Hotel | 27 sqm | 17 kW_th | 1999

The hotel „Die Fabrik“ is located in a former industrial building. In 1994 when the building was reconstructed as hotel rooms, bathrooms, the lobby and a restaurant were created. The increase of comfort standard was not to manage with the 50-years-old out-of-date steam heating system. Therefore in 1999 the whole building was energetic modernised.
