Aichinger House by Hertl.Architekten was a restaurant with two bars but the challenge for the architects was to renovate one of the bars into two flats. The architects created a dynamic exterior design using light gray curtains to contrast with the concrete building. Allowing for privacy, the curtains can be pinned back just like interior curtains to allow light to come in through the windows. From afar, the exterior looks like rippling concrete flowing in the wind.
