Single storey extension
Our clients wanted to build a larger kitchen that would help bring more light into their North London home. Using the best materials, our extension experts added this kitchen extension to the house's back. The Velux roof windows helped brighten the house interiors.
Double storey extension
Our client decided to build a two-storey extension. As this property in north London sits on a slope, the project architect designed a home extension with a half basement and sliding glass doors. Our builders, who have years of experience in this field, completed the building process following the plans.
Single Storey House and Kitchen Extensions
A single-storey extension is a popular type of home improvement project, as it connects the house with the garden. There are three kinds of one storey extensions: rear, side return and wrap-around. (pictured). While most single storey rear and side return house extensions qualify under the Permitted Development, a wrap around extension requires Planning Permission. Our North London house extension builders could help you add space to create a large open-plan kitchen while making a connection with your back garden, a bright lounge area with a fireplace, or a gym.
Roof and skylights
A double-storey house extension might be cost-effective than a single storey, as the roof and the foundations tend to be the expensive parts of the build overall. Our north London builders, who have years of experience, could add a two storey extension to the back or the side of your property. In order to comply with regulations, two-storey side extensions need to have a pitched roof similar in design to the existing one. You could go for a kitchen extension, and add an extra bedroom, a playroom, or an office.
