Meet the founder
Meet Mark Howorth, an award-winning interior designer, who is considered by many to be one of the best interior designers in London.
Mark started his career living and working in Los Angeles designing high end residential projects throughout LA and Southern California. He then moved back to London and founded Callender Howorth in 1997. Callender Howorth has grown since then to design and manage projects throughout the UK, the South of France and Manhattan. The core design team, based in London, covers all aspects of Interior and Architectural Design and Project Management.
Meet some Clients
Devonshire Mews, London, was a breathtaking project that echoed the inspirations of the clients in their own personal space. Callender Howorth worked with the owners on every-last exquisite detail.
Many visions were fulfilled during the completion of this non-archetypal London abode. The team worked with the clients to provide a sense of a charismatic living quarter. Each client’s wishes are different in every plan, our aim is to bring the client’s idealistic qualities to life, making each result profound and thoughtful.
We project managed this property in order to bring a utopian finish and detailed format to suit the client’s principle conceptions from start to finish.
