Recommendation
Staff recommends after-the-fact approval of the projecting entry vestibule, the fire-rated covering on the front dormers, the masonry changes, and the decrease in height on the second-story outer bay windows on the facade. Staff recommends approval of the proposed fixed single-light window to be installed in the new doors.Regarding the second-story center windows: the applicant should either a) submit documentation showing the exterior windows to be installed as aligned in plane with the adjacent second-story windows or b) select double-hung windows to replace the glass block infill, revising the fenestration opening to match the original COA and the size of adjacent windows, with a revised drawing submitted to staff for approval. Staff recommends denial of the installed slider windows in the dormer and the installation of double-hung windows as proposed, with a revision drawing to be submitted to staff.
Applicant Request
Other:- After-the-fact review of exterior rehabilitation elements which do not align with Historic Zoning Commission review and issued COA (1-D-23-HZ). The application was postponed by the HZC at the October 2023 meeting so the applicant could provide specific proposed solutions.
- Changes completed during construction are described below. The applicant has provided a response document as a revised application. The primary change proposed in the packet is the installation of double-hung windows with a tint coat in front of the installed glass block windows. The applicant proposes to retain the slider windows based on a guideline that "egress windows should comply with fire and building code provisions" and proposes a single-light window to be installed in the doors.
Façade windows:- On the center bays of the second story, glass block windows were installed instead of one-over-one, double-hung windows as proposed. The glass block windows also appear to be extended in height from the drawings, with the bottoms of the windows resting on the porch roof instead of separated by sills and 1-2 courses of brick as shown.
- On the outside bays of the second story, the windows are smaller in height and width than shown in the approved drawings. The drawings show the outermost frame of the second-story windows aligning with the outermost frame of the first story windows; as built, the second-story windows are centered over the first.
- On the dormer, windows have been enclosed from the inside with black-painted, fire-resistant backing. Photos provided indicate two pairs of sliding or casement windows on the new right side dormer (left side dormer not shown); approved drawings indicated three double-hung windows.
- On the center bays of the second story, glass block windows were installed instead of one-over-one, double-hung windows as proposed. The glass block windows also appear to be extended in height from the drawings, with the bottoms of the windows resting on the porch roof instead of separated by sills and 1-2 courses of brick as shown.
- Brick masonry:
- The COA stated that brick repair and masonry repointing should meet specifications of NPS Preservation Brief 2. The brick used as infill is different in color and texture than the original.
- Front entry:
- A projecting entry vestibule was constructed, with doors recessed from the primary façade. The approved elevation drawing depicted two multi-light exterior doors flanking a wood panel, flush with the primary elevation, and centered on the façade. The doors are two six-panel metal doors separated by a brick wall.
