Architects behind multi-million pound Royal Academy regeneration in contention to remake the National Gallery Robert Dex The architects behind the multi-million pound Royal Academy regeneration are in contention to do the same for the National Gallery. The David Chipperfield firm is one of six design teams shortlisted to work on the £30 million makeover planned for the gallery’s bicentenary in 2024. The list is completed by David Kohn Architects, Selldorf Architects and Witherford Watson Mann with a final decision on the design team due in July. National Gallery Director Dr Gabriele Finaldi said: “We were impressed and delighted with the high quality of the submissions we received. It was not an easy task to reach the shortlist, but we are confident that we have chosen six teams that will produce a range of different approaches to excite and inspire us.
