Start with the expensive-to-change parts
Site position, foundations, structural grid, roof strategy, wet core and utility routes should anticipate likely expansion.
Match stages to finance and household priorities
A household may prioritise sanitation and a safe core first, then bedrooms, living space or an income-generating additional unit later.
Keep every stage documentable
Configurations, quotations, approvals, inspections and installed components can remain attached to the project record.
