If you wish to increase the space in your property, we specialise in building home extensions and basement or loft conversions. 

Houses come in all shapes and sizes and we can help you tailor the perfect extension that will give you everything you need.

Our builders will assist you through the designing and planning and help you put your ideas to paper. Once you’re happy with everything and all preliminary work has been completed, our team of builders, joiners and electricians will get to work. We’ll leave you with a new room that is comfortable, functional and spacious.
