Landowner tools
Practical calculators for landowners considering housing
Start with rough numbers, then move towards a sensible planning and disposal route. These tools are designed for small sites where serviced plots and self-build routes can unlock more value than a conventional developer sale.
Best starting point
If you only use one tool, start with the land value calculator. It gives a quick comparison of the main routes and points you towards the next most useful tool.

Use toolA simple path through the decisions
Landowners usually need three answers: what might it be worth, can it get planning, and who should take the risk. The tools are arranged around that sequence.
