Beth Israel Deaconess Medical Center plans to construct a new 10-story patient care building, its largest such project in more than 20 years.
The building in Boston’s Longwood Medical Area would house private patient rooms, operating rooms, and imaging facilities, and it would include a rooftop landing pad for medical helicopters, according to a letter hospital officials filed with the Boston Planning & Development Agency.
The building would have 345,000 square feet of space and would be located on the western end of the hospital campus, at Brookline Avenue and Francis Street, according to the submission, which the city agency released Monday.
Hospital officials said they are in the early stages of planning and expect to file more detailed plans next month. They did not say how much the project would cost or when the new building would open.
“After detailed assessments of our existing space and the evolving clinical needs of our patients, we are proposing a new inpatient building on our West Campus,” Jennifer Kritz, a spokeswoman for Beth Israel Deaconess, said in an e-mail.
“Our focus is on ensuring our patients and their families have access to modern rooms that promote healing and can accommodate the sophisticated technology and team-based care needed to best treat our increasingly high-acuity patients,” she said.
Beth Israel Deaconess has 671 patient beds and is among the largest teaching hospitals in Boston.
The filing Monday kicks off review by the Boston Planning & Development Agency. When more detailed plans are submitted, the agency will form a neighborhood review committee and hold public meetings before a board vote on the project.
In addition, the project will need approval from the state Department of Public Health, which considers factors such as patient needs and the project’s costs.
Beth Israel Deaconess is also seeking approvals for a big merger with Lahey Health of Burlington, New England Baptist Hospital of Boston, Mount Auburn Hospital of Cambridge, and Anna Jaques Hospital of Newburyport.
Hospital officials said their planning for the new building predated merger talks.priyanka.mccluskey@
