Greig + Stephenson Architects (GSA) was formed in 1994 by directors Ken Greig and Nigel Stephenson, both of whom have more than 25 years experience as architects and designers in the international retail and property markets.

GSA offers a full architectural and design service for new-build, refurbishment and interiors projects, as well as retail branding and environmental graphics. Specialisms include concept work, retail developments at all scales, and urban regeneration schemes, particularly markets. We also have experience with leisure projects, offices, schools and civic buildings.

The GSA portfolio is Pan-European and includes projects in the UK, Ireland, France, Holland, Belgium, Germany, Italy, Spain, Poland, the Czech Republic, Estonia, Norway, Finland and Sweden.

The company is based in offices on the corner of Stoney Street, close to London Bridge tube station, Borough Market, and Southwark Cathedral.
