What Your Construction Cost Actually Includes
The number on the front page of a builder quote is not the cost of your project. Here is what a complete cost position actually covers.
Most clients enter a construction project with a number in mind. That number usually comes from a friend who built something similar, a rough estimate from a designer, or a figure mentioned at a first meeting. Almost none of these sources are reliable.
What a complete cost position includes
- Building works — structure, roofing, external envelope, internal fitout, wet areas, joinery, and services
- Finishes and fitout — flooring, tiling, fixtures, hardware, appliances, cabinetry, and all finish-level selections
- External works — landscaping, driveway, fencing, pool, and site drainage
- Preliminaries — site establishment, supervision, insurance, and scaffolding
- Authority and statutory fees — development approval, building approval, engineering certification
- Consultant fees — architect, structural engineer, hydraulic engineer, surveyor, and soil testing
- Contingency — an allowance for the unexpected
What builder quotes routinely exclude
Most builder quotes exclude some or all of the following: landscaping, pool, window furnishings, appliances, authority fees, soil investigation, and engineering certification. Always request a written exclusions list before comparing prices.
The four primary cost drivers
- Scale — total floor area is the single largest cost driver
- Specification — the quality of finishes, fixtures, and materials
- Complexity — structural complexity, roof form, wet area count, feature glazing
- Site conditions — slope, access, soil classification, and proximity to services
Why early estimates are unreliable
Cost certainty arrives with documentation, not before it. Early in a project there is very little information to work with, and estimates made at that stage carry a wide margin of error.
Already feeling the budget pressure?
If your project has drifted beyond budget, realignment can bring it back.
