Innovative Extensions Crafted with Exceptional Architecture

Our West London architects create smart, sustainable extensions that suit your space perfectly.

Wraparound

We specialise in wrap-around extensions. This is a popular way to expand and transform properties. This extension combines a rear and side addition. It creates an L-shape that expands ground-floor space. This is ideal for open-plan kitchens, living spaces, or adaptable rooms that fit modern lifestyles. We handle everything from design and planning permission to construction.

Single Storey

A single-storey extension can really boost space in your West London property. It can be added to the back or side of the property. This addition offers more space for a modern kitchen, a living area, or a home office. This extension improves the flow inside and makes the property more practical. Our architectural team makes it easy for you to get great results that suit your property.

Multi Storey

A multi-storey extension in West London can provide a lot of space. You can use it for extra bedrooms, bigger living areas, or more bathrooms. Building up on your property lets you make the most of it without losing any garden space. We take care of everything. This includes planning, permissions, and construction. We ensure your extension fits well with the current architecture.

Side Return

A side return extension utilises the unused space beside your home. You often find this addon in Victorian and Edwardian buildings in West London. Clients can extend into this narrow area to make a wider, open-plan kitchen. This change will let in more natural light. Our architects are experts in side return extensions. These designs boost functionality and add to the property’s value.

Rear Extension

A rear extension expands the back of your property. This gives you room for an open-plan kitchen, a larger dining area, or a more spacious living room. This is ideal for clients looking to improve their ground floor. These extensions boost natural light and link indoor and outdoor spaces smoothly. We create rear extensions that match your home’s style. They also boost efficiency and value.
