Boston-based commercial real estate firm Farley White Interests has purchased two Watertown properties totaling 203,395 square feet.

Farley White Interests purchased converted mill buildings at 480 Pleasant St. and 5 Bridge St., which sit on 11 acres, according to a statement. The two four-story waterfront buildings were sold by Boston Scientific Corp. The sales price was not disclosed.

The 480 Pleasant St. property was last assessed for $6.9 million and sold for $5.4 million in August 1989, according to records obtained by The Warren Group, publisher of Banker & Tradesman. The 5 Bridge St. property was last assessed for $4.7 million.

"We look forward to reinvigorating this fine property and reestablishing it as a significant contributor to the economic vibrancy of the Watertown community," said Farley White Principal John Power.

Jones Lang LaSalle Managing Directors Bill Bailey and Scott Jamieson represented Boston Scientific in the transaction. Jones Lang LaSalle was also named the exclusive leasing agent.

"We are thrilled about the opportunity to work with the Farley White team on this exciting new project," said Jones Lang LaSalle Vice President Daniel Kollar. "The property’s location, campus-like setting, unique architecture and functional office, R&D and lab space provide flexibility for a wide spectrum of user types and sizes. Coupled with a strong ownership and management team, with a proven track record for creatively structuring deals to meet their tenants’ evolving occupancy needs, we feel this project is well positioned for success."
