The Hamburg-based manager bought 101 Seaport Boulevard from developer Skanska for its open-ended Unilmmo: Europa fund.

The 440,000 sqft asset鈥檚 main tenant is PwC, which has taken around 82% of space.

Other tenants include Skanska and Steelcase.

The investor recently bought the headquarters of shoe brand Converse at Boston鈥檚 Lovejoy Wharf and has also invested in the city鈥檚 Godfrey hotel.

Tal Peri, Union鈥檚 head of US East Coast and Latin America, said: 鈥淎fter the acquisition of the Godfrey hotel and the Converse headquarters, we are pleased to have strengthened our foothold in the important and economically very stable gateway market of Boston.鈥

Following the three recent acquisitions in Boston, Union said its 15-asset US real estate portfolio was worth $3.8bn, making the US the manager鈥檚 main foreign investment location.
