Marcus Partners has nearly doubled its industrial real estate portfolio with the $85.25 million acquisition of four suburban Boston properties totaling nearly 900,000 square feet.

The Boston-based developer acquired warehouse and distribution facilities at 176 Grove St. in Franklin, 326 Ballardvale St. in Wilmington, 1 First Ave. in Peabody and 57 Littlefield St. in Avon.

The transactions bring Marcus Partners’ industrial portfolio to approximately 2 million square feet in eight buildings.

The investment reflects demand for last-mile distribution space near population centers.

“Greater Boston’s warehouse/distribution sector is significantly supply-constrained relative to other parts of the country and continues to demonstrate strong tenant demand,” Ryan McDonough, Marcus Partners’ Boston Regional Director, said in a statement.

Marcus Partners now owns 7.6 million square feet of commercial real estate on the East Coast.
