Land acquisition
Buying land or sites for development, often subject to planning.
Professional analysis
Use residual appraisal and consider option agreements, conditional contracts (subject to planning) and promotion agreements to manage planning risk. Check the brownfield register, local plan allocations, constraints (flood zone, heritage, ecology, BNG), access and utilities capacity. Plotlumen's opportunity finder searches the brownfield register.
Capital requirements
Land price plus planning, surveys and legal costs; development finance follows planning.
Cost assumptions to budget for
