“GreigĀ and Stephenson Architect’s primary business focuses on retail and market led developments, refurbishments, urban regeneration schemes and masterplanning design.”

GSA has particular specialism in market redevelopment, both nationally and internationally. The practice is passionate about the wider social and economic regenerative qualities of markets, as well as the key role the associated design of the individual’s business can have on the success of projects.

Our extensive retail experience provides strong design principles for the successful implementation of contemporary trading environments; while experience in both the macro and micro detail is strengthened by our engagement with the consultation process, delivering market designs that work both operationally and economically for the client and wider stakeholders.

Our design principles are rooted in a commitment to sustainable design and we believe the regeneration and adaptive reuse of the existing built environment is a key factor in prolonging and renewing the embodied social and environmental energy of spaces and places.
