Granny Flats Designed for Kyeemagh Blocks
Kyeemagh sits right under the flight path — you're between Brighton-Le-Sands and the airport runway approach, and that one fact shapes every granny flat I've priced here more than the soil or the zoning does. The blocks are a comfortable 400 to 700m², post-war brick, so on the space side you've usually got room. The catch is what has to happen to the windows and walls of a second dwelling this close to the runway.
The land is Botany Sands with a high water table, so the footing gets designed for sand rather than clay. That's not a problem, it's just a different detail — a slab or a screw-pile arrangement that suits loose sand, sorted off a geotech report before I quote a number.
Under the Housing SEPP a 60m² secondary dwelling on a lot over 450m² is a fair fit here, and most Kyeemagh blocks clear that. Whether it goes complying-development or lands as a DA usually comes down to the acoustic and foreshore overlays rather than the size.
I build these on a fixed price with the aircraft-noise glazing costed in from the start, not bolted on later. Licence HBL 487805C.

Aircraft noise is the real design driver here
I'll be straight about it — the runway approach is the thing that makes Kyeemagh different. A habitable second dwelling this close needs acoustic treatment to meet the internal noise levels: upgraded glazing, sealed construction, sometimes mechanical ventilation so it still performs with the windows shut. It's doable, it's just a real line in the budget, and I'd rather you see it up front than find it at DA stage.
Because the land is Botany Sands sitting on a high water table, the footing is engineered for sand — that's a geotech call, not a guess. I get the report first, design the slab or piers to suit, and lock the number so it holds.
What actually gets built and what it's worth
On the standard 400 to 700m² block there's room for a proper one or two-bedroom secondary dwelling with its own yard. Close to the Cooks River foreshore the site controls tighten, so I check the mapping before promising anything.
As a rental it holds up — this is a short hop to the airport and to Rockdale, so the tenant pool is steady. I'd just never quote you a weekly figure I can't stand behind; a well-built, well-insulated flat here lets reliably.
