Our Response to the COVID-19 Pandemic.


Founded in 1887, North Bennet Street School had outgrown its previous location and required a larger space where all its services could be brought together under one roof. BOND was engaged to provide preconstruction and construction management services related to the restoration/renovation of two adjacent historic North End structures into NBSS’ new home. During preconstruction, BOND worked closely with the Kennedy & Violich design team to unite the two structures through the creation of a naturally-lit, multi-level link. Interior renovations, base building systems upgrades, window replacement and exterior fa├žade restoration revitalized the buildings during construction. All work was performed in accordance with the Standards for Historic Rehabilitation. NBSS’ new home has been a catalyst for a renewed sense of energy and cultural enthusiasm in the North End. The completed school offers renewed programs teaching the arts of jewelry-making, furniture-making, carpentry, locksmithing, and bookbinding to more than 160 students, as well as meeting rooms and a large gathering space for the surrounding community.
