Design Science is a Gold Coast building design practice led by David Steadman — one of few Australians holding both a QBCC Builder's Licence and a Building Designer licence. We design custom homes, renovations, and extensions that are buildable to budget. Using a Trimble X9 3D laser scanner, we capture your existing home exactly as-built, then design around real measurements — backed by full 3D modelling and detailed construction documentation. Serving the Gold Coast and South East Queensland by appointment.
