Marcus Partners will partner with minority- or women-owned architects and construction companies on a 228,000-square-foot office and lab development in South Boston’s Raymond L. Flynn Marine Park.

The Boston-based developer said it’s planning a 219,000-square-foot office-lab building on parcel O along with adaptive reuse of a 9,000-square-foot building on parcel P for amenity space for the new building’s tenants.

Reflecting the Boston Planning & Development Agency’s recent commitment to bolster minority participation on publicly-owned development parcels, the developers plan to enter a joint venture on design as well as construction, and offer to provide an equity stake in the project to underrepresented investors of color and women, according to a notification form by Marcus Partners Principals Levi Reilly and Patrick Sousa.

The two parcels are owned by the BPDA’s sibling agency, the Economic Development Industrial Corp. of Boston. Marcus Partners recently acquired the property from Au Bon Pain for $25 million and renegotiated the ground lease with the EDIC to reflect an anticipated larger income stream from the new uses. The new 70-year ground lease calls for payments of $2.2 million beginning in 2024, according to a BPDA memo.

Parcel O, located at 19 Fid Kennedy Ave., spans 1.6 acres and has been home to the Au Bon Pain headquarters and bakery since 1982. Parcel P covers nearly 0.6 acres at 3 Anchor Way and contains a 12,324-square-foot manufacturing building.

Au Bon Pain did not return messages about its plans to replace the facility.

Availability of large industrial parcels in the Seaport District and marine park for higher-renting uses such as office and lab space has prompted a series of transactions by developers in recent weeks. Alexandria Real Estate Equities paid $168.5 million for a pair of industrial properties on E Street spanning six acres in November, and The Davis Cos. is proposing a 331,000-square-foot addition to the 88 Black Falcon complex.

And Milllennium Partners received approval this month for a 380,000-square-foot office-lab complex on the EDIC parcels T and T1, spanning 4.4 acres at 2 Harbor St.

The Massachusetts Executive Office of Environmental Affairs is reviewing a proposed new master plan for the marine park that would allow developers to build non-marine dependent uses such as offices and labs on upper floors of buildings. The agency sought additional information from the BPDA in February.
