A 327,000-square-foot addition to the 88 Black Falcon complex will market space to life science companies while preserving traditional industrial tenants such as seafood companies in the Raymond L. Flynn Marine Park.

Boston Planning & Development Agency directors approved a 4-story addition to a former U.S. Army repair facility at the eastern tip of the Seaport District. The Davis Cos. of Boston leases the property from Massport.

The project is one of the first to take advantage of new development rules allowing higher-renting uses such as offices and labs on the upper floors of the buildings in the industrial park.

Designed by architects SGA and OJB Landscape Architecture, it will include a second-floor public observatory, new access to the Boston Harborwalk and road improvements designed to improve circulation to the Cruiseport Boston terminal.

As part of the review process, architects redesigned the addition to differentiate it from the original 1918 structure. The property is a landmark for cruise ship passengers disembarking in Boston as well as flights landing at Logan International Airport, noted Drew Stangel, a director at OJB Landscape Architecture.

“We recognized the historic significance of the existing building and worked hard to make it stand out from the newer building and celebrate its industrial qualities,” Stangel told BPDA directors Thursday.

In other development items reviewed Thursday, directors approved a new office-retail building on the last vacant parcel on Newbury Street, a peak-hour dedicated bus lane in Allston-Brighton, a condo tower in the Leather District and multifamily housing projects in Allston and East Boston.

The transportation plan for Allston-Brighton creates 4 miles of separated bike lanes. Peak hour priority bus lanes also will be created from Oak Square to Union Square, connecting to an existing bus priority lane on Brighton Avenue. Future phases could include priority bus lanes extending from Union Square along Cambridge Street to the Charles River and the future location of West Station.

Developer Hudson Group received the go-ahead for a hotel-to-condos switch for a planned development in the Leather District. Developers said the COVID-related downturn in travel made financing unavailable for a previously-approved 22-story, 230-room hotel at 150 Kneeland St., and submitted plans to replace it with a 115-unit condo tower.

In Allston, JSIP Braintree St. LLC received approval for 159 housing units in a 7-story building at 35-43 Braintree St.

Another project at 120 Braintree St. by developer Felix Shneur will create 32 residential units including a rooftop garden atop a 5-story building.

And at 7-11 Curtis St. in East Boston, SAWJNG LLC will replace a commercial building with a pair of 4-story residential buildings containing 29 units.

Replacing a parking lot at 149-155 Newbury St., Chicago-based L3 Capital will develop a 5-story building containing 26,000 square feet of office space and 17,500 square feet of retail space.

This report has been updated to correct the height and address of Hudson Group’s Leather District project.
