Mark 50 Magazine - House on a Stream   In early February, Mark Magazine  announced an open competition for a cover design to celebrate the magazine’s 50th issue. No fewer than 540 entries from 48 countries made it anything but easy to single out the best proposal. This issue takes a walk through Steven Holl’s striking addition to the now tragically damaged Glasgow School of Art, as well as Morhosis’ Emerson College in Los Angeles, revel in Richard Weston’s crystalline fabric patterns and marvel at Leonardo Portus’ photography of imaginary architecture models. After a weekend break in an off-grid holiday house by Architecture BRIO near Mumbai and an active vacation at Álvaro Andrade’s rowing centre in Portugal, we finish with a few literary recommendations by Hans van Heeswijk.
