What makes Wimbledon special?

Home to leagues and championships, theatres and retail attractions, the district of Wimbledon has gained recognition as both an affluent neighbourhood and a popular commercial centre in the London borough of Merton. The Wimbledon village is flanked with large, detached houses in unique architectural styles – Georgian, Gothic, Victorian, Classical – resulting in a neighbourhood famous for its quality and diversity of architecture, rather than uniformity.

Many residents who move to Wimbledon find it so appealing that they rarely consider relocating in the future, contributing to its lasting popularity. Wimbledon offers the best of both worlds—village charm combined with convenient access to various amenities. Its close proximity to London makes it an ideal choice for those who want the benefits of city life without living in a typical urban environment, making it a perfect blend of village and city living.

Extension Architecture, in its 16 years of experience, is especially lucky to have had the privilege to contribute to the exquisite neighbourhood with its services and expertise. We’ve worked on new build, loft conversions, house extension, kitchen extension projects and dealt with over 110 applications in Wimbledon alone. As architects in Wimbledon, Extension Architecture have successfully completed several projects in Wimbledon including projects of varying complexity along Camelot Close, Hamilton Road, Arthur Road, Walpole Road and Colonne Road to name a very few.

Our Experience in Wimbledon

In Wimbledon, an affluent suburb with a largely well-established community, extensions and refurbishments are the most sought-after projects among homeowners. This reflects their interest in not only increasing their property’s value but also improving the comfort and functionality of their living spaces. As a result, architecture planning services and interior designers in Wimbledon are also in high demand. 

Wimbledon Park is one of the many conservation areas in the London Borough of Merton. Extension Architecture has extensive experience working in Article 4 areas or on designated land. Often homeowners often hope to go down the Permitted Development route thinking it will be much easier, however, this is not always the case.

All residential and commercial projects in Wimbledon come with its own unique set of requirements and challenges, which might vary depending upon the scope of the project. Our firm has had our fair share of exposure doing a variety of different projects. Read along to get an idea of our experience and accomplishments.

Our Architectural services in Wimbledon

Loft Conversion, Wimbledon

With loft conversion projects in Wimbledon, our team had to be quite determined to understand and research in-depth about the reasons for refusal of the planning application.

Our team dedicated significant effort to thoroughly research and understand the common reasons for planning application refusals.

Issues such as obstructing light, overlooking a neighbour’s property, bulky dormers, or finishes that detract from the neighbourhood’s character could lead to potential rejections and a challenging application process.

By identifying these potential hurdles early on, we were able to address them proactively, ensuring a smooth process while preserving the client’s vision

New- build and Basement Conversion, Wimbledon

In contrast, new build and home extension projects in Wimbledon have proven to be exciting and fun for Extension Architecture. Tucked behind Wimbledon in the affluent area of Parkside, lies one such particularly exciting project  of our firm, completed back in 2017, which involved converting a single detached house into two semi-detached properties. For years, our client was advised by three different architecture firms to pursue a two-storey side and front extension.

However, Eugene Kim, the principal at Extension Architecture, proposed a different approach. By leveraging the 6-metre space on the property, Kim saw an opportunity to unlock the project’s innovative potential. His vision aimed not only to enhance the home’s value, but also to achieve the modern transformation the client desired.

The director’s vision translated into reality by not only doubling the value of the home, but was also the first project on the road to be semi-detached and undergo a basement conversion / addition.

Despite various hurdles, and involvement of lengthy procedures including pre-planning, flood risk assessment, construction method statement, topological survey, arboricultural survey and much more, Extension Architecture went above and beyond to bring the client’s vision to life through careful planning, design and personal interaction with the client to ensure all the design elements fit the bill.

House Extension, Wimbledon

House Extension, Wimbledon

Like all other projects, undertaking house extensions in Wimbledon is exactly not a bed of roses! However, with our years of experience, we have mastered the right way to get the planning applications approved.

Living in an age of technology, most homeowners want to have a modernistic approach towards their extension which sometimes might not sit right with the council’s guidelines of respecting the neighbourhood character.

With the design knowledge of our planning team, we can collaborate together and amalgamate the existing unique architectural style of your house with a newer approach to achieve your desired vision while obeying the planning permission rules.

Other Projects in Wimbledon

Extension Architecture looks at expanding its portfolio in Wimbledon. While we have had the opportunity to provide our expertise in the area through a range of projects, we currently are dealing with another 8-10 projects under the same council. To gather detailed insight on our services, we’d love you to go through our Copse Hill Loft Conversion, New Build Project, Wimbledon and House Extension, Wimbledon.

Most of northern Wimbledon consists of conservation areas, which can be a tricky and tedious task to deal with! With our experience working in such areas, we are well-versed in understanding the right way to carry out developments without compromising on the Wimbledon area’s special character.

Our multidisciplinary team of seasoned professionals and dedicated designers has successfully completed thousands of planning applications across the UK.

  • 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.

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.
