Our extensions process includes:
Whether it’s a contemporary addition or a traditional extension, we are committed to delivering a space that enhances your lifestyle and adds value to your home.
A rear extension is a popular choice for creating additional space while maintaining the character of your home. These extensions often open up the back of the property, blending indoor and outdoor spaces. Whether you’re planning a larger kitchen-diner, a family room, or a seamless connection to your garden, our team ensures the design complements your home’s architecture and enhances its functionality.
Combine the benefits of both side and rear extensions with a wrap-around design. These “L-shaped” extensions maximise space and are ideal for creating open-plan living areas, expanding kitchens, or adding multiple rooms. Our team works closely with you to ensure the new space fits your lifestyle while maintaining structural integrity and aesthetic appeal.
Expand your home’s footprint with a single-storey extension. This versatile option can be used to create a new living space, home office, or utility room. Whether you want a contemporary design with large windows or a more traditional look, we bring your vision to life with expert craftsmanship and premium materials.
Preserve the charm and heritage of your period home while modernising key elements for comfort and functionality.
