Project Description

ADD Inc, now with Stantec, completed the design of One Channel Center, the final phase of the seven-acre Channel Center master plan, a 2.1-million-square-foot mixed-use development by Commonwealth Ventures.

The $175 million project is located at 1 Iron Street in the burgeoning area of the Fort Point Channel in Boston’s Innovation District, the largest urban redevelopment near a major downtown area in the country. The 500,000 square foot, eleven-story structure is home to approximately 4000 employees of State Street Bank and is part of a multi-building masterplan that includes a new two-acre park and a ten-level, 900-car garage.

The design team’s vision for the project was based on a digital vortex, a concept that aligns with the technology-focused culture of State Street Bank, the building’s only tenant.

“We are extremely honored to be part of such a landmark development as Channel Center and to have our architectural vision for the One Channel Center building represent the conclusion of this momentous project,” stated architect B.K. Boley, AIA, Principal, ADD Inc, now with Stantec.


In order to reduce the apparent scale of the building, the design team divided it into three parts. Two volumes flank a a sloping glass curtain wall entry façade at the building’s center. The curtain wall is a design gesture that breaks down the visual scale of the building, delineates its entry, and it transforms to a shimmering light display at night.

The two masonry sides of the building incorporate textured red and brown precast concrete, which resembles brick and terracotta in a nod to neighboring historic warehouses. Colored glass panels punctuate the façade and evoke the whirling activity of the office within.


Designed to thread into the neighborhood context, the two-story lobby is a portal between the historic warehouses on Channel Center Street and the new park on the building’s southern edge and features local art.


One Channel Center features many green elements, such as continuous insulation on facades, efficient mechanical systems (HVAC), recycled and local materials, such as structural steel and precast concrete, and low VOC materials that improve indoor air quality. The building is expected to attain LEED Silver Certification.
