Historic Zoning Commission

Concord Village HZ: Level III

2-F-18-HZ

Staff Recommendation

Staff recommends approval with the following conditions:
1) that the garage door openings be two separate ones as shown in the drawings and overhead doors to appear as side-opening carriage house doors. Confirmation of service door type (shown as single-light or single wood panel door on submitted drawings) with specifications for both to be provided to staff for approval.

2) that a sample of brick for foundation and chimney (if constructed) be provided to staff for approval. Staff recommends pricing a masonry chimney stack for the wood stove vent, but the chimney stack is not required as a condition of approval.

3) The garage peak should be made to be more significantly lower than 1 foot than that of the house since no precedent has been discovered by staff or provided by the applicant for accessory structures that are nearly the same height as the main house.

Other staff recommendations for the record:
1) Staff has recommended that the applicant consider constructing two separate accessory structures on the site, one for the garage and one for the workhshop, since more than one accessory structure is not atypical for the district. Accessory structures that have a width and height that are the same as that of the main structure and have more square footage than the main structure, such as the proposed, are not typical in the district.

2) A second option recommended by staff was to attach the garage to the rear or side of the house to provide more mass to the primary structure on the lot, while reducing the mass of the accessory structure. However, the applicant chose not to pursue either of these options.

PRECEDENT: Approval of the proposal as submitted will set a precedent for allowing an accessory structure to have more square footage than the main house and to have greater width as viewed from the street. However, the massing can be required to be broken up under different roof structures, and the roof peak of the garage be at least 1 foot lower than that of the main house as in the current proposal. Additionally, any accessory structure larger than the main house can be required to be at least 36 feet to the rear of the main house as in the current proposal.

Level III. Construction of new primary building
Other: new house and garage construction
HOUSE: Proposed primary residence for 10817 Second Drive is a 24'w x 50'h one-story wood-framed front gabled rectangular form with a 9'-0" ceiling height and an unfinished attic with a floor-to-roof-peak height of 21'-6'. The house floor will sit at approximately contour 824' so that the front porch will be at ~3'-6' above the finished grade in front and approximately 1'-6" at the rear. The foundation will be of Meridian Brick -Olde Fort Augusta of the Augusta Collection. The brick cap will be 5" sloping 2x treated and painted lumber.

The house will be fronted by a 8' x 16' porch with a 5-V metal-clad hipped roof at a 3/12 slope. A shed-roofed clerestory dormer with a pitch of 3/12 projects from each side of the upper roof. The dormer ends will be clad in straight-edged fiber cement shakes. The house will be clad in fiber cement board 6" horizontal siding with smooth finish out. The 8'-deep front porch features a 3/12 hipped 5-V-groove metal roof supported by 9x9 built-up wood posts (with base trim) and a 2x2 square wooden balustrade at 36"-high. Porch posts may be chamfered, eliminating the base trim. Both front and back porch will be wood-framed with tongue-and-groove wood flooring. Solid wood front and back doors will have a .5 -light above and a wood panel below, and will be topped by a 1'-0"h transom. Windows will be aluminum-clad one-over-one.

GARAGE: The proposed detached 24'x35' frame front-gabled garage is one-story with an unfinished floor above. The garage is 22'-6" from slab to peak. The garage will be concrete slab on-grade, however, it is set into the natural slope with the floor at (approximately) elevation 822.5 contour so that a brick-covered retaining wall will wrap around the front approximately 1'-6" above the slab. Height range for the garage foundation is 1'-6" at the front to 3'-6" at back. The rear retaining wall may end up being higher once grading is established.

The garage will have two 10'w x 25'l shed structures, one attached to each of the east and west sides with a 3/12 5-V, 26-guage galvalume metal roof. The main garage will be clad with 6" fiber cement board horizontal siding, smooth-side-out. The walls of the west shed (facing Olive Drive) will be clad in vertical fiber cement board-and-batten siding and have a service door. The shed facing the adjacent east neighbor will be unenclosed and supported by 9x9 wood square wooden posts at the outer corners. The garage will sit approximately 36' from the rear of the house. The overhead garage door and pedestrian garage door specification will need to be provided and approved by HZC staff.

Staff Comments
vacant lot: ~ 120 w x 160 d at 19,195 square feet in area
    Former c. 1887 house which was demolished in 2017 was a vernacular one-story frame dwelling with aluminum siding. Heavily altered from front-gable-and- wing configuration, as well as deteriorated structure; therefore, considered to be non-contributing.

INFILL AND NEW CONSTRUCTION
New buildings should be compatible with surrounding architecture, but their design should recognize that they will function as a new building and will be built with new materials. . . .New buildings constructed in historic areas should, however, be compatible with older structures and sensitive to the patterns already in that environment. A building should not be visually incompatible or disrespect historic relationships within the neighborhood.

WIDTH OF HOUSES AND LOTS
. . .The form of the houses is rectangular or irregular, with narrow sides facing the street. This development pattern should be respected if new structures are built in the neighborhood

SCALE AND MASSING
. . . The size and proportions of new buildings should be consistent with historic or adjacent buildings in the neighborhood. Recessed or projecting porches, bays and other details should be incorporated into any new construction. Any new buildings should complement and reinforce neighboring buildings. . . .

OUTBUILDINGS
Auxiliary or outbuildings are sometimes found in Concord, and would have included carriage houses, barns, outhouses and sheds. . . . Buildings that resemble carriage houses, work buildings or simple one-story garages may be appropriate for the historic district. Their size and construction should duplicate the original outbuildings that would have been found.

RESIDENTIAL BUILDINGS - RECOMMENDATIONS:
1. Maintain the facade lines of streetscapes. Never violate the existing setback pattern by placing new buildings in front of or behind the historic setback line, or at odd angles.
2. Relate the size and proportions of new structures to the scale of adjacent buildings.
3. Break up box-like forms into smaller masses like historic buildings. New buildings should be designed with a mix of door and window elements in the facade mimicking nearby historic houses.The placement of door and window openings should be imitated.
4. Relate the vertical, horizontal character of new buildings to the directional alignment of nearby buildings.
5. Relate the roof forms of the new buildings to those found in the area, duplicating existing roof shapes and pitches.
6. New buildings shall equal the average height of existing adjacent buildings.
7. New housing shall be built with raised foundations or designed to suggest that there is a raised foundation equal to the foundation height of adjacent buildings.
8. In new buildings, the height of roofs and eaves, stories, windows and doors shall mimic adjacent historic buildings.
9. The materials used for new buildings shall be consistent with existing historic building materials along the street.
10. Front elevations shall have a strong sense of entry.
15. Garages and other outbuildings shall resemble outbuildings that have been historically constructed in the Village of Concord.
