Extentions building in Leeds and Yorkshire.

Would you like to add extra space and value to your home? Hire our Leeds based company to improve your home's architectural design and maximize the space you have available with side return extensions. Find out what you need: a basement conversion or a side return kitchen extension. If you let us architect your home and make use of house extensions, you can discover what interior designers can do with space limitations. You too can have a modern kitchen, spacious and practical or you can benefit from our experience with unique house designs in other areas of your home.


We have been designing and building side return extensions since 2003 for homeowners who appreciate our quality driven approach and excellent customer service. You no longer need to find a builder who can implement your architectural design. We offer a Full Design and Build Service and all our projects are backed by a 10 Year Guarantee.


Side extensions are our specialty, but we can also offer loft conversion ideas or loft room ideas for clients looking for a one-stop-shop solution. Leeds loft conversions and modern house plans are very much needed in an overcrowded and ever-expanding city and we are very proud to be able to provide our clients with excellent solutions which improve their lifestyle. Browse our website to learn more about us and our house extensions and obtain an online quote for any idea you have to design your own house. For example, find out the extension cost you might have been thinking of!
