An old warehouse occupies the heart of an urban expansion of Bilbao that is accessed by a tunnel that crosses the residential junctions. There, a program is deployed, composed of premises for storing and handling works of art, administrative and meeting areas, spaces for experimentation and specific projects, and a large central room that is the centre of the program. The architecture embraces what a few materials offers —exposed concrete structures, continuous industrial flooring, white walls levitating over recessed baseboards, some furniture— to construct the basic ingredients of an exhibition space —floors, walls and ceilings— in which the works of art are given the responsibility for characterising it. The reinterpretation of the original system of skylights generates a series of light capture devices similar to periscopes. Their volumes generate on the roof of the warehouse a new industrial landscape given to the city that stitches together the past, present and future of a surprising place.
