Applicant Request
Other: New primary structureNew primary structure fronting Jefferson Avenue. House measures 29' wide by 40' long overall, including a projecting front-gable massing on the right side. The house is proposed to be set 13' from the front property line on the left side, with a 20' by 20' concrete parking pad located at the rear of the property and accessed from the alley.
The one-story house is an interpretation of a Queen Anne cottage characteristic of the block. The house will rest on a stucco-clad CMU foundation, be clad in fiber cement lap siding (smooth-finish, 4" reveal), and feature an asphalt-shingle clad roof. The roof is a 12/12 pitch hipped roof with gable-roof massings projecting to the front (north) and left (east) side. The foundation measures approximately 2' tall at the façade and will be approximately 4' tall towards the rear corners, due to the site topography. All windows are double-hung wood. The front entry is proposed as a fiberglass, three-light Craftsman style door, and the rear door is a steel half-light secondary door. On the façade, the applicant proposes historically-appropriate window trim with sills, with 1" by 4" flat trim on sides and rear. The house also features 4" cornerboards.
The façade (north) is three bays wide featuring a canted two-part window on the left side, a centrally located entry, and a 1.5-story front-gable roof projecting massing on the right side. The façade features two double-hung windows with a diamond-pattern grid on the top sash, a Craftsman-style door, and a third window on the right side. The gable field features half-round fiber cement siding, full cornice returns (3/12 pitch standing seam metal), and a fixed octagonal window (applicant proposes a diamond-pattern window as available, with a single-light fixed octagonal window if diamond pattern is not available).
The façade also features a round projecting porch, measuring approximately 17'-8" by 12'-10" overall. The round porch rests on a poured concrete foundation (1'-6" tall approximately) is supported by 8" by 8" round tapered posts (composite/fiberglass material, base and cap shown in application specs). The porch roof is a 3/12 standing-seam metal with an angled turret-shaped roof above, which connects to the primary roof structure via a projecting roof massing.
The left (east) elevation features a centrally-located projecting front-gable roof massing, with a cornice return of 3/12 standing-seam metal and a gable field clad in siding to match the main house. One one-over-one, double-hung wood window is located on the front-gable massing. The façade's canted bay wraps around the right side of the elevation, along with the round porch.
The rear (south) elevation features a one-over-one, double-hung wood window and a half-light fiberglass door accessing a 5' by 5' wood deck. Balusters will be inset into top and bottom rails on the deck.
The right (west) elevation features one one-over-one, double-hung wood window.
Staff Comments
N/A
Roofs
1. Make the shape and pitch of roofs on new construction imitate the shape and pitch on roofs on neighboring existing houses or other houses of the same architectural style.
2. The eaves on additions or new buildings shall have an overhang that mimics the original eaves. A minimum overhang of at least eight inches should be used on new buildings or additions to existing buildings.
3. Repair or replace roof details (chimneys, roof cresting, finials, attic vent windows, molding and other unique roof features). Use some of these details in designing new buildings.
4. Materials used in roofing existing buildings or new construction shall duplicate the original roofing materials as much as possible. Asphalt or fiberglass shingles can be appropriate. [...] The color of roofing materials should be a dark green, charcoal gray, black, or dark reddish brown, to simulate original roof colors.
Porches
3. New buildings constructed in Edgewood-Park City must contain front porches large enough to provide seating. The proportion of the porches to the front facades is to be consistent with the historic porches in the neighborhood. Details such as columns, posts, piers, balustrades and porch flooring and ceilings will be built with materials that are consistent in appearance with historic materials.
Wall Coverings
3. New construction shall use materials that duplicate the appearance of neighboring historic buildings, so that the new buildings blend with the fabric of the area. This includes the use of corner and trim boards and appropriate door and window trim. If artificial siding is used on new construction, it must be vented every twelve inches, and must look like 4-inch lap siding unless a different pattern is approved by the HZC.
Infill Buildings
New buildings should be contemporary in spirit. They should not be imitations of buildings of the past; rather, they should respond to the present time, the environment, and the use for which they are intended. New buildings constructed in historic areas should, however, be compatible with older structures and sensitive to the patterns in that environment. The appearance of a building is largely determined by the materials that cover its exterior surface. Similar materials convey continuity and character.
1. Maintain the historic façade lines of streetscapes by locating the front walls of new buildings in the same plane as the facades of adjacent buildings. Never violate the setback pattern by placing new buildings in front of or behind the historic setback line or at odd angles to the street.
2. Relate the size and proportions of new structures to the scale of adjacent buildings.
3. Break up boxlike forms into smaller masses like those of buildings from the historic period. New buildings should be designed with a mix of wall areas with door and window openings in the façade like those found on nearby historic houses. The placement of door and window openings should be imitated.
4. Relate the vertical, horizontal, or non-directional façade character of new buildings to the directional alignment of nearby buildings. A new building should reinforce the horizontal and vertical connection between historic houses on the street.
5. Relate the roof forms of new buildings to those found in the area, duplicating existing roof shapes and pitches.
6. New buildings should equal the average height of existing adjacent buildings.
7. New housing shall be built with raised foundations or designed to suggest there is a raised foundation equal to those of adjacent buildings.
8. In new buildings, the height of roofs and eaves shall conform to adjacent properties. Height of stories, windows and doors must mimic adjacent historic buildings.
9. The materials used for new buildings will be consistent in appearance with existing historic building materials along the street.
10. Front elevations must be designed with a strong sense of entry.
11. Do not reproduce the styles, motifs, or details of historic architecture.
