Finding development land

Last reviewed: 15 June 2026

Finding development land means identifying sites where planning, demand, value and build costs can support a profitable project. Developers usually assess location, planning policy, access, constraints, title, utilities, contamination, flood risk, GDV and funding route before making an offer.

How to find development land and assess site viability

Development land represents the raw material for developer projects. Success depends on thorough site assessment before making any offer. This guide covers the key factors developers evaluate when sourcing and assessing land opportunities.

On-market and off-market land

Development land is sourced through agents, auctions, direct-to-owner approaches, local authority disposal programmes and professional networks. Off-market land may offer less competition but requires more proactive sourcing and relationship building.

Brownfield and infill sites

Brownfield sites are previously developed land that may be suitable for redevelopment. Infill sites fill gaps in existing built-up areas. Both may carry planning advantages under local planning policy but require due diligence on contamination, services and access.

Planning policy and local plans

Local planning authorities set out where development is acceptable through local plans and policies. Understanding the planning framework helps developers identify sites with realistic prospects of gaining consent and avoids speculative purchases in areas resistant to development.

Access and highways

Legal access to the site and highway connectivity are fundamental requirements. Missing access rights, ransom strips, or inadequate highway capacity can prevent development. These issues must be checked with the solicitor and highways authority before exchange.

Utilities and services

Development sites need connections to water, drainage, electricity, gas and telecommunications. The cost and feasibility of service connections can vary significantly and should be budgeted early. Utility searches and pre-application enquiries help quantify costs.

Title constraints

Title issues such as restrictive covenants, easements, rights of way, ransom strips and overage clauses can limit development potential or increase costs. The solicitor must review the title and report on constraints before any commitment.

Contamination and flood risk

Environmental risks including contamination from previous industrial use and flood risk from watercourses or surface water must be assessed. Phase 1 desktop studies, flood risk assessments and environmental searches help quantify risk and cost of remediation.

GDV and residual land value

Developers calculate what land is worth by working backwards from GDV: estimated sale value minus build costs, finance costs, professional fees, profit margin and contingency equals the residual land value. This determines the maximum offer price.

Funding and offer strategy

Understanding likely funding terms early helps developers structure competitive offers. Knowing the deposit, LTC, LTV limits and conditions helps decide whether to proceed on an unconditional or conditional basis.

It helps to understand likely funding limits early, but lenders usually need site details, planning position, costs and GDV before issuing terms.
