Villa Criss-Cross Envelope is a minimalist house located in Ljubljana, Slovenia, designed by OFIS Architects. The Villa is located in the Mirje Suburbs within the city center of Ljubljana, Slovenia. The street of the villa runs perpendicular to the ancient Roman Wall and continues into a pedestrian passageway under the stone pyramid designed by Plecnik. The Villa’s new structure embeds an existing retaining wall along the street front. By incorporating the wall as part of the new construction, the new house keeps original position on this street in an axial alignment to the pyramid.
