Properties With Planning Potential UK - What Investors Should Look For

Explore properties with planning potential UK, including development opportunities, change of use, extensions, conversions, redevelopment sites and the key planning checks investors should make before buying.

Properties with planning potential can offer investors and developers an opportunity to create additional value from buildings or land that are currently underused, outdated or unsuitable for their highest-value use.

A property may have potential for an extension, conversion, additional homes, a change of use or complete redevelopment. However, potential is not the same as planning permission, and investors should avoid paying a premium based solely on an assumption that a future application will be approved.

In England, current national planning policy is set through the National Planning Policy Framework, while local plans and other planning considerations influence individual development decisions.

What Are Properties With Planning Potential?

Properties with planning potential are buildings or sites where there may be a realistic opportunity to obtain permission for development or change the property's existing use.

Examples can include:

• Houses with substantial extension potential

• Large homes suitable for subdivision

• Commercial buildings that could potentially be converted

• Former offices

• Vacant retail premises

• Warehouses and industrial buildings

• Brownfield development sites

• Large gardens with possible development potential

• Underused car parks

• Mixed-use properties

• Buildings suitable for additional floors

• Sites that could accommodate new residential units

The potential value comes from what the property could become rather than simply what it is today.

Why Investors Look for Planning Potential

A property with development potential can sometimes be worth more after planning permission is obtained.

For example, an investor might purchase an older commercial building and investigate whether it could become residential accommodation.

Alternatively, a large house might offer potential for an extension or additional units subject to the relevant planning and building regulations requirements.

The difference between the property's existing value and its potential development value can create planning uplift.

However, the investor must account for planning costs, construction, professional fees, finance, taxes and other development expenses.

Types of Properties With Planning Potential in the UK

Planning potential can appear in several different property categories.

Large Residential Properties

Large houses with substantial gardens, unused outbuildings or unusual layouts can sometimes provide opportunities for extensions, reconfiguration or additional accommodation.

The planning position will depend on factors such as the property's location, local planning policies, design and surrounding development.

Commercial Properties

Commercial buildings can sometimes have potential for redevelopment or a change of use.

Potential examples include:

• Offices

• Shops

• Warehouses

• Former restaurants

• Workshops

• Industrial buildings

• Mixed-use premises

A change from commercial to residential use can create significant development value where the planning framework and physical characteristics of the building support the proposal.

Brownfield Sites

Previously developed land can be particularly relevant to property investors searching for development opportunities.

Government guidance on identifying sites for development specifically recognises vacant and derelict land and buildings, commercial buildings and car parks as potential sources of redevelopment opportunities.

Underused Urban Sites

Urban areas can contain sites where the existing use does not make full use of the land.

Examples could include:

• Low-density commercial premises

• Oversized plots

• Redundant buildings

• Surface car parks

• Former industrial sites

• Underused mixed-use properties

The development potential of these sites needs to be assessed against local planning policies and physical constraints.

How to Identify Properties With Planning Potential

Finding a property with planning potential requires more than searching property listings.

Investors should investigate several sources of information.

Review Planning History

Look at previous planning applications for the property and neighbouring sites.

Planning history can reveal:

• Previous applications

• Approved schemes

• Refused applications

• Existing permissions

• Conditions

• Previous changes of use

• Extensions that have already been considered

Planning applications and development proposals are generally made publicly available through the relevant local authority. GOV.UK also provides a service for finding local planning decision registers.

Study the Local Plan

The local plan can provide important information about how an area is expected to develop.

It can identify policies concerning:

• Housing

• Employment

• Retail

• Transport

• Conservation

• Density

• Design

• Green space

• Regeneration

• Development locations

A property's planning potential should therefore be assessed against the policies applying to its specific location.

Examine Neighbouring Development

Nearby planning applications can provide useful context.

If neighbouring properties have recently obtained permission for extensions, conversions or redevelopment, this may provide evidence about the planning characteristics of the area.

It does not guarantee approval for another property, but it can help establish what types of development have previously been considered.

Properties With Potential for Residential Conversion

Residential conversion is one area that attracts considerable investor interest.

Potential properties may include:

• Offices

• Shops

• Former care facilities

• Commercial buildings

• Warehouses

• Mixed-use premises

However, investors should not assume that every commercial building can be converted into flats.

Factors such as natural light, access, floor-to-ceiling heights, layout, parking, fire safety, building regulations, design and planning policy can affect whether a conversion is practical.

Where permitted development rights are relevant, the specific rules and limitations should also be checked rather than assuming that planning permission is unnecessary.

Properties With Extension Potential

Planning potential does not always mean creating several new homes.

A property may have value-creation potential through an extension.

Potential projects include:

• Rear extensions

• Side extensions

• Loft conversions

• Additional floors

• Outbuilding development

• Internal reconfiguration

The potential financial return depends on the relationship between the cost of the work and the additional value created.

An expensive extension that adds less value than it costs may not represent a sensible investment opportunity.

Properties With Redevelopment Potential

Some properties are more valuable as redevelopment sites than as existing buildings.

An investor might identify:

• A dated office building

• A redundant industrial site

• An obsolete retail property

• A large low-density site

• A property with significant unused land

The existing structure may have limited long-term value, while the underlying site could have greater development potential.

This is particularly relevant in locations where demand for housing or mixed-use development is strong.

What Makes a Property Attractive for Planning Potential?

There is no single characteristic that guarantees development potential.

However, investors often investigate properties with combinations of:

• Strong local housing demand

• Accessible transport links

• Previously developed land

• Underused buildings

• Large plots

• Suitable surrounding development

• Established infrastructure

• Nearby regeneration

• Flexible existing use

• Favourable local planning policies

Government site-assessment guidance uses concepts including suitability, availability and achievability when assessing whether sites have realistic development potential.

These principles are useful for private investors as well.

Location Matters When Buying Planning Potential

A property may look attractive on paper but have limited development potential because of its location.

Investors should investigate:

• Local planning policies

• Conservation areas

• Listed-building restrictions

• Green Belt considerations

• Flood risk

• Highways access

• Protected trees

• Heritage constraints

• Environmental restrictions

• Infrastructure capacity

• Neighbouring properties

The current National Planning Policy Framework provides the national planning policy context in England, but local circumstances remain important when assessing an individual property.

Planning Potential Does Not Mean Planning Permission

This distinction is essential.

A property advertised as having "planning potential" does not necessarily have an approved planning application.

There is a significant difference between:

Planning potential - an investor believes development may be possible.

Planning application - a formal proposal has been submitted.

Planning permission - the relevant authority has granted permission, subject to any conditions.

Implemented permission - the permitted development has actually commenced or been carried out in accordance with the permission.

The price of a property should reflect the level of certainty.

How to Value Properties With Planning Potential

Valuing these properties can be more complicated than valuing ordinary residential property.

An investor may need to consider:

Existing property value

What is the property worth in its current condition?

Potential completed value

What could the property be worth after the proposed development?

Development costs

How much will the construction and professional work cost?

Planning costs

What will consultants, surveys and applications cost?

Finance

How much will borrowing cost throughout the project?

Planning obligations

Could Section 106 or other obligations affect the project?

CIL

Could Community Infrastructure Levy apply?

Professional fees

What will architects, surveyors, engineers, solicitors and other specialists cost?

Contingency

How much should be allowed for unexpected costs?

The remaining amount helps establish whether the acquisition price makes sense for the proposed project.

An Illustrative Planning Potential Example

Imagine an investor identifies a commercial property for £750,000.

The investor believes the building could potentially be converted into six apartments.

After professional assessment, the estimated completed value is £1.8 million.

That £1.05 million difference is not automatically the investor's profit.

The project could involve:

• £550,000 construction costs

• £100,000 professional and planning costs

• £75,000 finance costs

• £50,000 contingency

• Additional taxes and transaction costs

The actual development margin would therefore be significantly lower than the headline difference between the purchase price and projected completed value.

This is why a proper development appraisal should be completed before committing to the purchase.

Check Planning Obligations and Development Costs

Planning permission can come with conditions and obligations that affect the economics of a project.

Depending on the development, investors may need to consider:

• Section 106 obligations

• Community Infrastructure Levy

• Affordable housing requirements

• Highways works

• Infrastructure requirements

• Landscaping

• Environmental mitigation

• Design conditions

These costs can materially affect the amount a developer can afford to pay for a property.

Properties With Planning Potential in London

London contains a wide variety of properties that investors may investigate for development potential.

Potential categories include:

• Former offices

• Mixed-use buildings

• Commercial premises

• Large houses

• Industrial buildings

• Underused sites

• Buildings near regeneration areas

• Properties close to major transport infrastructure

Areas such as Croydon, Brent, Greenwich, Tottenham, Stratford, Wembley and parts of East London contain different forms of redevelopment and regeneration activity.

However, planning potential should always be assessed at property level rather than assuming that an entire borough or neighbourhood will support the same type of development.

Properties With Planning Potential Outside London

Planning-led investment is not limited to London.

Investors may investigate opportunities in cities and regional centres including:

• Manchester

• Birmingham

• Bristol

• Leeds

• Liverpool

• Glasgow

• Edinburgh

• Nottingham

• Sheffield

• Newcastle

The economics can differ significantly between locations because acquisition prices, construction costs, rents, sale values and planning policies vary.

For Scotland and Wales, investors also need to consider the different planning and property systems applicable in those nations.

How to Find Emerging Development Opportunities

Local authorities increasingly use site-identification exercises and "calls for sites" to identify land that may have future development potential.

The current government guidance describes calls for sites as a way of gathering potential development sites from landowners, developers and other stakeholders.

Some councils also publish submitted sites and planning information through online mapping systems.

These resources can help investors identify areas where future development is being considered, although inclusion in a call for sites does not mean that planning permission will ultimately be granted.

Questions to Ask Before Buying

Before purchasing a property because of its planning potential, ask:

• What is the property's current lawful use?

• What planning applications have previously been submitted?

• What has been approved or refused?

• What does the local plan say about the site?

• Is the property listed?

• Is it within a conservation area?

• Are there environmental constraints?

• What development could physically fit on the site?

• What comparable developments exist nearby?

• What could the completed property realistically be worth?

• What will construction cost?

• Could Section 106 obligations apply?

• Could CIL apply?

• How long could the project take?

• What happens if planning permission is refused?

• What is the exit strategy?

These questions help separate a genuine development opportunity from a property being marketed with speculative planning language.

Planning Potential and Property Refurbishment

Some opportunities combine planning potential with refurbishment.

For example, an investor could acquire an older property, obtain permission for a new layout or use, then undertake substantial refurbishment before letting or selling the completed property.

Fraser Bond can support the operational side of these projects through building works, refurbishment, contractor coordination, property repairs, maintenance and property management.

This can be particularly useful where the investment moves from planning and acquisition into physical delivery.
