Exterior rehabilitation to two-story, shed-roof massing on the rear elevation. The existing shed-roof section included a small upper-story porch, enclosed by a vinyl-sided railing and supported by square wood posts, with a small projecting shed roof with exposed rafter tails below, and an enclosed porch section on the first story which projects out over a basement access on the primary house massing. The first story was enclosed with vinyl siding and featured four windows on the rear elevation. A fire escape extends from the first story to the ground level.

Revised drawings provided for the September meeting show the shed roof over the first story extending the full length of the rear elevation. The first story will feature two double-hung, one-over-one windows (re-used from existing). On the second story, a shed-roof porch will project over the left half of the rear elevation. Foundation, fire escape stairs, and access doors will remain.

Scope of work also includes removal of rear roof cladding, removal existing wood fascia and soffit and replacement with new wood soffits, and the installation of new fiber cement siding with a smooth-finished, 4" exposure. The applicant also proposes to reconstruct the railing on the façade second-story porch, restoring the railing to measure 36" tall.

APPROVE Certificate 6-I-24-HZ, subject to the following conditions: 1) wood lap siding to be installed instead of fiber cement lap siding; 2) a railing detail be submitted to staff for approval prior to replacement of the front elevation balustrade.

Porches
1. Repair porches on historic houses using wood floors, balustrades, porches and columns, or replace duplicating the original size and design. Reconstruction of the documented original porch is also appropriate.

Roofs
1. The shape and pitch of roofs on new construction should imitate the shape and pitch of roofs on neighboring existing houses or other houses of the same architectural style. Replacement roofs should copy the shape and pitch of original roofs, and the soffit, fascia, and trim detail between roof and wall should mimic the original.
4. Materials used in roofing existing buildings or new construction should duplicate the original roofing materials if possible. Asphalt or fiberglass shingles can be appropriate, as are slate, standing seam metal, or metal shingle roof coverings.

Windows
1. Vinyl and aluminum replacement windows should not be used.
3. If replacement windows are necessary, they should be the same overall size as the originals, with the same pane division, and the same muntin style and exterior depth, width, and profile. False muntins or grids should not be used.
