If you are gradually outgrowing your home, maybe its because you need another bedroom or another downstairs living area to use as an office or kids playroom, do you sell your home and move to a large house or do you upgrade your existing property adding value as you do. If you have the land to build onto, this is a great way of creating the extra space you need with out the hassle of moving home.

Over the years we have provided beautiful extra living space to numerous customers from loft conversion, kitchen extensions, sunrooms, orangeries, garage conversions and even an spa room with swimming pool! There are so many options available to improve your existing surroundings and all can be designed and tailored to suit your needs specifically.

Obviously there are rules and regulations set by your local authority when building onto an existing property but we have provided a link below for you to check out the current requirements.
