"That lease is signed," relays Robert Doherty of the Beal Cos.,the Boston-based real estate and investment firm that acquired thebuilding in May 2006 in partnership with Rockpoint Group LLC.Doherty says Ihrsa will be relocating to the property by year's endfrom 263 Summer St., also part of the Seaport District.

Previously known as the Fargo Building, 451 D St. was taken backby its lender prior to Beal and Rockpoint's acquisition. A plan toconvert the building to residential had resulted in the departureof several tenants, but upon buying the asset, Beal and Rockpointundertook a campaign to restock Seaport Center as an officebuilding. The effort has already yielded a number of sizeablecommitments, including a Hart-Hanks subsidiary, the Aberdeen Group,which leased 26,000 sf in thefirst quarter, as reported by GlobeSt.com.

Previously, the New York City-based investment group JP Morgan,was rumored to be negotiating a six-figure lease at Seaport Center.Doherty continues to decline comment on that or other rumoredsuitors for the building, citing confidentiality agreements inplace. Nonetheless, sources insist JP Morgan is in talks to bringdivisions from Boston's Financial District to Seaport Center, afterthe firm had entertained a departure to the suburbs.
