Plan the furniture, daylight and garden connection together
A kitchen-dining space, family room and home office each need a different balance of wall space, light and privacy. We discuss where furniture will go, how doors open and how the extension connects to the rooms behind it.
Foundations, drainage, the opening into the house and site access shape the project as much as the visible finishes. The survey and design process help establish the work required and which approvals need to be considered.
What is included in an extension quotation?
Look for a clear scope covering the agreed groundworks, walls, roof, glazing, external finish, plastering and services. Kitchen fitting, flooring, decoration and other work should be identified as included or excluded. We talk through these details so you can budget around a defined project.

We are extremely happy with our new windows. We’ve had lots of comments from friends and neighbours on how lovely the windows look. They gave the house a complete makeover.
Richard and team are very professional and went the extra mile to help us resolve our issues. Thank you!
We will be using this company again for the front porch and the remaining of the windows.

We had two replacement windows with Spectrum. Both the ordering and fitting were simple and efficient. It took 4 weeks from ordering to fitting. The team that fitted the windows were friendly but professional. We would recommend this company.

Richard and the team were wonderful with our tricky small extension/garden room. We had 3 different building companies tell us we had no options to extend. Richard was solutions focused and listened carefully to understand what we wanted to achieve. He used reputable and high quality subcontractors for parts of the build and we are thrilled with the results. While we've only gained an extra 15m2 on our downstairs, it's completely transformed how we use the space as a family and means we can finally entertain.

We couldn’t be happier with the service from Spectrum Glazing. Rich was really great in helping us achieve exactly the look we were going for and the fitters, Phil & Mark were great from start to finish, working skillfully throughout the day (and in the pouring rain!) they left the house clean, having used dust sheets everywhere and vacuumed once the job was done. The new windows look fantastic and the finish is impeccable. Highly recommended for anyone looking for a stress-free experience.

We are very happy with our new doors. Everything was smooth and easy, with great communication throughout the process, and the installation only took a few hours. They also cleaned up and took away the old doors, which was nice and one less thing to worry about. Would definitely recommend this local business!

Absolutely chuffed with our new front door from Spectrum. It has made such a huge difference to our entrance way, and no draft at all on the inside. The whole process was smooth and easy and the new door was installed within 6 weeks of ordering, even with the Christmas period. Such good value for money as well with the quality and experience. Would highly recommend.

Spectrum recently replaced all the windows in my house and built a Hup extension to the property. They have been entirely excellent throughout, with all work carried out on schedule, on budget and to an excellent standard. I would definitely use them again, and have no hesitation in giving them my strongest recommendation.

Firstly, I cannot praise Spectrum Glazing Limited enough for the quality and attention to detail of the fitters tasked with our installation. They went above and beyond my expectations. They were polite, tidy and efficient and did the perfect job.
The product as you can see from the images, look amazing and really enhance our kitchen. The door flow easily when opening and closing, the handles make this operation simple and the locking is also simple.
The lead time for the product was also much shorter than other companies had quoted.
I am very pleased with the doors and would recommend them and the service that I received. An excellent product, and a happy customer.

Your questions answered
Can you help me compare a conservatory and an extension?
Yes. We discuss the intended use, wall-to-glass balance, roof type and connection to your home, then compare the options and their scope.
Can I use a tiled roof on a new extension?
Yes. Explore our Ultraroof extension page and designer to discuss suitable roof forms, glazed sections and finishes for a new build.
Do you work with existing conservatories?
We can assess a refurbishment, conversion or rebuild. Existing foundations and frames can only be retained where they are suitable for the proposed design.
What should I bring to the first discussion?
Photographs, approximate dimensions, your postcode and a simple list of what the new room needs to do are a useful start. Existing drawings are helpful if you have them.
