Engineering & approval
Structural drawings and council approval before a stump moves, so the raise is certified, not guessed at.
The raise itself
The house comes up on hydraulic jacks in a single coordinated day, new steel or hardwood stumps set underneath.
The build underneath
Framing, plumbing, electrical and stairs, turning the understorey into rooms rather than storage.
Services & connections
Power, water and drainage rerun to the new level, inspected and signed off before the plaster goes up.
