the conceptual design of the reflecting cube adopts the characteristics of the site, with the valley side oriented to the north and a steep slope at its back.the shiny cube of expanded aluminium rests on a recessed base of natural stone. the cube’s corners have been interrupted by deep glazing: two windows allow a visual connection to the medieval castle ruin windeck. the other two offer a view into the valley and catch the light of the morning sun. light plays a major role for the whole object. the cube reflects the daylight and changes appearance. the light is refracted by the expanded metal in multiple ways - a play of light emerges. at night the object can be illuminated by leds which are attached behind the metal facade.on the base level you find the entrance, office and garage. through a sculpturally designed staircase you reach the first level where the bedrooms and bathrooms are situated. at the top level you enter the ample, open living space with a wide window front facing the terrace and the edge of the forest, with access to the famous exotenwald.
