A pair of proposed hotels totaling 677 rooms in Boston’s Kenmore Square are generating pushback from residents who say the project shouldn’t qualify for special zoning rules allowing extra density.

Wellesley-based Mark Development and Buckminster Annex Corp. submitted plans to the Boston Planning and Development Agency in May 2017 to redevelop parcels at 560-574 Commonwealth Ave. and 651 and 655-665 Beacon St. into a pair of 24- and 19-story hotel buildings totaling 347,000 square feet.

The debate centers on whether the Crossroads at Kenmore project qualifies for a planned development area review, which allows developments to override existing zoning on sites that are larger than 1 acre.

The hotel proposal incorporates the nearly 1-acre Buckminster Hotel property on Beacon Street along with Mark Development’s 6,030-square-foot Commonwealth Avenue parcel, which is occupied by a single-story bank branch.

An attorney for residents of the 111-unit Kenmore Tower housing cooperative, which borders the bank site, argues that the project doesn’t qualify for a planned development area review. The project site incorporates the existing Buckminster Hotel but no development is planned except on separate parcels containing a parking garage at 651 Beacon St. and a small office building at 655-665 Beacon St.

“Almost 40 percent of the total land area necessary to qualify the site as over an acre is not actually part of the proposed development,” attorney Ann Sobolewski of Posternak Blankstein & Lund LLP wrote in a comment letter to BPDA.

Fenway Community Development Corp. submitted a letter of opposition, noting that the 24-story Commonwealth Avenue hotel would be built 17 feet from some Kenmore Tower residents’ balconies.

“This will decrease their quality of life and residency significantly,” wrote Richard Giordano, director of policy and community planning for Fenway CDC. “They will have a bird’s eye view of their neighbors in their hotel rooms instead of downtown Boston.”

The Boston Preservation Alliance requested additional renderings from the developers to gauge the Crossroads’ effect on Kenmore Square, where developer Related Beal this week submitted plans to redevelop a 1.1-acre site with 253,000 square feet of class A office space and retail.

“For everything the neighborhood gains with the continuing wave of new development, it loses in grit, authenticity and history,” Executive Director Gregory Galer wrote.
