Rem Koolhaas's firm recently completed a space for the new Hong Kong branch of longtime New York City gallery Lehmann Maupin. Located inside the 1920s neoclassical Pedder Building, the renovation stripped the interior back to its structure but left some layers of construction from previous renovations visible on a central column and ceiling beam. The spare design by partner David Gianotten and project architect Miranda Lee relies on simple but tough materials, including wood panels for the reception area, bookshelves, and a sliding partition that separates the gallery's two exhibition areas. A glass entry wall framed in steel opens completely into the space. The gallery opened on March 14 with an exhibition of work by Korean artist Lee Bul. Click the image above to view a slide show.
