115 S Jackson is a comprehensive renovation and adaptive reuse project that transforms a former plumbing warehouse into a vibrant mixed-use building housing 26 lofted micro-units. Originally built as two separate buildings (115 & 119) before being joined together in 1929 with one of the neighborhood’s only Art Deco facades, the project required significant modification to provide much-needed residential units to the district.
The previous union of buildings resulted in an inconsistent second-floor level where the lofted units were planned to be placed. The solution was an “over framed” new floor on the 115 side to provide a consistent level across both buildings. The floor was used to tie the two buildings together structurally by connecting to new seismic frames on the 119 side. Once this was done, windows were introduced to make the units viable.
The unique micro-units consist of identical compact entry/kitchen/bath/loft cores, featuring effective programmatic stacking designed for functionality and comfortable living. Exposed brick frames the units’ alley-facing windows, a contrast to the prefabricated steel detailing inside.
An added penthouse contains another ten apartments and a large rooftop amenity deck with views of the water. Neighborhood preservation guidelines limited the addition to a single-story but the design team was able to creatively squeeze 12’ ceiling heights into all of the units. The design feature makes the small footprints, some as small as 250 square feet, feel generous and spacious.
The micro-units are accessed from the alley, drawing occupants in to further activate the space. Parking is not included in the design; instead, a bike club, bike storage, and locker room are offered in support of a healthier commute. To make alley-facing retail possible on the ground level, the structure was modified to “step” with the grade, allowing for a variety of retail configurations over time. New entries were created by re-opening infilled windows or by extending existing openings all the way to the alley level.
