DESIGN NAME: House Nordlicht
PRIMARY FUNCTION: Monolithic Bungalow
INSPIRATION: How to design for a former stonemason who wants a simple building without any joints and reveals? The monolithic structure follows the formal principles of curating space and framing the surrounding landscape through solid and void. The modern interpretation of the traditional vernacular architecture of the region, a single storey volume with an extensive overhanging roof withstands the harsh climate in winter, and hot temperature in summer becomes an inhabitable seamless sculpture cast in concrete
UNIQUE PROPERTIES / PROJECT DESCRIPTION: Situated in the Bavarian-Bohemian Forest Natural Park the single storey bungalow is a massive cast in lightweight thermal concrete. 60cm thick monolithic walls and a large roof entirely crafted in concrete with cellular glass aggregates fulfils the taught Energy Saving Ordinance of Germany. The primary energy consumption of the building is only 32 kWh per m2. Pines from the nearby forest make the formwork and become eternal as an imprint on the surface of the concrete.
OPERATION / FLOW / INTERACTION: The single storey bungalow follows the natural topography lines of the site. Each space offers a carefully arranged view over the magnificent landscape of rolling hills and the nearby forest. An open space concept of living, kitchen and dining defines the southern side of the house. Bedroom, studio and study room are unfolding towards the East and the North under one enormous roof. A cubic dormer offers a family room framing the horizon behind a gentle hill towards the sunset.
PROJECT DURATION AND LOCATION: 2017-2018 in D94086 Waldkirchen, Germany

PRODUCTION / REALIZATION TECHNOLOGY: Due to the required aggregates and limited mixing facilities, the concrete has to be transported more than 60min and becomes less fluid. During the vibration process, the aggregates start to segregate, and hollow spaces and cavities might appear on the concrete wall surface or inside the reinforcement, where concrete could not reach. The exothermic concrete process in the thickness of the wall is heating the mass up to 80 degrees. As a solution during construction, it is cooled down before casting with iced water. Also, cold water pipes in the walls are cooling the walls from inside during the curing process.

RESEARCH ABSTRACT: Future generations will have to deal with millions of m3 of hazardous non-biodegradable external thermal polystyrene insulation waste. The project aims to be more responsible and to create more value in constructing and building a sustainable low energy house. Beside renewable wooden pellet heating systems, solar warm water and an internal heating and cooling circular floor systems, the envelope of the house is made of a solid cast of lightweight thermal concrete with foam glass and natural clay aggregates. The building has an A-plus low energetic performance
CHALLENGE: Due to aggregates and limited mixing facilities, the concrete travels more than 60min and becomes less fluid. During the vibration process the aggregates start to segregate, and hollow spaces and cavities appear on the concrete wall surface. The exothermic concrete process in the thickness of the wall is heating of the mass up to 80 degrees and is cooled down before casting with iced water. In addition, water pipes in the walls are cooling the walls from inside during the curing process.
