Each of the historic districts neighboring the Central Area has a particular character that should be reflected in the designs for buildings on individual parcels. Throughout the Central Area, the design of all new buildings and landscape features should contribute to the quality of surrounding historic districts by their compatibility with heights, scale, materials, colors, textures, façade treatments, architectural detailing, and the relationship of buildings/features to the street. New development should reinforce the historic pattern of strong street edges, with buildings set on the sidewalk line. The continuation of active ground floor edges and pedestrian-oriented design is encouraged throughout the corridor, reflecting the first floor storefronts prevalent in adjacent historic neighborhoods.
Design principles for joint development projects adjacent to historic resources were developed prior to the parcel specific guidelines, and follow the Section 106 regulations and the Secretary of the Interior’s Standards for the Treatment of Historic Preservation Projects. These Standards encourage new design to take existing architectural themes into account, and to interpret rather than imitate historic architecture. The Standards specify that new construction should preserve the spatial relationships that characterize historic resources, and that “new work shall be differentiated from the old and shall be compatible with historic materials, features, size, scale and proportion, and massing to protect the integrity of the property and its environment.”
The Guidelines for Applying the Standards further direct that “new work should be compatible with the historic character of the district or neighborhood in terms of size, scale, design, material, color, and texture.” The Guidelines strongly recommend avoiding the duplication or imitation of historic styles or periods of architecture.
[Specific to Parcel 9]
Massing of any new development on this parcel should reflect the low buildings and irregular street pattern of the adjacent Blackstone Block. This historic district, which has been designated as a Boston Landmark, is composed of a variety of architectural styles that are related by their small scale and similar materials, and feature both pitched and flat roofs. The irregular street pattern in this district creates unusual building shapes and massing. Hanover and North streets are intended to be major pedestrian connections between the North End and Government Center, facilitated by the removal of the elevated Central Artery structure. Building facades along all four perimeter streets should reflect the historic pattern of first floor storefronts throughout this area. The design of this site should respond to the historic scale, character, and development patterns of the parcel, and to the early industrial history related to Mill Creek, which ran along the west side of the site. Recent archaeological discoveries at the site of Mill Creek provide significant new insights to the history of this area.
