Mayor Martin J. Walsh and Urban Edge Housing Corporation announced that construction has started on 62 new affordable rental units at the new Holtzer Park housing development in Jackson Square. The development is part of the Boston Housing Authority’s (BHA) 125 Amory Street redevelopment, a joint venture between The Community Builders (TCB), Jamaica Plain Neighborhood Development Corporation (JPNDC), and Urban Edge to renovate and preserve 199 public housing units as affordable housing, repurpose BHA administrative offices into 12 new affordable units, and build approximately 133 units of affordable housing and 214 market-rate apartments in three new buildings on adjacent BHA-owned property.
