Complete design and build service for home extensions in Oxfordshire

Extension with sky light and patio doors

When you need the extra space at home but don’t want the upheaval of moving to a new house; Andy Glass Windows can help. We offer a complete design and build service to homeowners across Oxfordshire. From planning and design to building and installation, the team at Andy Glass Windows are one of the most reputable extension builders in Oxford.

Whatever type of extension you require, we have the skills and experience to meet your demands. When you want to extend outwards from your home’s kitchen or dining room, we can build the perfect small single storey extension for you. If you want to make the most of your existing unused space, we undertake garage and loft conversions which can be used as an extended living area, extra bedroom, or even an extra bathroom or shower room.

Professional extensions from planning to installation

A high quality home extension won’t just provide an extended living area; it will transform the entire layout of your home. Home extensions add value to your home and provide comfort by raising living standards.

If you’re concerned about planning permission complications, you’re in safe hands. At Andy Glass Windows, we will liaise with the local council’s planning department and complete all necessary paper work on your behalf. We will draw up and submit designs and applications, so your home extension will be truly hassle free.

Our home extension service is comprehensive. Alongside all the design and planning, we complete the entire build. We directly employ a team of bricklayers, plumbers, and electricians, and of course window installers to ensure your house extension fulfils all your specifications.

A range of windows and doors that provide the perfect finishing touch

You can choose the windows and doors you want for your new extension, from our full product range. From French doors that gracefully open up your home to the outside to tilt and turn windows that provide varying levels of ventilation, there’s no limit on the number of ways you can customise your new extension from Andy Glass all thanks to our complete design and build service.

Merry Christmas

"Prices were excellent..."

D Keegan, Oxford

After speaking with many traders, we went with Andy Glass Windows because they didn't try to give us the hard sell and because their prices were excellent. When they came to install, the 2 men were really careful, clean and very nice.

Merry Christmas

"Very professional..."

S Moss, Witney

From start to finish Andy Glass Windows were very professional, knowledgeable and there was no pressure selling. The surveyor was very thorough. The installers were prompt, polite, and did a very professional job installing our composite doors.

Merry Christmas

"Result is excellent..."

B Kirk, Cumnor

We were looking for a window product to compliment the renovation of our new home and Andy Glass Windows understood exactly what we were looking for and provided the solution with timber effect flush fitting windows. The process from ordering through to completion was very smooth and the finished result is excellent.
