The Land Use Committee is having a meeting to hear from the developer of the Orr Block tonight at City Hall. This is the 4th meeting. Developer Robert Korff has purchased almost 3 acres at the intersection of Washington & Walnut and plans to build a 6 story mixed-use building with 150 apartments, stores, offices and 1 restaurant. You guys — this is the block that currently houses Karoun Restaurant, Boston Ballet School & Newtonville Camera.
