This proposal includes a renovation of the Pryor Brown Garage building and a rooftop addition. The proposal includes retail space on the Church Ave. frontage, residential in the upper floors with the residential entrance on the Market Square frontage, one story addition on the rooftop with residential units and private and common patios, and preexisting structured parking on the ground floor with vehicular entrances on both Church Ave. and Market St.

Church Avenue (north) and Market Street (west) elevations:
1) Existing unpainted brick, concrete, and stone north and west elevations of building are to be cleaned and repaired as needed (per secretary of interiors standards).
2) Existing garage doors to be replaced with new open grille metal garage doors.
3) New metal and glass canopies to be added on the north and west elevations over the retail storefronts and at the residential.
4) All existing storefront systems on the ground level are to be replaced with new aluminum clad wood frame window system to mimic historic condition.
5) All existing exterior glazing on the 2nd thru 4th levels to be replaced with new aluminum clad wood frame window system to mimic historic windows (including operable sections as indicated on the elevations).
6) The 5 proposed doorways along Market Street will swing into the retail space and the 1 doorway along Market Street is proposed to swing out over the sidewalk.

South and East elevations:
1) Existing painted brick, concrete, and stone north and west elevations of building are to be cleaned, repaired and repainted (per secretary of interiors standards).
2) New windows opening constructed on the south and east elevations of the building and existing windows being enlarged will mimic historic window design.
3) Balconies with new door and window opening are to be constructed on the south and east elevations of the building at the 2nd, 3rd and 4th levels. Design is to be keeping with historic conditions.
4) Canopies will be installed above the 4th level balcony doors.
5) Louvers for garage venting to be installed on east elevation.

Rooftop addition:
1) The one story addition, mechanical screen and elevator penthouse will have corrugated metal siding.
2) Windows and doors will same as those on the lower level, aluminum clad wood frame window system.
3) There will be aluminum framed glazing privacy walls between the private patios. The wall will extend from the one story addition to the parapet wall and will be angled with a height no more than the parapet wall at the parapet to minimize visibility from the street.
4) The addition will be recessed from the back edge of the parapet wall approximately 12 feet from the Church Avenue elevation, 14 feet from the Market Street and east elevations, and 48 feet from the south elevation.
5) The roof will be flat and will have an overhang of approx. 5 feet over the patios.

Lighting:
1) New exterior light fixtures at the ground level to mimic historic fixtures.

Signs:
1) Remove existing signs and sign frames.
2) Conceptual locations for signs are shown suspended from the edge of the canopies and window signs at the residential entrance only. Approval of signage is not part of this proposal.

The Pryor Brown Garage is not within a National Register Historic District but it has been determined to be eligible to be a contributing structure within an adjacent national register district. The developer does intend to seek historic tax credits for the project so the renovations should match the intent of the Historic Resources section of the design guidelines even though it is not required to be reviewed under that section.

The door for the residential entrance along Market Street is proposed to swing out over the sidewalk which will require approval from the City. The proposed doorway closely matches the historic design but unknown by staff if the historic door swing into the building or out. The Market Street sidewalk is a heavily used pedestrian path and the sidewalk in front of this door is constrained because of the street tree, reducing the clear path for pedestrians building. This outward swinging door could be a hazard to pedestrians and an alternative design may be warranted even if the doorway deviates from the historic design.

Applicable guidelines:

Section 1.A.1. (PEDESTRIAN AND BICYCLIST SAFETY)
Consider pedestrians first, then transit, then the automobile in designing and developing downtown places.
1d. Widen sidewalks to accommodate street trees and amenities with a minimum 5-foot clear pedestrian passage.

Section 1.A.3. (PARKING FACILITIES)
It is important to ensure that parking facilities (both public and private) are safe, accessible, and clearly marked. New parking facilities should be designed to be attractive, compatible additions to downtown. In general, new parking facilities should remain subordinate to the street scene.
GUIDELINES:
3a. Create parking garages that do not contain blank walls. Allow for future commercial uses that may not be feasible at the time of construction.
3b. Locate parking garages under structures, or provide for retail, residential or office uses that line the garage. Corner locations are preferable for commercial uses.

Section 1.B.1 (BUILDING MASS, SCALE AND FORM)
Building form should be consistent with the character of downtown as an urban setting and should reinforce the pedestrian activity at the street level. Creating pedestrian-scale buildings, especially at street level, can reduce the perceived mass of buildings. Historically, building technology limited height and subsequently created pedestrian-scaled buildings typically less than 10 stories. Building technology no longer limits the height of buildings and there are no height limitations imposed by the zoning ordinance for downtown Knoxville. However, there is still a need for buildings that respond to pedestrians. The use of 'human-scale' design elements is necessary to accomplish this. Human-scale design elements are details and shapes that are sized to be proportional to the human body, such as, upper story setbacks, covered entries, and window size and placement.
GUIDELINES:
1a. Maintain a pedestrian-scaled environment from block to block.
1b. Foster air circulation and sunlight penetration around new buildings. Buildings may be designed with open space, as allowed under existing C-2 zoning; or buildings may be 'stepped back' on upper floors with lower floors meeting the sidewalk edge (see Area Regulations of the C-2 Zoning District).
1c. Use building materials, cornice lines, signs, and awnings of a human scale in order to reduce the mass of buildings as experienced at the street level.
1d. Divide larger buildings into 'modules' that are similar in scale to traditional downtown buildings. Buildings should be designed with a recognizable base, middle, and top on all exposed elevations.
1e. Avoid blank walls along street-facing elevations.

Section 1.B.3. (BUILDING MATERIALS)
New building materials should relate to the scale, durability, color, and texture of the predominate building materials in the area.
GUIDELINES:
3a. Use complimentary materials and elements, especially next to historic buildings.
3b. Rehabilitate historic structures in accordance with the Secretary of Interior's Standards (see Appendix A).

Section 1.B.4. (ARCHITECTURAL CHARACTER)
Buildings should be visually interesting to invite exploration by pedestrians. A building should express human scale through materials and forms that were seen traditionally. This is important because buildings are experienced at close proximity by the pedestrian.
GUIDELINES:
4a. Encourage first floor uses that draw walk-in traffic; businesses that do not require pedestrian traffic should be located on other floors.
4b. Enhance pedestrian interest in commercial and office buildings by creating a largely transparent and consistent rhythm of entrances and windows.
4c. Scale first floor signs to pedestrians.
4d. Differentiate the architectural features of ground floors from upper floors with traditional considerations such as show-windows, transoms, friezes, and sign boards.
4e. Design top floors to enhance the skyline of the block through cornices and details that are harmonious with adjacent architecture.
4f. Encourage the use of 'green roofs' and other sustainable practices, while minimizing the visual impact from the street.

Section 1.B.5. (GROUND FLOOR DOORS AND WINDOWS)
Entrances and ground floor windows should foster pedestrian comfort, safety and orientation. Not every building in downtown needs to have the same window or entry designs; however, repeating the pattern of historic openings helps to reinforce the character of downtown, differentiating it from suburban areas.
GUIDELINES:
5a. Use consistent rhythm of openings, windows, doorways, and entries.
5b. Orient primary front entrances to the main street; secondary entrances should be clearly defined and oriented to streets or alleys, as appropriate.
5c. Design entrances according to the proportions of the building's height and width.
5d. Consider corner entrances at the ends of blocks.
5e. All windows at the pedestrian level should be clear.
5f. Recess ground floor window frames and doors from the exterior building face to provide depth to the facade.

Section 1.B.7. (MECHANICAL EQUIPMENT AND SERVICE UTILITIES)
Utilities can include telephone and electrical lines, ventilation systems, gas meters, air conditioners, fire protection, telecommunication and alarm systems. Adequate space for these utilities should be planned in a project from the outset and they should be designed such that their visual and noise impacts are minimized.
GUIDELINES:
7a. Minimize the visual impact of mechanical equipment through screens or recessed/low-profile equipment.
7b. Do not locate units on a primary facade.
7c. Screen rooftop vents, heating/cooling units and related utilities with parapet walls or other screens.
Consider sound-buffering of the units as part of the design.

Section 1.C.1. (ROOFLINES AND ADDITIONS)
Alterations of the rooflines of historic buildings are not appropriate. A one-story rooftop addition, including railings, may be possible on taller buildings if it is inconspicuous from the public right-of-way. Additions should be set back from the primary elevation of the building, and should not damage character-defining features, including parapets and side walls. These walls are often topped by coping stones offering contrasting color or texture, or contain cornices, decorative grills, chimneys, corbelled brickwork and other architectural elements. Rooftop additions are almost never appropriate on buildings less than four stories in height.
GUIDELINES:
1a. Preserve or restore historic roofline features, including parapet walls and cornices.
1b. Design rooftop additions to be complementary to the historic building in terms of materials and color.
1c. Avoid construction that maintains only the historic facade.
1d. Do not alter, obscure or destroy significant features of historic resources when constructing additions.
1e. Design rooftop additions so that they are not seen from adjoining streets and sidewalks.

Section 1.C.3. (ENTRANCES)
Formal entrances to front facades should be retained. This includes entrances that are located above street level and accessed by exterior stairs. Altering or removing the main entrance to grant street-level access is not appropriate.
GUIDELINES:
3a. Establish recessed entries, either rectangular or with slightly canted sides, which are appropriate in storefronts.
3b. Allow for multiple entries on the first floor of the building, giving access to commercial space that may be divided into bays.
3c. Provide access to upper stories through additional entries.
3d. Maintain original height and materials for doors that are consistent with the use of the building, such as residential, commercial, or banking purposes.

Section 1.C.4. (WINDOWS)
Appropriate window appearance is significant in finishing a rehabilitation project. From a preservation standpoint, the first and best answer when determining a treatment for windows is to repair rather than replace them. If that is not possible, replacing only deteriorated portions is the next best alternative to total replacement. It is possible to replace window sills, rebuild all or parts of window sashes, and replace window glass, making original windows energy efficient and functional.
GUIDELINES:
4a. Repair rather than replace historic windows.
4b. Replace windows if repairs are not possible with matching windows, including duplicating design, operation, material, glass size, muntin arrangements, profiles, and trim.
4c. Insert windows with the same pane configuration, materials and size as other buildings of the same general construction date, if no original windows are present.
4d. Maintain the relationship of solids to voids with new construction that is similar to other buildings in the district, including the typical width, height, spacing, and horizontal alignment of windows.

Section 1.C.5. (MASONRY)
Masonry features should be retained and repaired; materials, including mortar, should match the original mortar in color and composition. Mortar joints should be sized and struck to match the original. Belt courses, string courses, dripstones, quoins and contrasting brick and stone are common. These features should be preserved and repaired if necessary, and should be introduced on infill buildings.
GUIDELINES:
5a. Repair masonry with stone or brick and mortar that match the original.
5b. Do not paint masonry that has never been painted.

Section 1.C.8. (AWNINGS)
Awnings are allowed on historic buildings when they are appropriate to the building and are designed with traditional shapes, forms, and materials. If awnings are used, their overall size, shape, and projection from the building must be in proper proportion and scale to the building and contained within the window or door they shelter, and not cover adjacent wall surfaces. Canvas is usually the appropriate material for awnings.
GUIDELINES:
8a. Allow awnings in traditional shapes and materials.
8b. Contain signs or advertising only within the valance of the awning.

C. HISTORIC RESOURCES
Section 1.C.9. (LIGHTING)
Storefront windows may be lit with interior fixtures, entrances may be lit with overhead fixtures, and gooseneck fixtures can be used to highlight signs. Illumination may also be used to wash the building in light, emphasizing its distinctive architectural finishes.
GUIDELINE:
9a. Use indirect lighting of the building facade where appropriate.
