The Project

Once the Lokstadt area was the most important production plant in Switzerland for new locomotives and trains. Between 2018 and 2025, a new urban district will be built on this area according to the requirements of the 2000-Watt-Society.    


The area consists of both, valuable monumentsprotected industrial halls and modern new buildings. The refurbishments and conversions require great respect for the existing buildings, as well as technologically innovative solutions. When it comes to new construction projects, great importance is attached to sustainable building materials. For example, most new buildings are being constructed using timber. The "Crocodile" house is the first new building on the site and comprises 254 apartments in various forms.   


The Construction

The perimeter block building with an inner courtyard of 

2000 m2 is constructed as a skeleton structure. The wooden columns become a formative part of the architecture. The visible wooden structure gives a clear structure to the living spaces and creates a natural feeling of space. In the "crocodile" only the basements and the staircases are made of reinforced concrete, the rest of the building is made of wooden elements.


The Challenges

The "crocodile" is planned continuously according to the methods of Building Information Modeling (BIM). The coordination of the interfaces and the cooperation between the different participants is a big and exciting challenge, which we are happy to face.
