Proposed replacement of five windows on the fifth story of the Southeastern Glass Building.

The existing windows are the original multilight steel windows, featuring twenty lights total, with operable four-light awning windows on the center of the window. All exterior trim and sills will be retained. The proposed replacement windows are single-light aluminum storefront windows with surface-applied muntins and rails, to be applied on the interior and exterior. The topmost muntins and rails will measure .75", to reflect the existing. A six-light casement window will be located on the lower half of the window, surrounded by muntins and rails that measure 3.5" wide.

Full replacement windows were approved by the DRB in March 2024 (2-B-24-DT), with final specifications submitted to staff in July 2024 (included in packet, Advanced Glass Cooperative, Inc. specification). The intent was to issue a blanket approval of one specific type of window, approving a specification which all replaced windows shall be match moving forward. The proposed windows differ from the previous approval primarily in operation and design, featuring a six-light casement window instead of an awning window. The current application notes the slightly larger size of the fifth story windows.

Guidelines recommend that if repairs are not possible, replace with matching windows, including duplicating design, operation, material, glass size, muntin arrangements, profiles, and trim. The proposed replacement windows will vary in design; material (using a surface-applied grid, of aluminum instead of the original steel); and profiles (surface-applied exterior muntins are typically more thin than steel muntins).

For the previous application, the contractor submitted a detail of the existing steel muntins, which are flat and measure approximately .75-inch, and a profile of the proposed, which are flat and measure .75-inch. The proposed windows for the fifth floor reflect these measurements, other than the section surrounding the casement window. Overall, the variation in operation is not significantly different from the existing windows or the proposed specification featuring the awning windows. From the street level, the windows will be visually similar. The applicant is in conversation with the HOA regarding using the casement product instead of the awning window approved in March 2024.
