Related Beal has acquired 6.5 acres of the Gillette campus in South Boston, in the second development site megadeal in a week for the Fort Point neighborhood.

Terms of the transaction were not immediately disclosed but The Boston Globe reported a price of $218 million. Boston-based Related Beal said it will begin community outreach shortly as it prepares to submit plans to redevelop the surface parking lots off A Street.

“We believe this site offers a tremendous opportunity to create a diverse, mixed-use development close to public transit hubs, add to the environmental resiliency of Fort Point, and expand public waterfront access,” Related Beal President Kimberly Sherman Stamler said in a statement.

Related Beal is partnering with Danvers-based Kavanagh Advisory Group on another Seaport development, the ISQ Seaport lab building which is anchored by life science incubator SmartLabs.

Newton-based National Development, Charles River Realty Investors and life science REIT Alexandria Real Estate Equities last week paid $252 million for a 1-acre development site and two buildings leased to General Electric for its global headquarters on Necco Way, bordering the Gillette property.

Gillette was represented by JLL Boston.
