Parisi Udvar, the Parisian Courtyard in English, is a prominent hotel situated in the heart of Budapest, originally constructed between 1909 and 1912. The structure of this building is considered the first of its kind to be constructed and designed from reinforced concrete, following the same methods used today. From 2015 to 2019, the building underwent deep level renovation to perform new functions. Due to the original design of the building that was deemed unsuitable to withhold today’s demands, and in order to fulfil its special requirements, our company went back in time to the 19^th century and joined minds with its original engineer that designed the building.
