Why Choose Extensions Over Moving?
Many homeowners in Cheltenham face the question: extend or move? For most, a well-designed house extension in Cheltenham offers the perfect solution. You keep the location you love, avoid the stress and expense of moving, and create a home perfectly tailored to your needs. Our extensions typically add significant value to properties across Gloucestershire, often exceeding the cost of construction.

From modest single-storey rear extensions to impressive double-storey additions, we have the expertise to transform your property while respecting its original character and the architectural style of your neighbourhood.
Types of House Extensions We Build
Single Storey Extensions
Perfect for creating open-plan kitchen diners or adding a garden room. Single storey extensions in Cheltenham are ideal for ground floor living space, providing natural light and easy garden access. We design these extensions to maximise space while maintaining excellent proportions.
Double Storey Extensions
Maximise your property's potential with a double storey extension. These provide substantial additional space, often including a new kitchen or dining area downstairs and extra bedrooms or a master suite above. Popular throughout Gloucestershire for their excellent value.
Side Return & Rear Extensions
Make use of every square metre of your plot. Side return extensions are particularly popular in Cheltenham's terraced properties, while rear extensions can dramatically open up your living space. We specialise in designs that flood these areas with natural light.
Wrap-Around Extensions
Combining side and rear extensions creates impressive L-shaped additions that can transform your entire ground floor. These comprehensive projects are perfect for creating stunning open-plan living spaces in Cheltenham homes.
Our Extension Design & Build Process
Every successful house extension in Cheltenham starts with careful planning and design. Our experienced team begins with a thorough consultation to understand your needs, budget, and vision. We then create detailed designs that maximise space while complementing your existing property and meeting all planning requirements in Gloucestershire.
We handle all aspects of your extension project, including planning applications, Building Regulations approval, and coordinating all trades. Our project management approach ensures your extension is completed on time and to budget, with minimal disruption to your daily life. We maintain clear communication throughout, keeping you informed at every stage.
Planning Permission & Building Regulations in Cheltenham
Understanding local planning requirements is crucial for house extensions in Cheltenham. Many extensions fall under Permitted Development rights, meaning you won't need planning permission. However, properties in conservation areas or with other restrictions may require approval. We have extensive experience navigating Gloucestershire's planning system and will advise on the requirements for your specific project.
All extensions must comply with Building Regulations, covering structural integrity, fire safety, energy efficiency, and more. Our team ensures your extension meets all requirements, liaising with Building Control on your behalf. This guarantees your new space is safe, comfortable, and adds genuine value to your Cheltenham property.
Quality Construction & Finishing
The quality of construction separates good extensions from exceptional ones. At CLG UK, we use only experienced tradespeople and premium materials. We pay particular attention to matching existing materials and architectural details, ensuring your extension looks like an original part of your home rather than an obvious addition.
Modern extensions in Cheltenham demand high energy efficiency standards. We incorporate excellent insulation, energy-efficient glazing, and modern heating systems to create comfortable spaces that are cheap to run. Our attention to detail extends to every finish, from plastering and flooring to electrical fittings and decoration.

Frequently Asked Questions About House Extensions
Do I need planning permission for an extension in Cheltenham?
Many extensions fall under permitted development rights. Single-storey rear extensions up to 4m (3m for attached properties) generally don't need permission. However, properties in conservation areas, those with previous extensions, or larger projects typically require approval from Cheltenham Borough Council. We assess your specific situation and handle all applications.
How much value does an extension add?
Well-designed extensions in Cheltenham typically add more value than their cost. Adding a bedroom can increase value by 10-15%, while quality kitchen extensions often add 5-10%. The exact figure depends on your property type, location in Gloucestershire, and quality of finish.
Can I live in my home during the extension?
Yes, most families remain in their Cheltenham homes during construction. We minimise disruption by sealing off work areas, maintaining access routes, and scheduling noisy work for daytime hours. Kitchen extensions may require temporary kitchen facilities for 1-2 weeks.
What about Building Regulations?
All extensions must comply with Building Regulations covering structure, fire safety, energy efficiency, ventilation, drainage, and electrical work. We handle all applications and coordinate inspections at key stages. You receive completion certificates for your records.
Do you handle everything including design?
Yes, we offer complete design and build services for extensions across Gloucestershire. Our team includes experienced designers who create detailed plans tailored to your property and requirements. We manage the entire project from initial concept through to completion.
