Commission approves Nonantum façade tweaks, narrows roof walk and requires parapet

The Nantucket Historic District Commission voted March 10 to approve revisions to a recently altered house on Nonantum Street that included a narrower roof walk and changes to porch and deck detailing.

The applicant, Ben, told commissioners the goal was to improve symmetry on the front facade by reducing an overly deep front porch from about 12 feet to 8 feet, adjusting fenestration and adding a roof walk compatible with neighboring properties. Commissioners praised the effort to simplify massing and restore compositional balance but debated material choices and proportions.

Commissioner Ray said he viewed the changes as a “net benefit” and urged the roof walk be left to weather naturally. Commissioner Angus supported most revisions but preferred the porch proportions be carefully balanced with the second-floor balcony. Commissioner Val and others said a natural roof walk and shingled parapet would be more in keeping with the street.

Commissioner Ray then moved to approve the application with conditions requiring the roof walk be reduced by two feet in length, left to weather naturally, the second-floor deck above the front door to be a shingled parapet instead of an open railing, and that the deck align with the corner boards as shown in the submitted drawings. The motion passed by voice vote with one commissioner recorded in opposition.

The commission’s approval was accompanied by a requirement that final details be submitted as Exhibit A and that staff incorporate those conditions into the Certificate of Appropriateness.

The applicant will receive a written decision from staff specifying the as-approved exhibit and the conditions that must be met during permitting and construction.
