This is The Union by architect and developer Jonathan Segal Architect. The project gets its name from its prior life as the union hall for San Diego’s textile manufacturing business. When the textile union moved away, the building fell into disrepair, and rather than demolish it, Jonathan Segal decided to adaptively reuse the structure to create sustainable live/work units and his own architectural office. The Union now includes additional buildings that, in total, comprise 13 residential loft units, of which some are market-rate and some are affordable. Also, the rooftop solar panels provide ~50% of the units’ energy needs.
