The Musée International d’horlogerie (International Watchmaking Museum) in La-Chaux-de-Fonds could well be the first European experiment in contemporary troglodyte architecture as it was defined by Pierre Zoelly and Georges-Jacques Haefeli. It’s a buried building with remarkable spatial qualities supported by an efficient structure, constructed under a park in 1974.
At the end of the 1960s, the Swiss architect Pierre Zoelly designed a house for the sculptor Peter Hächler. He built a concrete structure, the organic heart of the house, which will be the perfect interlocutor for the sculptures it houses.
The unusual challenge of this project is to associate a kindergarten on the ground floor with a public car park underground. The hybrid building was designed to efficiently combine a coherent concrete structure between both programs.
