Developer flagship
Development appraisal & GDV calculator.
Land, build, finance and fees resolve into gross development value, profit on cost and GDV, and a residual land value. The full appraisal an investor runs before making an offer on a site.

Indicative only. A residual appraisal, not a red-book valuation. Finance is modelled on ~50% average drawdown; SDLT uses non-residential slice rates. Confirm figures with your QS and lender before you offer.
How this is calculated
- GDV = units × average sale price.
- Build = area × £/sq ft. Fees & contingency are % of build.
- Finance ≈ (land + build) × 50% average balance × rate × term.
- Profit = GDV − all costs. Profit on cost = profit ÷ total cost.
- Residual land value back-solves land so the deal hits your target profit on cost.
