JCJ Architecture will expand its offices in Boston, New York and San Diego, and has added a new design principal in Boston.

The firm said the expansion is in response to growing demand, particularly in the hospitality, education and civic sectors. The firm experienced a 64 percent increase in project work compared to the same time last year, according to a statement.

"As the market edges toward recovery, JCJ is now perfectly positioned to serve our clients as they move projects from the discovery to execution phase in an economic climate of growing consumer optimism and improving credit markets," said Peter Stevens, JCJ’s president, in a statement. "Our hiring strategy and new offices in Boston, New York and San Diego will serve as our national benchmark to inspire greater collaboration, innovation and creativity to drive industry-leading design for our clients in all sectors in which we work."

In Boston, Richard Friedson will be added as a design principal. JCJ’s new open plan offices are intended to reduce the firm’s total footprint – and occupancy costs – without sacrificing productivity.  In Boston, the firm relocated to a loft at 319 A St. from 330 Congress St.
