Luxury House Extensions
Get Your DesignsOur house extensions are habitable spaces that are versatile. This means they can be turned into a living room or an extra bathroom. The choice is entirely yours. All the designs are available with advanced double glazing, so you will get plenty of security measures to keep intruders out. What’s more, the doors are available with multi point locking systems and advanced shootbolt techniques, ensuring your family will be kept safe in the long run.
What’s more, when you choose a house extension, it is much cheaper than an extension, resulting in a cost effective build. Get a beautiful space without breaking the bank. And, you can upgrade it further with triple glazing, which can tackle the worst winds.

Book a home visitCost-Effective Extension
A conservatory is ideal because it is a cost-effective installation, providing natural light and thermal efficiency in your property. Because the conservatories are largely composed form glass, they will let in heaps of natural light in your home, ensuring you save on energy bills.
If you have children, a conservatory is great at bridging the gap between the house and the garden. It supports all types of doors from patio doors to French doors, giving you plenty of ventilation and fresh air.
And, the conservatory is great at saving space too, which is ideal if you want to sell your home. This is because a growing family will be impressed by the illusion of a bigger space. And, you will take advantage of a versatile build. Use it as a bathroom or a cinema room, perfect as a relaxing area.
Further Customisation
At Britannia, we believe you should be given free rein to customise your product in any way you like. Choose from a bespoke range of styles and colours. We have an abundance of choices for you, from Chartwell Green for a natural look, to Golden Oak. Or, choose from any RAL colour for a bespoke selection of choices.
What’s more, you can select a cornice to hide unsightly guttering. This will improve your home’s curb appeal straight away. And, the conservatory has low U values of 1.0 W/m²K, making it one of the warmest builds on the market.

I want to thank the staff at CTG Windows for doing a great job. They replaced my old windows and doors with new ones that look amazing. They were very professional, punctual, and polite. I am very impressed with their service and quality. They come highly recommended.
Paul Gualli
I am very happy with my new front door from CTG Windows. They offered me a good price, friendly service, and easy installation. They also completed the job on time and with minimal disruption. I would highly recommend them to anyone looking for a new front door in Cornwall.
David
I am very satisfied with my new windows. They have significantly reduced the wind noise and made my house much warmer. The installation team was professional, friendly, and fast. They did a great job and left no mess behind. I’ve already recommended CTG Windows to my neighbours.
Albert Steptoe
The two-man team who did this week’s work were the same ones who replaced four bedroom windows for us last year. Their names were Andy and Tony and what a brilliant pair of guys they were, great fellas to chat with, very polite, very professional, great sense of humour, and their attention to detail was absolutely great.
The finish on these last four windows was second to none, I’d have Andy and Tony back here to fit any more windows in an instant.
Mark Withecombe
I was impressed from start to finish. Communication was excellent throughout, enabling me to be kept informed of what was happening. The quality of the doors was also excellent. The price was extremely competitive. The standard of craftsmanship by the fitters was outstanding. The fitters were also, very professional, and friendly and ensured attention to detail throughout the fitting.
