Land acquisition

Buying land or sites for development, often subject to planning.

beginnerprofessional

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

  • Planning application and consultants (transport, ecology, flood)
  • Biodiversity net gain
  • s106 / CIL
  • Site investigations

Potential returns

Planning uplift can be large but is uncertain and slow.

Main risks

  • Planning refusal
  • Access or ransom strips
  • Contamination
  • Utilities capacity
  • Market change during long timescales

Legal checks

  • Title, rights of way, ransom strips, restrictive covenants
  • Option or conditional contract terms

Regulatory checks

  • Local plan policies
  • Biodiversity net gain (10% for most developments in England)
  • Environmental designations
