Love where you live but not your old house? KaiserBuilt demolishes the old and rebuilds a brand-new custom home on your existing block — managing demolition, approvals, engineering and construction from start to finish, at one fixed price.
A knockdown rebuild (KDR) means demolishing your existing home and building a brand-new one on the same block — so you keep the location, the neighbours and the established suburb you love, without the compromises of renovating an old house or the cost and stress of buying and moving.
It is often better value than a major renovation: no matching old structures, no hidden surprises behind the walls, and a home built to today's 7-star energy standard. As experienced Adelaide knockdown rebuild builders, we handle everything — feasibility, demolition, council approvals, engineering and the new build — under one accountable team and one fixed price.
From the first site check to the keys — every stage of your knockdown rebuild handled in-house.
