Transportable room expansion hall
The transportable room expansion hall was a flexible system developed and manufactured in the GDR to temporarily provide permanently roofed rooms with a maximum length of 16 meters and around 128 square meters of floor space . It is an excellent example of mobile architecture .
The idea goes back to Helmuth Both, who presented the first drafts in 1959. After further development by his son Klaus Both, it went into series production from 1966 under the name "Variant".
The room expansion hall (REH) consists of a maximum of eight room elements, called tunnels, which can be telescoped into one another. Its outer shell is a construction made of sheet aluminum and light steel girders, the inner walls are clad with hardboard. The floor is laid separately on rails. Two such systems can be easily enlarged to form a hall about 32 meters long. Because of their construction, the transportable space expansion halls were popularly referred to as the "accordion". When folded, it has roughly the shape of a caravan and is therefore transportable.
The room system could be set up flexibly as required on village squares, in gardens or in public spaces. It was used, for example, as a department store and post office , canteen , as a workers' or holiday home, restaurant , ice cream parlor or cinema . No more than six people and no other aids were required to set up a 16-meter module.
In the company of the inventor Helmuth Both in Boizenburg (later VEB Metallbau Boizenburg) around 3500 room expansion halls were built by 1989. Today only a few copies exist.
