Arrowstreet is currently working on new upgrades and an expansion at the Bayside DoubleTree Hotel in Dorchester. Arrowstreet originally designed the six-story, 197-room hotel and conference facility for the Bayside Expo Center, completing the project in 1999. The new design includes a 70,900 square foot, 6-story addition with 104 new guestrooms, a ballroom, coffee bar, fitness center, meeting rooms, business lounge, a new bar and restaurant, and a courtyard garden. The expansion will provide the hotel a greater connection to the surrounding site by increasing landscaped green-space and providing public access to the restaurant space. The project will contribute to the revitalization of the Columbia Point neighborhood by creating an access point to future commercial development spaces and connecting those spaces to transit opportunities.
