The design, as now being constructed, is based both on reconstructed versions of the lost plans and on modern adaptations. Since 1940 the architects Francesc Quintana, Isidre Puig Boada, Lluís Bonet i Gari and Francesc Cardoner have carried on the work. The current director and son of Lluís Bonet, Jordi Bonet i Armengol, has been introducing computers into the design and construction process since the 1980s. Mark Burry of New Zealand serves as Executive Architect and Researcher. Sculptures by J. Busquets, Etsuro Sotoo and the controversial Josep Subirachs decorate the fantastical façades.
