What Is Off-Market Investment? A London Commercial-to-Residential Case Study

How off-market commercial buildings are converted into luxury residential through planning gain — with a real Prime W2 numerical breakdown.

A typical agent sells properties at market price via listings like Rightmove. Off-market investment operates in a different world — we source buildings held by funds or institutional owners, often acquired 10–20% below RICS valuation, before they ever reach the market.

Why off-market?

  1. Price advantage: No competitive-bidding environment
  2. Planning upside: Unexploited planning rights
  3. Use-class conversion: Commercial (E Class) → residential (C3) driving 40–60% GDV uplift

A real example: Prime W2 Conversion

  • Acquisition: £6,450,000 (off-market, Grade II listed commercial building)
  • SDLT: £272,500
  • Planning + design: £100,000
  • Conversion works: £1,932,000
  • TOTAL COST: £8,890,949

Exit:

  • GDV range: £13M – £14M
  • Gross value uplift: £4.1M – £5.1M
  • Duration: 16–18 months

Risk profile for the investor

Off-market + planning conversion captures most of the value uplift in stages you control. Dependence on broader market movement is materially lower than in a standard market purchase.
