Owners of 15 Bank Street presented a preservation‑oriented packet to the committee proposing new ironwork at the façade to match neighboring 13 Bank Street, a painted wood pergola at the roof to match an existing pergola on the sister house, and modest changes to rear windows and paint on a reconstructed rear elevation.

"The proposed window guards, area way and stoop ironwork are proposed to match 13 Bank and other historic examples on the block," Sarah Bridal of Higgins Quaisbarth and Partners said. She told the committee the new parlor‑level guards and stoop railings respond to Italianate detailing visible on nearby houses and to an earlier photograph that depicted balconettes on the row.

The rear façade changes would increase several fourth‑floor window heights by approximately seven brick courses to match 13 Bank. Applicants said the rear wall at 15 Bank was reconstructed in 2008 and is not historic fabric; because it is not visible from public ways the team proposed painting the back façade white to better relate to the sister property.

A small pergola about 9.5 by 14.5 feet and set back from the parapet by roughly 6 feet is proposed on the roof to match the existing pergola at 13 Bank; visibility studies shown by the applicants indicated minimal public visibility from across the street and along Waverly Place. Committee members discussed maintaining distinct house identities despite the matching ironwork and asked the applicants to preserve the individual stoop entries and cornice breaks that separate 13 and 15 Bank.

The committee raised no major objections and asked for details to ensure the proposed ironwork would be in the round (visible from both faces) and for samples of finishes; applicants said the proposed work largely aligns with approvals already issued to 13 Bank and with other historic railings in the row.
