About Us | Mackellar Schwerdt Architects

About Us

Mackellar Schwerdt Architects began with the integration of two long-established practices: RN Mackellar & Partners (formed in Newcastle Upon Tyne in 1874 as Cackett and Burns Dick) and John Schwerdt (formed in Lewes in 1954). For over 70 years, the practice has been led from offices based in the centre of Lewes, with successive generations of partners carrying forward the practice name. The partnership of Andrew Goodwin, Steven George and Stephen Dryburgh, continues the tradition.

The Practice moved into its current Lyell House offices in 2024. 

The practice's work is supported by former Partner Stephen Kemp, acting as a Consultant, who brings a wealth of knowledge and technical expertise to aid the practice in achieving the best for all of its clients.
