The expansion project—which will be done by New York-based architect Shohei Shigematsu, a partner in the Rem Koolhaas-founded firm OMA—will drastically grow the auction house’s gallery footprint. It will expand the gallery space to more than 90,000 square feet, from a current total of 67,000 square feet—a growth equivalent to more than half an acre. A total of 40 galleries of various sizes will span four transformed floors. – Artnet
