Add space and value to your home with a professionally built extension. ACG Built specialises in second storey additions, ground-floor extensions and room additions across Caringbah, Cronulla, Miranda, Burraneer, Gymea, Kirrawee, Woolooware and surrounding Sutherland Shire suburbs.
As your family grows, so should your home. A well-designed extension gives you the extra space you need without the upheaval of moving. At ACG Built, we've helped dozens of Sutherland Shire families stay in the neighbourhoods they love by creating beautiful, functional extensions that feel like they were always part of the original home.
We handle every aspect of your extension — from architectural plans and council approvals through to structural engineering, construction and finishing. Our team ensures the new addition blends seamlessly with your existing home, matching rooflines, brickwork and internal finishes so you'd never know it was an add-on.
With deep experience navigating Sutherland Shire Council's development requirements, we keep the approval process moving smoothly. You get a single point of contact throughout the entire build, with regular updates and transparent communication at every stage.
From concept to completion — everything you need to expand your living space
