The aardehuizen in Olst were inspired by Earthships of architect Michael Reynolds. The first Earthships date back to the ‘70s and have been tested thoroughly by use. Discarded materials and local building materials determine the buildings. An earthship is designed for off-grid living.
Architect Michel Post of Orio Architecten has modified the design to meet Dutch conditions. (rains, temperature through the year and soil).
12 of the buildings have tire walls - filled with rammed earth - supporting the roof. The other 11 buildings are built with straw walls with a wood frame supporting the roof. The roofs are slanted 9º to catch a maximum of sun in winter and very little sun in summer.
