Boston’s Seaport District Installs Thermally Broken Balcony

from Matt Capone

While the development of Boston’s Seaport District has been in full swing for some time now – It recently had a milestone in building innovation.


Watermark, in Seaport Square, is the first project in Boston to break the mold by building with structural thermal breaks for concrete balcony construction. The Watermark Seaport project features a six-story building and a 17-story luxury residential tower at a total of 275,000 square-feet with 300 apartments and 25,000 square feet of retail space. The project is  utilizing Schӧck Isokorb® structural thermal break technology for a concrete cantilever balcony overlooking the pedestrian walkways.


The Schӧck Isokorb® thermal break will help to conserve energy costs, but more importantly will ensure the durability of the structure and the comfort of its occupants.

The Seaport is one of Boston’s hottest development areas, changing the South Boston waterfront located at the corner of Seaport Boulevard and Boston Wharf Road. The tower will be part of the 25-acre Seaport Square project expected to fill in many of the Innovation District’s vast surface parking lots with more pedestrian-orientated walkways. The building itself has three outdoor spaces, a ground floor garden, second-floor terrace, and a rooftop deck.

The Watermark Seaport was designed by ADD Inc, who was recently featured in The Boston Globe’s Game Changers, recognizing entrepreneurial organizations that accomplished something “remarkable or cool” in 2013. The associated article celebrates ADD Inc’s ongoing effort to make urban living spaces more affordable and efficient.

Building codes currently fall short of preventing thermal bridging, yet it is clear that the impact of these balcony locations are significant to efficient safe buildings, and upcoming code revisions will reflect this need, following in the foot steps of the European building standards.



The Watermark Seaport is targeting LEED Gold certification. Construction is expected to be completed by March 2016.
