KBG Planning & Design — formerly Compudraft — has helped Sydney homeowners and investors bring their visions to life since 1983. What began as a small drafting studio is now one of the region's most trusted building design practices.
We work from two studios in Castle Hill and Oatley, with deep local knowledge of the Hills Shire and Sutherland Shire planning controls. We listen first, then design — and we partner with KBG Consulting engineers for a seamless, end-to-end service.
From first sketch to approved plans and full construction drawings — guided every step of the way.
Bespoke single and double-storey homes — and knock-down rebuilds — crafted around your lifestyle, block and budget.
02Second-storey additions, rear extensions and reconfigurations that work with your existing home and council controls.
03Attached and detached dual occupancy designed for approval from day one — across Hills and Sutherland Shire.
04Townhouses and villa developments designed to meet LEP/DCP controls and maximise viable site yield.
05Know what's possible before you commit — development potential, planning controls and pre-purchase due diligence.
Hundreds of Sydney families and investors have trusted us with their most important projects.
They listen to you and create a fantastic design based on your criteria. Can thoroughly recommend them.
The design considered how we live day to day — not just how it looks on paper. The 3D drawings let us feel the rooms before anything started.
James got it through council when it seemed impossible — and the finished home exceeded our expectations. We wish we'd engaged them from the beginning.
