The plant will incinerate waste, from nine surrounding municipalities and from many places abroad to produce electricity and heat power for the whole region of Roskilde. To provide the huge new incinerator line, planned in a relatively flat landscape and next to the relatively small city of Roskilde with a suitable appearance, an international design competition was organized. In 2008 the jury unanimously selected the design proposed by Erick van Egeraat. The design presents an iconic expression for the otherwise functional architecture of the local waste management company Kara/Noveren’s next generation incineration line. The façade consists of two layers: the inner layer is the skin which provides the actual climatic barrier, allowing the second skin to be treated more freely – raw umber-coloured aluminium plates with an irregular pattern of laser cut circular holes. The aluminium plates are treated to give them the desired colour and patina at day time. At night, the programmable lighting, installed between the two facades, gives the building an additional metaphor.
The house is centrally positioned on the building plot at the edge of a residential neighbourhood and opposite a small forest. An explicit orientation to the sun shapes the tripartite composition of the house. Three gardens formally complement the composition, each garden intended for a specific time of day: morning, afternoon, evening.
A symmetric spatial configuration of three cubes around an equilateral triangle, together with an asymmetric articulation at the carport, defines the building geometry. The volume is developed architectonically through a concrete and blockwork loadbearing structure, brickwork of hand-selected peat-fired bricks in Flemish bond and hardwood carpentry with prominent arched windows on the ground floor and rectangular windows on the upper floor.
The living area with open floor plan clearly shows the building geometry. The three large arched windows on the ground floor bring daylight generously into the space and at the same time create a close relationship between the interior and the three gardens. The three blind end walls within the open space contain integrated cabinets that allow the eating area, seating area and work area to find their appropriate place. Warm, natural materials and colours enliven the living area: wooden wall paneling throughout the space, a light-pink-and-sand-coloured terrazzo floor with an integrated kitchen worktop.
