Each year during the London Design Festival a host of international design talents are invited to create installations and interventions within the hallowed halls of the city’s Victoria and and Albert Museum. This year’s undisputed show-stopper is London design duo BarberOsgerby’s monumental ‘Double Space’ installation - a six-tonne, 11m x 8m design comprising two gigantic revolving ‘reflectors’ that were designed and made in collaboration with BMW.

Installed in the lofty Raphael Gallery, the kinetic sculpture transforms the space into a hall of mirrors, distorting the Raphael Cartoons (full-scale designs for tapestries, painted by Italian Renaissance artist Raphael) and changing the way in which visitors experience the room. ’We wanted to create something that would be an experience, not just something that’s static but something that would hold your attention for a while,’ explains Edward Barber. This short film offers a behind-the-scenes glimpse at the 11 month-long design process, from initial concept sketches and model making right through to the final stages of its construction and eventual public unveiling.
