A design for new infill on an architecturally distinguished and landmarked block of Hancock Street needs refinement, the city’s Landmarks Preservation Commission said at its weekly hearing on Tuesday, October 22. While the commissioners were, overall, enthusiastic about the front of the new building’s design and detailing, they agreed the rear was too massive and extended too far into the interior of the block – an area sometimes referred to as the “green donut” – compared to neighboring row houses. Members of the public who spoke also took issue with the width of the proposed building.
