesbury Sandstone, so rock excavation is part of most builds — commonly $40,000 to $110,000 here depending on depth. I get a bore done so the rock's in the number.
Fixed price with the heritage, coastal and rock all checked first. Licence HBL 487805C.
Buildana manages the full granny flat process in Freshwater — 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.

Heritage core sets the process
The Freshwater village is a Heritage Conservation Area, so if your block sits in it a second dwelling is generally a DA rather than a fast-track, with a design that sits comfortably behind the original house. It's more process, but the village character is exactly why people build here, so it's worth doing sympathetically.
Set back from the core, on the wider residential streets, the 450 to 800m² blocks are workable and the build is more standard.
Beach and bedrock
On the direct beachfront the coastal hazard zone applies and salt air means corrosion-rated fixings and a salt-tolerant façade — build it once, properly, because cheap fixings rust out fast this close to the sea.
The sandstone means rock excavation on most blocks, commonly $40,000 to $110,000 here. I get the ground tested so that's a real figure in the fixed price. A quality flat in a suburb like this holds its value.
