What an amazing solution! Covering the façade with an EPDM membrane like a padded jacket or a “boatiné coat”. It’s so obvious, but not common! I only remember one similar solution on the back façade of the Frei Photographic Studio in Weil am Rhein, by Herzog & de Meuron. They also used a waterproof membrane, on that occasion made of asphalt, for the cladding.
