recently completed, the auditorium and performing center ‘el ‘B” designed by madrid-based practice selgascano is placed along
the docks of the harbor city of cartagena, spain. spanning the 1 kilometer long alfonso dock, a 20 meter void between the building
and water serves as a promenade, maintaining the artificial waterfront of the port. the translucent exterior of the linear volume
stretches 210 meters and projects the orthogonal edges found in the man-made environment. as visitors enter the interior,
a delicate and light space is presented, evoking a soft aquatic ambiance that is decidedly missing from outside the building’s walls.

aluminum and plastic manufactured from a single extruded section are placed in diverse ways and tinted with pigments
to appear as different elements. set parallel to the pier’s edge, the horizontality of the low-profile facade accentuates the structures length,
with a roof terrace offering panoramic and unobstructed views to the sea.
