How it works

Enter the home area, construction method, storeys, finish standard and delivery model. The result breaks the plan into foundations, shell, envelope, systems and finishing, with materials and labor shown separately.

What affects the result

Area is only one driver. Geometry, masonry or timber construction, finish level, garage, basement and whether work is contractor-led, mixed or owner-managed can all change the budget.

What is included

The model covers typical work beneath and within a single-family house: foundations, structure, roof, external openings, systems, normal logistics and standard finishing.

What is not included

Land, design, surveys, geotechnical work, permits, utility connections, special foundations, landscaping, furniture and items beyond the chosen profile are excluded.

How to use the estimate

Save the assumptions and compare contractor quotes against the same scope. Use the specialist calculators next so stage budgets do not overlap.
