What Total Development Cost actually includes
Every line item beyond the raw construction rate, laid out.
Total Development Cost includes the raw construction cost plus professional fees, statutory and regulatory costs, external works, contingency, cost of funding, and marketing. It's typically meaningfully higher than the construction rate alone, which is why budgeting off a build rate by itself usually understates what a project actually costs.
The construction rate is the number most conversations start with, and the number that leaves out the most when it comes to budgeting a real project.
The full list
- Raw construction cost: materials and labour for the physical build.
- Professional fees: architect, engineer, quantity surveyor.
- Statutory costs: approvals, permits, and regulatory charges.
- External works: fencing, drainage, driveways, landscaping.
- Contingency: a buffer for the unplanned, usually a percentage of build cost.
- Cost of funding: interest or opportunity cost on capital deployed over the build period.
- Marketing: cost of selling or letting once complete.

Is land cost included in Total Development Cost?
Total Development Cost as covered here is the cost of developing the project, land is typically budgeted and evaluated as a separate line alongside it rather than folded into the same figure.
What's typically the biggest line item after raw construction?
Cost of funding and statutory costs are usually the two that surprise developers most, since both scale with build duration and project size in ways a raw construction rate alone doesn't capture.
Why does budgeting off the construction rate alone usually fall short?
The construction rate only covers materials and labour for the physical build. Professional fees, statutory costs, external works, contingency, funding cost, and marketing all sit on top of it, and together they typically add up to a meaningfully higher total.
