 In the beginning of the 1980s he commissioned Nicholas Grimshaw  to construct new factory buildings and develop a master plan for the company premises after a fire had destroyed a large part of the facilities.Inspired by his acquaintance with Frank O. Gehry in the mid-1980s, however, Fehlbaum departed from Grimshaw's plan for a unified corporate project in favour of a more pluralistic approach.Since that time, buildings have been erected on the Vitra grounds in Weil am Rhein by a wide-ranging group of architects, including Frank Gehry  (Vitra Design Museum and Factory Building, 1989), Zaha Hadid  (Fire Station, 1993), Tadao Ando  (Conference Pavilion, 1993), Alvaro Siza (Factory Building, 1994), Herzog & de Meuron (VitraHaus, 2010), and SANAA (Factory Building, 2011).
