DO I REQUIRE PLANNING PERMISSION?

Whether you need planning permission in the UK depends on the type of work you plan to carry out. Here are the key considerations:

Permitted Development Rights

Many minor improvements and alterations can be made under "permitted development rights," which do not require planning permission. Check our recent blog post for more details.

Common projects under permitted development include:

Small Extensions: Single-storey rear extensions within specified size limits.

Loft Conversions: As long as they meet specific criteria.

Internal Alterations: Most internal modifications do not require planning permission.

Outbuildings: Certain outbuildings and garden structures can be erected without planning permission.

Solar Panels: Installing solar panels typically falls under permitted development.

Projects Likely to Require Planning Permission

------------------------------------------------------------------------------

However, you will need planning permission for more substantial changes, such as:

Large Extensions: Extensions that exceed the size limits set by permitted development rights.

Change of Use: Changing the use of a building or land (e.g., converting a house into flats).

Listed Buildings: Any work on a listed building or within a conservation area.

Significant External Changes: Changes to the main external appearance, including significant alterations to windows, doors, or roofs.

New Buildings: Constructing new buildings, including new homes or commercial properties.

Certain Outbuildings: Larger outbuildings or those intended for business use.

Checking Specific Requirements with your Local Planning Authority (LPA).

Your Local Planning Authority (LPA) is the primary body responsible for planning permission in your area. It’s essential to check with your LPA, as local regulations and guidelines can vary. You can find information on their website or contact them directly.

Planning Portal

The UK Government’s Planning Portal (Planning Portal) provides comprehensive information on what requires planning permission and what is covered under permitted development. It also offers interactive guides and tools to help you determine if you need permission.

Applying for Planning Permission

If your project requires planning permission, follow these steps:

Pre-Application Advice: Seek advice from your LPA to identify potential issues and understand what information you need to provide.

Prepare Your Application: Gather necessary documents, including site plans, existing and proposed drawings, and a design and access statement if required.

Submit Your Application: You can submit online via the Planning Portal or directly to your LPA.

Pay the Application Fee: Fees vary based on the nature and size of the project.

Public Consultation: Your application will be made available for public consultation.

Decision: The LPA aims to make a decision within eight weeks for most applications.

By understanding the scope of permitted development and the requirements for planning permission, you can better navigate the process and ensure your project complies with local regulations.

ARE UK PROPERTY PRICES GOING DOWN?

UK property prices have been experiencing fluctuations recently, with various factors influencing the market dynamics. According to recent data, the overall trend shows a slight decrease in house prices. 

For instance, Halifax reports that the average house price in May 2024 was £288,688, which represents a 1.5% increase from the previous year but a slight monthly decline of 0.1%​ (Home)​. 

Similarly, Zoopla's House Price Index indicates a minor annual decline in house price inflation at -0.1%, though there has been a modest quarterly increase of 0.4%​ (Zoopla)​.

Several factors are contributing to these changes, including higher mortgage rates, increased supply of homes on the market, and shifting demand patterns post-pandemic. 

The number of homes for sale is at its highest in eight years, with many sellers returning to the market as mortgage rates stabilise and buyer activity increases​ (Zoopla)​. 

However, the increased supply is expected to keep house price inflation in check for the remainder of 2024.

Overall, while there are pockets of stability and slight increases in certain areas, the broader trend suggests a cooling in the housing market, with prices stabilising or slightly declining.

COST OF HOUSE EXTENSION, cost per M2

The cost of a house extension in the UK can vary widely depending on several factors, including the location, type of extension, quality of materials, and complexity of the project. 

However, a general estimate for house extension costs per square meter (m²) can provide a useful starting point.

TYPICAL COSTS:

1.    BASIC EXTENSIONS

Cost Range: £1,200 - £1,500 per m²

Description: This range typically covers basic single-story extensions with standard finishes and minimal customisation.

2.    MID-RANGE EXTENSIONS

Cost Range: £1,500 - £2,500 per m²

Description: Mid-range extensions might include higher-quality materials, more complex designs, and additional features such as bi-fold doors or skylights.

3.    HIGH-END EXTENSIONS

Cost Range: £2,500 - £3,500+ per m²

Description: High-end extensions involve luxury materials, bespoke designs, and high-

specification finishes. These projects might also include advanced technologies and premium fittings.

ADDITIONAL FACTORS AFFECTING COSTS:

LOCATION

Costs in London and the South East are typically higher than in other parts of the UK due to increased labour and material costs.

TYPE OF EXTENSION

• Single-Story Extension: Generally less expensive and simpler to construct.

• Double-Story Extension: More expensive due to additional structural requirements.

• Loft Conversion: Costs can vary but often range from £1,200 - £2,000 per m².

COMPLEXITY OF DESIGN

Simple, rectangular extensions are usually cheaper than those with complex shapes or multiple angles.

Extensions requiring significant structural changes or involving difficult ground conditions (e.g., sloped sites) will also be more expensive.

QUALITY OF MATERIALS AND FINISHES

Basic finishes (standard kitchen units, basic bathroom fittings) will be cheaper than premium finishes (high-end kitchen appliances, luxury bathroom fittings).

PROFESSIONAL FEES

Fees for architects, structural engineers, and planning applications can add to the overall cost. 

These might range from 10% to 15% of the construction cost.

PERMITS AND REGULATIONS

Costs for Planning Permission, if needed . . . . . . check our recent article on Permitted Development), Building Regulation approvals, and other legal requirements should also be factored in.

EXAMPLE BREAKDOWN

For a mid-range single-story extension of 30 m², the estimated costs might be:

• Basic Construction Cost: 30 m² x £2,000 = £60,000

• Professional Fees (10%): £6,000

• Planning Permission: £200 - £500

• Building Regulation Fees: £500 - £1,000

• Contingency (10%): £6,000

Total Estimated Cost: Approximately £72,700 - £73,500
