The trailer was built for the needs of construction companies using it for field work. The basis of this project was an insulated bodywork of a single-axle trailer. There are 2 annexes: one with a cabinet and sink with a tap and the other with a cabinet and a refrigerator. In the main room, an electric thermal bath is installed, as well as a table and folding benches for 4 people. Inside the trailer there is an electrical installation (roof lamp, switch, 1 double socket, electrical connection and 230V fuse box).
