Home Extension Builder in Roselands

Roselands homeowners with 1940s–1970s-era properties are increasingly turning to home extensions to gain space without the disruption of a full move. With typical lots of 500–700m², most Roselands properties can accommodate ground-floor or second-storey extensions under Canterbury-Bankstown Council's planning controls. Buildana manages feasibility, design, approvals, and construction for Roselands extension projects under one fixed-price contract.

Buildana manages the complete home extension process in Roselands — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

How It Works

From First Call to Final Key

We assess your Roselands home — existing structure, block size (500–700m²), R2 Low Density zoning, setbacks, FSR, and your space requirements. You'll know what's achievable before spending on detailed design.

Extension designed to complement your existing home — floor plan, elevations, structural connection details. Canterbury-Bankstown Council compliance built into the design from day one.

DA through Canterbury-Bankstown Council (40–90 days) or CDC (10–15 business days). Construction Certificate obtained before works commence. Buildana manages all submissions.

Extension built with minimal disruption — new footings (Class M soil), frame, connection to existing dwelling, fit-out. Weekly updates from your project manager.

Defect-free handover with seamless connection between old and new. 6-year structural warranty. Your Roselands home — with the space you need.

Quality Promise

Every Buildana home extension in Roselands is delivered under a fixed-price contract — from design consultation through to defect-free handover.
