Boston — WS Development has unveiled plans for the redevelopment of The Street, a retail property in Boston’s Chestnut Hill neighborhood. The centerpiece of the project will involve the repositioning of the three-story, 90,000-square-foot building at 27 Boylston St. to house new retailers and restaurants, as well as office space and outdoor communal areas. The project team will also upgrade the existing landscaping, architecture and public spaces. WS Development is designing the project in partnership with global architecture firm Sasaki. Completion is slated for 2023.
