House Extensions
Home extensions are an excellent way to enhance your property, adding space, functionality, and long-term value. If you’re searching for extensions near you in Bristol, our team at Britannia Windows designs and installs high-quality home extension solutions tailored to your lifestyle.
Whether you’re planning a spacious kitchen extension, a bright glass room extension, or a practical single storey extension, extensions allow you to customise your home to suit your needs perfectly. From modern hup systems and energy-efficient sip extensions to beautifully crafted house extensions, we offer a wide range of options to help transform your property into your ideal living space.
There are many types of house extensions available, each offering its own advantages depending on how you want to use the space. Our outdoor living solutions are extremely versatile and can function as stylish kitchen extension areas, open-plan family rooms, or relaxing garden-facing spaces. Whether you choose a contemporary glass room extension or a solid, insulated home extension, our expert team ensures a seamless design that complements your home and enhances your everyday living in Bristol.
Conservatory & Orangery Extensions
Adding an orangery extension or conservatory is a great way to increase space, natural light, and value in your home. Whether you prefer a modern glass conservatory or a more traditional lean-to conservatory, there are plenty of styles to suit your property. These versatile spaces create a seamless connection between your home and garden, providing a bright and comfortable area that can be used all year round.
When planning your project, it’s important to consider the overall cost of a conservatory, which can vary depending on the size, design, materials, and glazing options you choose. A simple lean-to conservatory is often a more cost-effective option, while larger or more bespoke designs such as an orangery extension may require a higher investment. With the right design and installation, both options offer excellent energy efficiency, durability, and long-term value for your home.
At Britannia Windows, we offer a range of bespoke solutions to suit your needs and budget. From initial design through to installation, our team will guide you in choosing the ideal conservatory or orangery extension for your home.
Living Space Designs
Our living spaces come in a wide variety of designs, including one wall, two walls, three walls, low walls, and many other configurations, allowing each home extension to be tailored precisely to your property. This flexibility makes our house extensions ideal for homeowners looking to maximise space while maintaining a seamless connection with their existing home.
Glass extensions are a breathtaking way to bring the outdoors in, flooding your home with natural light and offering uninterrupted garden views. A glass room extension can be used as a sunroom, dining area, or even a home office, making it a popular choice for modern living. We specialise in the design and installation of bespoke glass extensions, ensuring every single storey extension is crafted to suit your needs and personal style. We also offer Apex extensions, featuring high, pitched roofs that deliver a traditional yet timeless look while increasing headroom and creating a more open feel.
Our bespoke extensions are fully custom designed to match your exact requirements, offering far greater flexibility than standard solutions. Whether you’re planning a stylish kitchen extension, a contemporary home extension, or a light-filled glass room extension, we’ll work closely with you to bring your vision to life. With a strong focus on quality and customer satisfaction, we ensure a smooth and stress-free experience from the initial consultation through to the completed house extension.

Great job of our new front door. They couldn’t have been more helpful and even fitted earlier than originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.

Cannot recommend Britannia Windows enough! Joe & Keith, the installers were great – explained what was to be done, showed me everything I needed to know upon completion, very considerate & tidied up really nicely. Very friendly guys who are an asset to the team!!
I LOVE my new windows & door. Such an improvement.
Happy Customers
Rachel Godfrey
We have been extremely pleased with Britannia’s service. From the initial quote through to installation they were great and really easy to communicate with. We had our conservatory roof replaced and they were by far the least pushy and most competitive in terms of pricing.
We can definitely recommend their services and will likely be returning again soon for a new front door!

Fantastic job from initial phone call through to final tidy-up.
Britannia provided great advice before purchasing my new windows and fitted them to a high standard being punctual and polite throughout.
No request was a problem and I will definitely be using them again and would recommend to friends and family.

Wow a fantastic job by both sales team and fitting team.
Sam provided excellent service and answered any questions that we had. Luke, Dave, Keith and Joe did a fab job at fitting the windows and doors. Never having had anything like this done before I was a little nervous but the guys were clean and tidy and the outcome is amazing.
Would highly recommend.
