What Determines Whether Land Can Be Developed?
Councils assess a wide range of factors when considering whether land is suitable for development. Whilst every site is unique, the decision is rarely based on a single issue. Instead, councils will typically examine the overall planning merits of a site and whether it represents a sustainable, available and achievable development opportunity.
Key considerations often include the site's location, its relationship to existing settlements, access to services and facilities, highway connectivity, environmental constraints, flood risk, landscape impact, heritage considerations and infrastructure capacity. Authorities will also assess whether the land can realistically be delivered within the relevant planning period and whether development would align with local and national planning policy objectives.
Importantly, the presence of a constraint does not automatically prevent development. Many successful developments have been delivered on sites affected by issues such as flood risk, landscape sensitivities, ecological considerations or heritage assets, provided that appropriate mitigation measures can be implemented. The overall balance of planning considerations is therefore often more important than any single factor.
Ultimately, planning authorities are seeking sites that can contribute towards future housing, employment or economic growth needs in a sustainable and deliverable manner. Understanding how a site performs against these criteria is often the first step in assessing its development potential and future value.
Councils assess a wide range of factors when considering development proposals, including:
Location
Location remains one of the most important considerations. Land is generally more attractive where it:
- Adjoins existing development
- Sits on the edge of a village or town
- Has access to local services
- Benefits from transport connections
Housing Need
Areas experiencing strong housing demand often provide greater opportunities for development.
This is particularly relevant where councils are struggling to meet Government housing requirements.
Planning Policy
Every council operates within a planning framework that influences where growth is expected. Key considerations include:
- Settlement boundaries
- Local Plan allocations
- Green Belt designations
- Housing land supply position
Access
Safe access to the public highway is essential. Whilst access issues can often be resolved, they remain a critical planning consideration.
Environmental Constraints
Factors such as flood risk, ecology, heritage assets and landscape considerations can influence development potential. However, constraints do not necessarily prevent development. Many successful sites contain challenges that can be addressed through good planning and design.
Why Land Without Planning Permission May Still Be Valuable
One of the biggest misconceptions among landowners is that land has little value until planning permission is secured. In reality, land can possess significant value long before a planning consent is granted if there is a realistic prospect of future development. Developers, promoters and investors often look beyond a site's current planning status and assess its long-term potential, recognising that future planning opportunities can create substantial value.
Factors such as Local Plan reviews, Call for Sites submissions, settlement boundary changes, housing land shortages, infrastructure investment and strategic growth proposals can all influence how a site is viewed by the market. Where there is a credible route towards future development, buyers may be prepared to pay significantly more than existing use value in anticipation of future planning gains.
This additional value is often referred to as hope value and reflects the market's assessment of a site's development prospects. Whilst planning permission will generally produce the greatest increase in value, the possibility of securing planning permission in the future can itself be highly valuable. For this reason, landowners should not assume that land without planning permission lacks development value. Understanding a site's planning potential is often just as important as understanding its current use when assessing what it may be worth.
In reality, many developers actively seek sites with future planning potential.
Sites can gain value through:
How Landowners Unlock Development Value
The most successful development sites are rarely brought forward by chance. In many cases, value is unlocked through a strategic and carefully planned approach that identifies opportunities, addresses constraints and promotes the land through the planning system over a period of time. Landowners who achieve the strongest outcomes are often those who understand the importance of planning policy, Local Plan reviews and long-term development potential rather than focusing solely on a site's current use.
Strategic land promotion can involve submitting land through Calls for Sites, engaging with Local Plan consultations, commissioning technical assessments and pursuing planning applications where appropriate. By actively promoting a site and ensuring that its merits are clearly demonstrated to decision-makers, landowners can significantly improve the likelihood of future development opportunities being recognised.
Importantly, development value is often created long before planning permission is granted. The identification of strategic growth areas, emerging Local Plan allocations, settlement boundary reviews and other planning policy changes can all increase market interest and enhance value. By taking a proactive approach and understanding the planning process, landowners can place themselves in the strongest possible position to maximise the future potential of their land and achieve the best possible outcome when the time comes to sell.
