The current building boom on Columbia Point could include more hotel rooms if a plan by the Bayside DoubleTree Hotel on Mt. Vernon Street is approved by city planners. The DoubleTree would add a new wing to the rear of its current building under a plan filed with the Boston Redevelopment Authority (BRA) last week. The news was first reported in the Boston Business Journal.

The six-story addition would include 86 new guest rooms, a 3000 square-foot restaurant and a ballroom, according to the newspaper. The hotel presently has 197 rooms and a small, take-out café that serves coffee, sandwiches and snacks.

Bayside Club Hotel LLC wants to build a six-story addition that would allow 86 new guest rooms next to the existing hotel. The hotel has 197 guest rooms now. According to the proposal, the existing hotel would remain open through the expansion.
