House Extensions in Cwmbran
Add Valuable Space and Increase the Potential of Your South Wales Home With a High-Quality Extension Tailored to Your Lifestyle
House extensions are a popular solution for anyone seeking to enhance living space without relocating. These additions can range from simple single-room extensions at the side of your home to more complex multi-storey projects tailored to meet various needs, such as additional bedrooms, home offices, or social areas. Once completed, they increase your property’s functional space and significantly boost its market value.
While some can be constructed under permitted development without planning permission, others require approval from your local authority. The team at Balaam Ltd is happy to help with this process, ensuring strict compliance with all regulations and a perfect blend of modern construction and existing architecture.
Please get in touch with our building contractors for more information regarding our house extensions and other building services in Cwmbran and the surrounding areas. We complete every aspect of the project from design to completion, including structural alterations, new kitchen and bathroom installations, and decoration.
Types of House Extensions
Multi-Storey House Extensions

Double-storey extensions add significant space and value to any home. They’re ideal for growing families or creating extra bedrooms, home offices, and play areas. They often blend seamlessly with existing architecture, enhancing kerb appeal and market value. Our meticulous planning and budgeting ensure structural integrity and strict compliance with local regulations.
Side-Return Extensions

Side-return extensions reclaim unused space beside a property, transforming narrow passages into new kitchens, dining areas, or bespoke home offices. They’re perfect for urban homes in and around Cwmbran, where space is premium. They add value and square footage without affecting the garden. Plus, these house extensions give your home a stylish upgrade.
Rear-Facing Extensions

These renovations blend contemporary design with practical space solutions, creating modern interiors for our clients. They enhance functionality by expanding living space and accommodating growing families or new lifestyles. More natural light and open layouts make home life considerably more spacious, with bespoke layouts tailored to your needs.
Wraparound Extensions

Wraparound house extensions will blend seamlessly with your home, extending space without breaking its flow. Uniting side-return and rear-facing additions, they wrap around corners, making room for spacious kitchens and open-plan living areas. They transform houses into dream homes, from modern glass extensions to traditional designs.
Over-Structure Extensions

Extensions added above existing garages or single-storey dwellings are popular for maximising space without expanding your home’s footprint. Like any other renovation, they provide additional rooms, such as bedrooms or offices, enhancing property value and functionality. However, the building process is a little more challenging as we must ensure the existing structure can bear the weight of the new construction.
Why House Extensions Make Sense
A house extension is one of the most effective ways to enhance your living space without the stress and cost of moving. It allows you to expand and adapt your home to meet changing needs, making room for a growing family, creating a larger kitchen-diner, or adding a quiet office away from busy living areas. At Balaam Ltd, we build stylish, functional extensions that blend seamlessly with your property’s existing design while maximising light, space, and comfort.
One of the main advantages of a house extension is its flexibility. You can choose how the new space is used and finished, from practical utility rooms to luxurious lounges or additional bedrooms with en-suite facilities. Extensions also add significant resale value, especially when professionally designed and constructed with quality materials.
Modern building techniques and energy-efficient materials mean your new space can be warm, well-insulated, and cost-effective to run. Our experienced building contractors will handle planning, design, and construction, ensuring a smooth process from start to finish. A well-planned extension will give your home the extra space it needs today and boost its appeal for years.


Will my house extension require planning permission?
It depends on the size and location of the extension. Many single-storey rear extensions fall under permitted development, but larger rear and double-storey extensions often need approval. We can advise on regulations and manage applications on your behalf.
How much value can a house extension add to my property?
A well-designed extension can significantly increase your home’s value, particularly when it adds functional living space like a kitchen-diner, bedroom, or home office. In many cases, homeowners see a strong return on investment when selling in the future.
Do you match the extension to the existing property?
Absolutely. We take great care to ensure the new structure complements your home in style and materials. We aim to create a seamless extension that looks like it’s always been part of the original design.
