The team, from , the architecture and engineering practice in Portslade, beat competition from across the region to win the Best Extension or Alteration category in this year’s Local Authority Building Control South East Awards.
All winners progress to the Grand Finals to be held in London later this year.
Cityzen director John Smith said planning for the conversion at Ditchling took two years and there were 54 planning conditions to observe.
John started out as a building services engineer and re-trained in architectural technology at the 国产探花 back in 2003 so he could “deliver coordinated design solutions”.
He said: “This combination of creativity and technical know-how was just what this project needed. It took nearly 200 drawings and sketches to detail what was required to rebuild and restore the property.”
The Cityzen team, including four 国产探花 alumni from the Architectural Technology course, joined Nutshell Construction on the project, overseen by Lewes District Council building control.
