What makes Wandsworth Special?

Wandsworth is of course a desirable place to be, close to the centre of London with a mix of high streets and local parks around the neighbouring areas. The local authority in Wandsworth is rightfully strict about regulations and conservation areas which protect historically and architecturally significant buildings.

Even if your property is not located in these designated areas, it doesn't stop the local authorities from carefully considering the proposed changes. As experienced architects in Wandsworth, we understand Wandsworth planning regulations and can help navigate your project to achieve its objectives and respect the unique heritage of the area.

Our Experience in Wandsworth

Based in the heart of Wandsworth, Extension Architecture has developed an in-depth understanding of the local area. Our strong referral network, built through successful collaborations, often leads us to work on multiple projects within the same street which contributes to our continued knowledge of planning policies and building typologies.

We offer a range of services including house extensions, loft conversions, and renovations for property owners alike looking to boost their property value and enhance their livable space.

Our Architectural services in Wandsworth

Loft Conversion, Wandsworth

Loft conversions are a popular option for Wandsworth homeowners looking to increase the value of their property by adding an extra bedroom or private living area.

Wandsworth builders or homeowners have to go through a number of restrictions, particularly if the property is in a conservation area or a listed building.

Planning permission may be required, if the alteration involves major changes to the roof or involves dormer windows. Additionally, building codes must be followed, ensuring safety and construction integrity.

By adhering to the code, builders or homeowners can create stunning rooftop or lofts that blend seamlessly with the existing home and meet Wandsworth’s regulations.

What makes us Unique?


Our team of experienced professionals and creative architects sets us apart as the go-to choice for planning and structural consultations in Wandsworth. With a solid track record of handling hundreds of planning applications, we’re committed to delivering spaces that not only meet but exceed expectations.
  • One-Stop Solution
Our firm provides a comprehensive range of services under one roof, from planning and architectural design to intricate interior and immersive design, and expertly manages the complexities of the construction process. Our extensive experience and proven track record are a testament to our success in delivering projects of various scales and budgets, from small home extensions to large new builds, for a diverse clientele. Our multidisciplinary team of seasoned professionals and dedicated designers has successfully completed thousands of planning applications across the UK. We pride ourselves on transforming properties into dream spaces while maintaining a strong commitment to exceptional design and client satisfaction.
  • In-house Structural Engineer
What truly sets us apart in this competitive market is our in-house structural engineer—an advantage that only 1 in 20 firms can offer. This is crucial, as significant time is often lost consulting multiple specialists, which can lead to additional costs. With a structural engineer on our team, we ensure a fully collaborative and seamless design-build process, minimising contingencies and preventing design inaccuracies.
  • Turkey Approach
We provide support throughout the entire building process, embracing a ‘turnkey approach’ to ensure a smooth and efficient project from start to finish. Additionally, we assist in reducing build costs by aiding in the procurement of all internal fit-outs, including sanitaryware, kitchens, and more.
  • Interior Design + Architecture
Our team includes interior designers who work closely with the clients, especially the ‘ladies’ of the house to curate the dream spaces tailored to their requirements. These processes include fun yet crucial processes like selecting wall finishes, colour schemes, soft furnishings, flooring, and layout. Having architects and interior designers under one roof allows for less contingencies and offers a much more comfortable experience to our clients.
