Four defined engagement stages

Know what you receive, who is responsible and where each stage ends

Owner Builder WA can review project fit, prepare the preconstruction plan, coordinate procurement and deliver an agreed structural-shell or lock-up package. Each proposal defines the deliverables, responsibilities, fee basis, timing, exclusions and handover point before work begins.

Clear boundaries from the start

One project can use one stage—or a deliberately connected sequence.

Every accepted proposal identifies what you are managing, what Owner Builder WA is supplying or coordinating, what licensed contractors perform and the exact handover point. Your owner-builder obligations remain yours.
