The core of the KHM26 house was built from concrete and wrapped in a a steel shell welded into a single piece. The architects predicted the use of highly precise building techniques that would allow for the construction of a water-tight shell. Its lowest storey is set below ground level in order to function as a foundation and houses three rooms that can be used as bedrooms.
Most of the ground floor accommodates an open-plan living room, dining room and kitchen, while the first floor, with its glazing, provides views of the surrounding landscape and boasts a large protected terrace. The top floor, tucked under a slanted roof, has large master bedroom with a roof terrace.
By using a less conventional building technique, the architects were able to build the house with a high level of precision without having to resort of lightweight building materials. The transportation process took two days and included the use of the largest cranes in the Netherlands with a 260-ton capacity that ensure the massive home was lifted safely.
