Choosing Your Living Space
Extensions have never been so popular. More and more householders are opting to expand their existing space, and it makes sense when you consider how inexpensive it is compared to relocating. So that you get an extension that fulfils your full set of criteria, have a read of our buyers guide.

Pick the perfect position
Where is the best position for the extension? Would you like the extension to be somewhat secluded? Is the view you get from the extension important?
Once you have a satisfactory answer to all of these questions, you can then pick a suitable roofing system and the right styles of windows and doors.
Designed for your requirements
Arguably, the important thing is the appearance of the extension. You want it to look impressive and it will certainly look like that whether you want UPVC or aluminium windows, a tiled roofing system or skylights.

Accessorise your space
Pretty much anything is achievable and you can see all of your big ideas brought to life via our state-of-the-art 3D software. Use of this technology enables you to see your extension like you never could have imagined.
You will find it difficult knowing where to start with your extension as we have so many possibilities in terms of roofing options (including traditional tile or slate and modern composite) and a fine selection of window and door styles.
