The Domino Sugar Refinery is the lone remaining historic building within a 19th century industrial complex. The historic shell was once an agglomeration of three conjoined buildings, each with its own idiosyncratic floor-to-floor configuration. Rather than navigating the misaligned window heights, Practice for Architecture (PAU) designed a new building that nests inside the existing masonry structure. By pulling back from the existing walls, ideal and standardized floor heights were achieved, while creating a unique interstitial space.
