Cowan Architects is an established practice offering innovative design solutions coupled with a high level of personal service from experienced and enthusiastic staff. We work closely with our clients to ensure their design requirements are met and take pride in our professional, practical and personal approach. The Practice was established by the current Chairman, David Cowan, in 1983 and is based in East Grinstead, West Sussex. Whilst we predominantly serve the South East and Home Counties, our Expert Witness work covers the whole of the UK and Ireland. We have significant experience across many sectors, including developer residential, healthcare, home-owner residential, conservation, commercial and industrial with project values ranging from £100k to £10m. A proven track record for residential and healthcare work has resulted in an additional speciality, with the practice being recognised as one of the leading architectural firms for inclusive design. A product of this reputation is that 6 of our Architects now act as Expert Witnesses on disability needs in High Court cases.

As well as being registered Chartered Architects we are also AECB and Pasivehaus Trust members and listed on the “Green Register”. We contribute to The Architects for Health Executive Committee and are registered as Client Design advisors for Education and Master Planning, as well as having approved architects on a number of Diocese Advisory Committees (DAC) including: London, Rochester, Winchester, Chichester & Portsmouth .
