The Prudential Insurance Building, now the Hotel Warszawa, was the tallest building in Warsaw when the tower was erected in the 1930s. The building suffered greatly during the Second World War, and was totally gutted by shelling. However, its steel skeleton refused to topple, and following the war it was rebuilt to Socialist aesthetic values.

The refurbishment of this iconic building includes the modernisation of the 16-storey tower, construction of a new 7-storey building behind it, and covering the atrium between them with a glass roof. The higher structure will feature luxury apartments and the rest of the complex will be the hotel.

One of the key elements of the restoration is the preservation of the listed steel structure.
