Six projects, totaling $224 million, won approval from the Boston Redevelopment Authority Thursday.
The biggest is a new auditorium at Harvard Business School in Allston. The new $171 million Klarman Hall will feature a 1,000-seat auditorium and new space for conferences and other Business School events. A second phase next door will come later.
The BRA also approved a $20 million, 127-room loft-style hotel in a former industrial building at 175 Orleans Street in East Boston, and a $22.9 million renovation of the historic Boston Young Men's Christian Union building at 48 Boylston St. in Chinatown into 46 affordable apartment units.
