 The steel frame of the building was made in Germany and is based on a model made in the early 1880s in Chicago to increase fire resistance. It was erected by Messrs Potts & Co. of Oxford Street. Fireproofing of the walls were conducted by the Columbian Fireproofing Company Ltd. of Pittsburgh and London, with steel-ribbed bars allowing for ventilation, while remaining sound proof and free from vibration. The internal walls consist of "hollow, porous, terra-cotta blocks" covered with plaster, and the hotel's flooring was also made fireproof. At the corners of the pavilion roofs of the Ritz are large green copper lions, the emblem of the hotel.
