Designed in collaboration with Sagan Piechota Architecture, this old concrete building was made modern by revealing its original structure and adding a collage of raw materials: concrete, steel, and glass to re-purpose it into a mix of retail, office and living space. A third story was added to accommodate a conference room and a pied-a-terre above the office space. The double height skylighted atrium floods the interior with natural light. Outdoor roof terraces provide sunny and green urban oases. 315 Linden is the communal home to Build Inc, Sagan Piechota Architecture, Winslow Architecture, Urban Knitting Studio, and Blue Bottle café.
