The bad times are not over yet. Citing the troubled economy, Group Goetz Architects confirmed today that the Washington, D.C.–based firm will close its doors on May 25.

The Georgetown firm recently designed the offices of Foley and Lardner LLP in Washington, adding a 30,000-square-foot conference center at the top of the building at 3000 K Street NW. The interiors firm also designed celebrity chef Michel Richard’s new outpost in Tyson’s Corner, called Michel. These projects and others—including the Ansel Adams Gallery at the Wilderness Society—garnered broad praise from the press. The firm’s LEED Platinum–certified offices were featured in Architect’s 2009 Fall Product Spec Guide.

So it came as a surprise today that Lewis Goetz, AIA, founding principal and CEO, confirmed today with the Washington Business Journal that GGA was going under. Among the staff who will lose their employment with GGA are the firm’s three principals, five associate principals, and five associates. According to the report, the IRS filed a $119,743 tax lien against GGA in March.
