About this tool: Dev Appraisal
Residual development appraisal — Gross Development Value, total costs, developer profit margin, and viability traffic-light assessment.
Use for any development project to test financial viability before committing. Essential for land purchase decisions and investor presentations.
RICS Valuation Standards (Red Book), PPG Viability
Use these tools to understand the financial side of your project — what fees you'll pay, whether the scheme is viable, what CIL/S106 might cost, and whether your land value assumptions stack up. Essential for go/no-go decisions.
Guidance to help you prepare — not formal planning advice. Check the current policy text and your council's local plan before relying on it.
