Aitch Group Acquisition Criteria

Sites are screened against the following fund parameters. Only sites meeting all four criteria are marked as compliant:

• Dwelling capacity: 20–400+ units (suitable for conditional, unconditional, JV, or promotion agreements)
• Estimated land value: £1M–£30M (derived from site hectares × regional land value benchmarks)
• £/sqft zone: £400–£900 psf (derived from Land Registry transaction prices ÷ average floor areas by property type)
• Planning status: All statuses included — not permissioned (highest-value acquisition opportunity), pending decision, and permissioned (conditional/JV/promotion deals)

Geography: Greater London and Home Counties (Essex, Surrey, Hertfordshire, Buckinghamshire, Berkshire, Kent, East Sussex, West Sussex).

Use types: Residential, Retirement Living, PRS, and Mixed Use opportunities all considered. Brownfield register sites are residential by designation.

Scoring (0–100)

Every site starts at 50 points.

• Planning: Not permissioned +15, Pending +10, Permissioned +5
• Units: 20–400 +15, 400+ +10, <20 -5
• Site area: 0.1–5.0 ha +10
• Deliverable: Council-marked deliverable within 5 years +5
• Flood: 0 areas within 3km +5, 1–2 areas -5, 3+ areas -15
• Public ownership: +5 (may offer favourable terms)

Land Value Estimation

Estimated from site hectares × regional residential development land benchmarks (Savills/Knight Frank 2024/25 indices). Ranges from ~£3M/ha (Home Counties) to ~£20M/ha (Central London). These are indicative only — actual site values depend on planning status, density, and scheme viability.

£/sqft Zone Derivation

For each search zone, Land Registry Price Paid transactions are divided by standard floor area assumptions per property type (Flat 55m², Terraced 80m², Semi 95m², Detached 135m²). Where transaction data is sparse, a fallback estimate from the regional land value benchmark is used.
