Both practices already belong to French multinational architecture and engineering giant Egis’s 10N collection of architectural studios, but the merger, announced today (13 January), means that 12 global offices will nowcome under the WW+P brand. Other Egis practices include London, Hong Kong, and San Francisco-based 10 Design, San Francisco-based SB Architects and Middle East-based U+A. WW+P’s staff numbers have more than doubled following the merger – from 168 a year ago up to 410.
