Callahan Construction Managers

26-acre site will create over 300 apartment units across 17 buildings on former retail site

PORTSMOUTH, NH – December 4, 2025 –  Callahan Construction Managers (Callahan), a full-service construction management company headquartered in Bridgewater, Mass. with offices in White Plains, NY, announced today that it has broken ground on Prescott Post, a significant residential development located in Portsmouth and featuring 17 standalone 3-story walk-up and 4-story elevator buildings. The project’s developers are Eastern Real Estate and The Kane Company, which have collectively overseen the development and management of millions of square feet of properties across the U.S. and within New England.

The 360-unit market rate project will span a 26-acre site on what was formerly the home of a long-vacant Christmas Tree Shops and Bed, Bath, and Beyond retail stores. Featuring a mix of studios, one-bedrooms, two-bedroom and three-bedroom units, the community will boost Portsmouth’s housing stock while also preserving open space and introducing amenities that reflect the hybrid and flex-work lifestyles many young professionals have adopted.

Prescott Post will include over 2.7 acres of green space, which will be used to provide residents with access to a public dog park, multiple recreation areas with grills and picnic tables, community walking paths, and greenways. A shared indoor residential amenity suite will be centrally located within the site on levels 1 and 2 of one of the community’s 4-story buildings, and social gathering spaces abound. A clubroom, resident game lounge, private work pods, and outdoor lounge spaces are among the numerous proposed amenities. In addition, an indoor/outdoor fitness facility will offer recreational activities for all skill levels and abilities.

“Portsmouth is one of New England’s most exciting cities, and Prescott Post will create opportunities for current and future residents to experience all that it has to offer,” said Steve Callahan, Jr., Vice President – Business Development for Callahan Construction. “We are particularly excited to be part of the team responsible for bringing it to life, and to work closely with city leadership and residents to build a project all can be proud of.”

Callahan recently completed the 75 Canal residential development in Manchester, which was recognized with a Build New Hampshire award from the AGC of NH. For more information on Callahan’s residential market expertise, click here.
