A developer has updated plans for a 389-room hotel in Boston’s Kenmore Square.

The new designs call for a 28-story, 221,000-square-foot tower and reconfiguration of the five-way intersection creating a rotary-like traffic pattern.

A previous proposal called for 382 hotel rooms in a 161,000-square-foot tower rising 24 stories.

The new flatiron-style footprint of the hotel tower on the existing Citizens Bank branch parcel would leave space for a public plaza, Wellesley-based Mark Development said.

The design would improve walkability and bicycle routes in Kenmore Square, where pedestrians have to wait up to two minutes for a walk signal before crossing seven lanes of traffic, according to developers. A new cut-through street would enable eastbound Commonwealth Avenue traffic to turn right onto Beacon Street before the existing intersection. Westbound traffic on Beacon Street would continue past the existing intersection, before turning left onto Comm Ave behind the new hotel, creating a rotary-like traffic pattern.

The original proposal included a 19-story hotel on Beacon Street to the rear of the Buckminster Hotel. That parcel is not part of the updated plan but will move forward under a separate permitting process led by Buckminster Annex Corp., Mark Development said.
