Builder Gymea, Sutherland Shire
Gymea is a quiet residential suburb between Miranda and Sutherland — 1960s–1990s fibro and brick veneer on 550–800m² R2 blocks. Gymea Bay extension to the south reaches Port Hacking foreshore with associated Foreshore Building Line scope on water-frontage lots. Mature canopy trees protected by Sutherland Shire Council's tree preservation order — engineered building exclusion zones around significant trees commonly remove 5–12% of buildable footprint. End values $1.5M–$2.1M on a 280m² rebuild on standard R2; $2.2M–$3.8M on Gymea Bay foreshore.
