Before listing all the largest and best firms in , we should understand why we can consider London as the architecture capital city in the World. Quite all the with their world's foremost architects, interior designers, engineers, and urban planners have their headquarters or at least a representative office in London.

During the Second World War, many parts of London were bombed. In an effort to rebuilt it quickly and efficiently, high rise blocks were introduced to London. The capital has long served as a canvas for pioneering architects from all over the world. It is home to a variety of bold buildings from brutalist and art-deco estates to the modern-day glass architectures.

Although not all of them are based there, London has now the highest concentration of architectural practices of any city in the world and is regarded as a global hub of architectural thinking and teaching: the United Kingdom is home to three out of the top 10 universities for architecture in the world and London is the ideal meeting place between East and West of the World.


Amongst the largest architectural companies headquartered in London you will find:

Foster + Partners

The largest architecture firms in the UK is Foster + Partners, a global studio for architecture, urbanism and design, rooted in sustainability. The practice was founded over fifty years ago in 1967 by Norman Foster. Since then, he and the team around him have established an international practice with a worldwide reputation for thoughtful and pioneering design, working as a single studio that is both ethnically and culturally diverse. The studio integrates the skills of architecture with engineering, both structural and environmental, urbanism, interior and industrial design, model and film making, aeronautics and many more – their collegiate working environment is similar to a compact university. These diverse skills make Foster + Partners capable of tackling a wide range of projects, particularly those of considerable complexity and scale. Design is at the core of everything that they do.
