A seafront auditorium in southern Spain has concave walls that resemble the deflated cheeks of someone taking a deep breath (photographs by Julien Lanoo).

Designed by Barcelona-based architects Estudio Barozzi Veiga, the Auditorium and Congress Palace Infanta Doña Elena provides a hall for theatre and concerts in the town of Aguilas.

Located on the seaside promenade, the building provides sheltered terraces within recessed balconies.

Two large rectangular windows on the south facade offer sea views from the central lobby and stairwell.

This auditorium is the second sea-facing building featured on Dezeen this week, following a cliff-top house in Sydney inspired by a Picasso painting.

Other auditoriums recently featured on Dezeen include a convention centre crowned by a ring of mesh thorns and a performing arts centre resembling a pair of shells.

The project is a natural response to the particular stimulus, offered by the location.

On one hand the need to respect the urban tissue that growths inside, on the other, the one’s to preserve the expressive hue of the natural landscape.

It is through from this contrast, that we define and articulate tensions which allows the project to organize itself while a coherent response to the constraints of place.

The building is a dialectic reflection, simple but at the same time strong, between the urban artificiality and the organic naturalness.

Thus, the building results in a large mass, shaped in function of the tensions that proceeds from the different character of the spaces surround it.

Tangent to the town, the facades are clean, orderly and paused, while tangent to the sea, the facades translate the surrounding space and the configuration offered by the landscape and geography, through large and concave surfaces, that provides a direct and intensive relation with the surrounding natural environment.
