What makes Beckenham special?

Beckenham is actually one of the places that has a rich history and great atmosphere that is loved by many people. A city famous for its architecture, Victorian and Edwardian style houses on avenues filled with trees are common. Among such dwellings, which have always been popular, one can find relatively compact homes with 1930s semi- and terraced structures.

The history of Beckenham is easily noticeable when walking down the streets as one can find such landmarks as the George Inn, built in the 17th century, and the war memorial erected in 1921. It is a place where people have long tenure – many families live there for generations, and when they need a larger house, they expand instead of moving elsewhere. Beckenham has beautiful parks, great schools, and a friendly community, and it is so much more than just a place to call home.

Our Experience in Beckenham

Extension Architecture is a team of architects that carry a strong connection with the Beckenham architectural environment. We are not just designers but build spaces that add value to your way of life. From a small home addition up to a build of a new house, the projects shine through but still maintain the essence of Bromley borough.

Having a thorough knowledge of the planning permissions of the council and various types of architecture, we design solutions for the corresponding needs of the community. As Beckenham architects our completed projects are: 6 Amesbury Road, 29 Bromley Common, 90 Farnaby Road, 45 Brangbourne Road.

How we work in this area

Loft conversion, Beckenham

Beckenham is becoming one of the most sought after places to live due to the quality of its schools, and the friendly people who live there. However, due to the slow progress in the housing market, most of the people in the town of Beckenham look upwards towards their roofs.

Loft conversions are also being sought out for the versatility it provides to gain space on the upper floor while not compromising garden areas and are commonly built from timber or steel frames.

However, planning in Bromley Council can be quite challenging especially if your house is located in a conservation area. That’s where Extension Architecture comes into the picture. We pride ourselves in converting these spaces to classy, stylish and contemporary lofts that can harmonise with the rest of your house.

We are here for you to guide you from getting into trouble such as those relating to the Party Wall Act and not only help you design a beautiful loft conversion in Beckenham but also increase the usefulness of your house and its value.

What makes us Unique?


Extension Architecture has grown to be among the top architectural designing companies based in Beckenham with distinctive, efficient and durable designs. Right from the sketching of ideas to the final polished documents, we ensure you go through a smooth experience.
  • Planning Applications with Bromley Council
Any fragile piece of land, be it in a conservation area or in the green belt zone? Do not let this be a cause to deter you from building the house of your dreams. We are experts at contemporary designs that retain the historic appeal of your home as well as its potential. This means that our mission is to help make your homes not just aesthetically appealing but also make homes to last for a century or more.
  • Building Regulation Drawings
They say the devils in the details, and in most cases,this is true. The more information you supply for construction, the better. We prepare all documentation for RIBA Stages 4-7 to ensure you have all the specifications and details you need for builders to construct your home.
  • In-House Structural Engineer
One of our biggest competitive advantages is that we have a structural engineer as a member of the firm, whereas most of our competitors strictly provide architectural services. This integration helps to save time and costs, while still maintaining proper collaboration between the architects and the builders. From the onset to the delivery of the final product, our clients can always engage us for quick service with little to no complications.
