Granny Flats Designed for Earlwood Blocks
A granny flat builder in Earlwood works with an established inner-west suburb of generous blocks near the Cooks River. The 1920s to 1960s character stock sits on generous 500 to 800m² blocks, so most clear the 450m² threshold for a 60m² secondary dwelling under the Housing SEPP, and the inner-city proximity supports strong rental demand. A secondary dwelling here lets well to professionals and families.
The ground here carries reactive clay to design the slab against off geotech, and stiffened rafts are common. The older character homes often carry fibro in additions, so a licensed asbestos strip-out comes first if demolition is involved. The generous backyards make the rear-yard dwelling straightforward.
What I check first on your Earlwood block: the rear-yard access and setbacks, the slab off geotech, and any asbestos. Those decide the build and the yield.

Generous blocks close to the city
Earlwood combines something you do not always get together: generous 500 to 800m² blocks and genuine inner-city proximity. Most of these blocks clear the 450m² Housing SEPP threshold, so a 60m² secondary dwelling is achievable, and the closeness to the city and the Cooks River foreshore supports strong rental demand from professionals and families. The yield here is solid.
The generous backyards make fitting the rear-yard dwelling with proper separation and access easy, which is where tighter inner-west suburbs struggle. The survey check still leads.
Reactive clay and asbestos in character homes
The Earlwood ground carries reactive clay, so the granny flat slab is engineered as a stiffened raft off a real geotech, which keeps it stable against clay movement. The 1920s to 1960s character homes often carry fibro in their additions, so a licensed asbestos strip-out comes first if any demolition is involved. I design the separate access and private open space to keep the dwelling lettable.
