Construction of the fourth residential building at the 11-acre St. Gabriel’s monastery redevelopment project in Brighton will be soon underway following the approval of a building permit for the final phase of the Overlook at St. Gabriel’s. 

The permit, which puts the phase’s pricetag at $30.3 million, is for a seven-story, 140,553 square-foot building with 111 units, according to Bldup.com. 

The overall project, located at 159-201 Washington St., was approved by the Boston Planning and Development Agency in 2017. It includes four residential buildings, restoration of the historic St. Gabriel’s monastery and the adjacent church, retention of the existing Shrine of Our Lady of Fatima and the renovation of a vacant house at 201 Washington St. A three-acre Olmsted Brothers-designed landscaped buffer along Washington Street will be restored and enhanced as well.

Work on much of the development has already been completed, including apartments at the renovated monastery and the first three Overlook residential buildings, which are available for occupancy. 

Once complete, the development will include 660 residential units split between 105 condominiums and 555 apartments, plus other amenities, a fitness center, a cafe, an outdoor pool and grills, a business center, a co-working space and other common areas.
