Building a single storey extension is the perfect way to create extra living space in your home, and might allow you to expand an existing small kitchen into a kitchen dining and living space. It might also give you the extra space to add a utility room, a cloakroom or boot room. In other words, a single storey extension will allow you to transform the downstairs of your home to better suit your lifestyle.
Building this type of extension is also the perfect opportunity to get more natural light into interiors with the addition of rooflights and much sought after bi-fold doors. They are a good alternative to moving house, too – just think of the savings you’ll make in fees like moving van hire and stamp duty alone.
