Before X Atrium became one of our favorite event spaces, this entire building was Houston's main USPS post office, a fortress-like hub for sorting the city's mail. When OMA architect Jason Long took on POST's transformation, he pictured pulling the surrounding city into the historic structure like the tines of a giant rake, each pass cutting a distinct atrium into the building. X Atrium is one of those cuts, anchored by the sculptural X-shaped stair built specifically to carry people up from street level into Skylawn, our rooftop park above. Today that same soaring space (39-ft ceilings, nearly 13,000 sq ft) hosts everything from galas and brand launches to the immersive art of Art Club. Same historic bones, brand new purpose. 🏗️✨ #POSTHouston #XAtrium #AdaptiveReuse #HoustonArchitecture #OMA
