Phase III at Rock Row will break ground in early 2027, with all buildings and infrastructure being completed in both 2027 & 2028. Individual parcels have unique timelines, given the variety of uses and size.

Phase III buildings are currently displayed in visual renderings as “white boxes,” as opposed to finished buildings complete with exteriors that will match their final construction, which is a natural step of the development journey. As each building is designed for specific uses, we’ll make updates.

A collection of industry-leading local, regional, and national brands across a variety of store types. Our leasing teams at Waterstone and Newmark are working on some exciting developments to relay soon, which we’ll announce when approved by each tenant brand.

Housing at Rock Row in phase III will feature the following break-down of residential units spread over two buildings (Brookside and Building S).

• Brookside – 12 townhome residences 
• Building S – 267 units
  • Studio – 15
  • 1 Bedroom – 133
  • 2 Bedroom – 105
  • 3 Bedroom – 14

Phase II at Rock Row was construction of Maine’s newest medical office building, Rock Row Health Campus. The $170 million Health Campus presents a modern, advanced healthcare destination where cutting-edge clinical research and comprehensive care converge with a strong emphasis on clinical excellence, patient well-being, hospitality, and overall experience. The integrated campus features two new buildings: a substantial 200,000 square foot medical building and a dedicated 20,000 square foot Radiation Therapy Center. Since opening in April of 2025, the medical facility has seen more than 150,000 visitations by patients of on-site medical practices like New England Cancer Specialists, a Dana Farber Cancer affiliate, Dempsey Center, Rayus Imaging, Saco Bay Physical Therapy and Plastic & Hand Surgical Associates.
