a new fourth floor and plant room above. Planning permission was granted and work began. The chief contractor was Bovis, who worked on the shell and core. Conran Roche worked on the interior of the new Conran Shop, and YRM worked on the interiors of the Octopus Publishing offices. Conran Roche and YRM had to search for suppliers to recreate many of the building's original features. The three stained glass windows which had been removed for safety during the Second World War had been lost and the glass cupolas at the front of the building had disappeared. After a long search, suppliers were found, and replicas of the windows and cupolas were made using original drawings, photos and posters. In August 1987, Michelin House re-opened. In the late 1990s, Reed/Octopus Publishing moved out. In 1999, Monitor Group, an international business consulting firm, moved into the office space. 20 January 2011 marked the 100th anniversary of the building's opening. The event was celebrated by the building's then occupants, Bibendum Restaurant and The Conran Shop, and the former owner, Michelin. As part of the centennial, Michelin has renewed its efforts to find the original stained glass windows. A stained glass amnesty website and hotline have been set up for this purpose.
