House Extensions Surrey – Seven Hills Developments

At Seven Hills Developments, we specialise in designing and building high-quality house extensions across Surrey. A home extension is the perfect way to create extra living space without the hassle of moving. Whether you need a larger kitchen, an extra bedroom, a home office, or a bright open-plan living area, we deliver bespoke solutions tailored to your lifestyle.

Many house extensions can be carried out under Permitted Development Rights, meaning planning permission is not always required.

The most popular type of extension, a single-storey rear or side extension is ideal for creating spacious kitchens, dining areas, or family rooms filled with natural light.

A two-storey extension adds significant space both upstairs and downstairs, perfect for growing families who want more bedrooms, bathrooms, and living space.

Side Return Extensions Surrey

Transform unused side alley space into a stylish side return extension, commonly used in terraced homes to expand kitchens and create open-plan living areas.
