About One Union Square

Welcome to One Union Square, a new vision for redevelopment that will help realize Somerville’s long-term objective of strengthening Union Square as both a neighborhood and commercial center.

With a dynamic mix of retail and indoor civic space such as a branch library on the ground floor, new office, lab and R&D space on upper floors and over 13,000 SF of green and open space in a new neighborhood park, One Union Square will anchor new economic activity while also becoming an inclusive destination for the surrounding community.
