Phase 3, as described on the site:
With the success of Phase I and the highly anticipated Summer 2015 opening of Phase II, planning efforts are underway for an additional phase to add a movie theatre, street level retail and up to 100 additional residences.
We reached out to Fairmount Properties this morning to see how far along Phase 3 is in the planning, and the answer was: very early. No tenants have been signed, according to a spokesman. But we should hear some news soon.
"At this time we're extraordinarily focused on Phase 2 and we'll be ready to talk more about Phase 3 in the coming weeks," said Flats East director of marketing Heidi Yanok.
See the map below for where Phase 3 would fit into the plans. (The red box in the middle.)
