You thought there was enough drama in the streets of Allston already? The developers of 9-23 Griggs Street are offering a theater as one of the amenities. Residents will also benefit from the usual fitness center and roof deck. Mount Vernon Company, the developer, has also been acquiring some other property in the area, most recently 83 rental apartments at 74-86 Brainerd Road. And this Thursday they will be at the Brighton Allston Improvement Association to talk about a proposal for 79 units at 66 Brainerd Road. They have a lot going on in a small sliver along the Brookline border, it will be interesting to see what else they want to do.
