Commission recommends restoration and rear addition at 224 John Street to zoning board

The Princeton Historic Preservation Commission on May 26 voted to forward a favorable recommendation to the zoning board for a restoration and rear addition at 224 John Street in the Witherspoon Jackson Historic District.

Applicants Mark and Gabriel Beaver and architect Louisa Clayton presented plans to restore the front block—removing aluminum siding and replacing vinyl windows with fiberglass-clad wood windows—rebuild the porch with wood elements, and demolish and replace a rear addition with a two‑and‑a‑half‑story addition set back from the street. Sarah Quinlan summarized staff findings: the main block retains historic form and massing; the rear addition changes will be minimally visible from John Street; and proposed materials and massing appear compatible with the district if executed per the Secretary of the Interior standards.

Commission members asked about required zoning variances (sideyard, height/setback) and the visibility of the new rear massing; neighbors spoken at the meeting supported rehabilitation of a house they said had been vacant for years. After discussion the commission approved a motion to recommend the project to the zoning board of adjustment, with the understanding that the zoning board will review variances and additional details.

The commission’s recommendation will be transmitted to the zoning board by formal chair memo and roll‑call vote. Staff noted the recommendation is not final zoning approval and that the zoning board retains ultimate jurisdiction over variances and final site plan requirements.
