Guidelines are available at Project: #2018-COA-397 LPC Meeting: October 16, 2018 Address: 2847 Welton Street Staff: Brittany Bryant Historic Dist/DLM: Five Points Historic Cultural District Year structure built: C (Period of Significance: Prior to and Including 1964) Council District: #9 Albus Brooks Applicant: Arrow B Architecture Project Scope Under Review: Façade rehabilitation and restoration Materials: Foundation: Existing Storefront & Windows: Aluminum Anodized storefront system, dark bronze finish Alley façade: 2-coat stucco system Brick infill: Salvaged brick from demolition Light fixtures: gooseneck lamps and wall sconce, various finish see page 9 Staff Summary: The applicant, Arrow B Architecture, is proposing to rehabilitate a non-contributing, main street character building in the Five Points Historic Cultural District. The proposed building rehabilitation will contribute to the commercial character of the Five Points Historic Cultural District. The Five Points Historic Cultural District is designated for its historical and geographical significance. The cultural district is made up of 98 parcels and approximately 80 buildings 9 of which are contributing structures. The building at 2847 Welton Street is a Main Street Character building, a building that was built in the district s Period of Significance. These buildings are non-contributing to the district; however, they are encouraged to be retained and reused whenever possible as they add to the Main Street Character of the District. Because integrity is not a specific objective for these buildings, additional flexibility may be appropriate for modifications made to these buildings. The existing building will be divided up for 4-new tenants with new storefronts and windows for each tenant. 2 tenants (tenant 103 and 102) will be located along Welton Street, one tenant (tenant 101) will anchor the corner at Welton and 29 th Street with the final tenant (tenant 104) will be located on 29 th Street. Tenant 103 is located in the portion of the building that is recessed from the street edge. Proposed modifications to the storefront for tenant 103 include a new recessed double entry door and three operable storefront windows. A steel channel will be added to the façade spanning across the storefront to provide visual interest. The existing building façade is the simplest in terms of existing architectural ornamentation. A silver gooseneck lamp is proposed for this tenant.

2 Tenant 102 is located in the center of the building massing, on the portion of the building that has a corbel cornice design. Proposed modifications of the storefront for tenant 102 will be a new angled recessed entry storefront. The storefront will have a salvaged brick base with storefront windows with transoms above. A structural steel channel will be introduced at the top of the storefront with a structural steel column placed in the center of the recessed bay. Silver wall sconces are proposed for this tenant. Tenant 101 will anchor the corner of Welton and 29 th Street. The existing façade has a corbel cornice and evidence of infilled widows and flat arch window headers. Along Welton Street, new aluminum storefront windows with transoms will be introduced beneath the flat arch window headers, aligning with the historic sill height. The chamfered corner will have a new storefront entry with transom above. Along 29 th Street, new aluminum storefront windows with transoms will be introduced beneath the flat arch window headers, aligning with the historic sill height. The existing garage door will be infilled with salvaged brick and new storefront windows, a flat arch will be added above. Bronze wall sconces and a bronze gooseneck lamp are proposed for this tenant. Tenant 104 is located on 29 th Street at the end of the building massing with a corbel cornice. The storefront modifications for this tenant include the introduction of a new storefront door under an existing flat arch, a large plate glass window under two jack arches connected by a steel channel detail. Additional changes on 29 th Street include two new storefront windows with glass kickplate with a connected steel channel introduced towards the alley. Silver gooseneck lamps are proposed for this tenant. Along the alley façade, the building corner will be rebuilt to have brick return along the alley. The alley façade will have new aluminum storefront windows added as well as a trash/service area, screened by a new cedar fence. A glass and aluminum garage door will be added toward to 29 th Street and a steel overhead door towards the center of the alley will be added. Two new hallow core metal doors with new concrete stairs and steel tube railings will be added at the center. The alley will be illuminated with a utilitarian light fixture. Excerpted from Design Guidelines for Five Points Historic Cultural District Design Standards & Guidelines, August 2016 Standards & Guidelines 3.22 Where original features survive, consider retaining them and incorporating them into a new rehabilitation scheme. Meets Standards & Guidelines? Comments The building has been heavily modified since its construction, however, original elements will be retained. The corbeled cornice will remain intact and new openings will be introduced to coordinate with the original opening positions, the flat arches will remain intact and service as the headers for the new openings Maintain the traditional orientation of the building to the street. a. Maintain a storefront character at the street edge. b. Restore altered windows and doorways to original dimensions. c. Locate primary entrance to face Welton Street. d. On buildings with a 45-degree chamfered corner, consider locating the primary entrance at the corner. Windows and doorways will be restored to the façade, activating the street front. Openings will align with the historic flat arches. Tenant 101 will anchor the corner of Welton and 29 th Street the chamfered entrance will be reopened and service as the primary entrance for tenant 101. Storefront arrangement is typical with corner entrances, recessed angled entrances and

3 e. Maintain alignment of the storefront with others along the block Use materials that are compatible with the original materials of the building and with the setting and surrounding context. /No centered entrances proposed. The storefronts will reactive this block. Salvaged brick will be used to construct storefront bases and the corner return on the alley. The alley façade will be stuccoed over, currently this façade is CMU block. Details on the stucco finishes have not been provided, it should be a true stucco composed of sand, cement, and lime Design windows, doors, and other features to be compatible with the cultural district context. a. Incorporate windows, doors, and other openings at a ratio similar to those found on Contributing Buildings. b. Infill construction should incorporate windows and doors with similar proportions and rhythms to the surrounding context. c. When using contemporary window patterns and designs, ensure they respect the character and proportions of windows in the surrounding context. d. Maintain the typical placement of window headers and sills relative to cornices and belt courses. e. Use door widths, heights, and materials that are similar to doors in the surrounding context. f. Use simplified configurations of historic doors rather than replicating an historic door exactly. g. Use clear or near-clear low-e glass in windows. Minimal use of opaque glass is acceptable where screening is required; this does not contribute to transparency requirements. h. Exterior reflective coatings shall not be used on transparent window glazing. i. Design windows to reflect the quality and features seen in the cultural district. /No The proposed storefront system along Welton Street is a traditional storefront and window arrangement with large plate glass windows/storefronts with transoms above. The tenant 103 will have an operable storefront window, this configuration and style of operation has been previously approved by the Landmark Preservation Commission within the Five Points Historic District. The tenant at 104 on 29 th Street will have a more contemporary arrangement of storefronts with fixed storefront window with glass kickplate. The configuration of the storefront window glass and mullions is not typical of the Five Points Historic District. However, this style of storefront is often found on new construction in Denver s commercial historic districts. Staff would recommend the height of the storefront be brought up to the flat arch. Finally, a steel header is located above these storefront windows and spans across the bays. Window headers don t typically span across bays Openings should be designed to provide a depth of detail and reflect typical patterns found within the cultural district and surrounding context. a. Storefront systems and doors should be recessed into the facade. /No Storefront entrance and windows are recessed into the façade. The alley façade will be stuccoed over, currently this façade is CMU block. Details on

4 4.47 EIFS and other synthetic stuccos materials shall not be used. the stucco finishes have not been provided, it should be a true stucco composed of sand, cement, and lime Coordinate lighting with the streetscape and architectural design of the building. a. Coordinate light fixtures to be compatible with the design of the building materials. b. Use high-quality and durable materials. c. Integrate lighting into recessed entries, canopies, alcoves, and other architectural features. d. Orient lighting toward the ground floors on numbered streets to avoid negatively impacting the surrounding residential neighborhood context. Proposed light fixtures are typical of the light fixture character found within the Five Points Historic Cultural District. Lighting will be oriented towards the sidewalk. Staff would recommend that an additional light fixture for tenant 103 be considered above the entrance Service areas and groundmounted mechanical equipment shall be located to minimize impacts on the streetscape and avoid disruption of the pedestrian environment. a. Locate service areas and groundmounted mechanical equipment to the side or rear of buildings. b. Where possible, place service areas and ground-mounted mechanical equipment within a building alcove, especially if it is not located to the side or rear of a building. c. Provide access to service areas from an alley, when feasible. d. Avoid locating service areas (including trash containers) and ground mounted mechanical equipment adjacent to residential properties or public sidewalk. Service areas are located in the alley and will be screened with a 6-foot tall cedar fence. Recommendation: Conditions: Basis: Approval with Conditions 1. Ensure stucco is a traditional stucco system; 2. For tenant 104, increase the storefront height to meet the flat arch above; and 3. For tenant 104, design the steel header to respect the bay configurations below. The proposed rehabilitation will reuse a Main Street Character building and reactivate this block by introducing new storefronts along Welton Street (intent statements 3g, 3h, 3i). The proposed modifications are compatible with the original character of the building and the commercial character of Five Points (3.22, 3.23, 3.24). Proposed storefronts are compatible with the surrounding context. (4.42, 4.43). Building lighting and service areas enhance the character of the district (5.48, 5.69).
