A national architectural firm that has worked with the Seneca Nation of Indians on its casino designs is opening a permanent office in Buffalo, taking up space in Buffalo’s tallest office building.

SOSH Architects will occupy just under 3,000 square feet of space on the 27th floor of One Seneca Tower, under a one-year lease, according to Richard Schechter, the court-appointed “receiver” for the 38-story building. Schechter, also a commercial real estate broker with Pyramid Brokerage Co. of Buffalo, is responsible for overseeing the operations and maintenance of the 850,000-square-foot tower while it winds through the foreclosure process.

SOSH’s new office will be managed by local architect Russell E. Bennett Jr., and will employ six to eight professional and support staff, with plans to grow that number to 12 to 16 within a year. The firm was the designer of the original Seneca Buffalo Creek Casino and Hotel project, as well as the recent renovations to the Seneca Niagara Casino in Niagara Falls.

Founded in 1979, SOSH is an architectural and planning firm specializing in the hospitality, entertainment, retail, civic and education fields. The firm has offices in New York City and Atlantic City.
