The cost of a flat roof extension is dependent on a variety of factors including:

• The design/ complexity of the extension
• The size of the extension
• Location
• Groundwork involved
• Building materials
• Fittings and fixtures
• Specialists’ fees, etc.

Therefore, the cost of the extension may range from £45K to £60K.

Not necessarily.

The requirement for planning permission for an extension depends largely on the design and dimensions of the build. More often than not, if the extension falls under permitted developments, planning permission is not required.

However, permitted developments have specific criteria which must be adhered to; such as certain size and height limitations. This includes a maximum height of 4m for single-storey extensions and a maximum width of 50% of the original house for side extensions. Most importantly, the property should not be listed in a conservation area.

The process of applying for and securing planning permission can take up to eight weeks and requires a comprehensive application detailing the proposed extension.

Homeowners must also apply for building regulations approval and secure party wall agreements to ensure that every aspect of the extension build complies with building guidelines and regulations.

We oversee this entire process for all our clients. This includes surveying the location, architectural diagrams, coordinating with the local council, and securing the requisite planning permission and building regulations approval.

Flat roof extensions are popular for various reasons and offer several benefits. Some of the key benefits are listed below:

• Cost Effective- In general, flat roof extensions tend to be more cost-effective compared to pitched roof extensions, largely due to their simpler design.
• Modern Aesthetics- Flat roof extensions are often chosen for their sleek and contemporary appearance. They can provide a minimalist and modern design aesthetic that complements a wide range of architectural styles.
• Versatile Use of Space- The flat surface of a flat roof extension offers versatility in terms of its use. It can be transformed into a rooftop terrace, outdoor living area, garden, or even an additional floor for living space or a rooftop garden.
• Energy Efficiency- Flat roof extensions can incorporate insulation and green roofing options, making them energy-efficient and environmentally friendly. They can be designed to accommodate solar panels or green roofs, helping to reduce energy consumption and contribute to sustainable living.
• Maintenance and Ease of Access- Flat roofs are generally easier to access and maintain compared to pitched roofs. They provide a safer and more convenient environment for maintenance, repairs, and the installation of equipment such as HVAC systems or solar panels.
• Natural Light- Flat roofs are ideally suited for installing roof lights (including roof lanterns and pyramid roof lights), that bring in an abundance of natural light while transforming the living area into a brighter and more open space.
