álvaro siza has completed a riverside art gallery in northern portugal, which has been elevated above the ground to protect against potential flooding. the nadir afonso foundation, located on the banks of the tâmega river in the city of chaves, has been constructed using white concrete walls, punctured with carefully positioned openings to provide natural light.

the main floor of the nadir afonso foundation — named after the geometric abstractionist painter — is positioned on a concrete plinth at a height of 3.5 meters. this platform is supported by concrete walls, and is accessed via a gently inclined ramp. the program is divided among three primary sectors: the atrium, which includes the reception, a library, and a 100-seat auditorium; exhibition spaces, which are subdivided into three longitudinal wings; and staff and administration areas, contained within the upper part of the building.

the main exhibition room, which can be asymmetrically subdivided in two, includes a continuous clerestory window. meanwhile, the exhibition room in the southeast wing is illuminated by a horizontal opening over the river. wooden flooring extends throughout the museum building, with white plasterboard cladding the walls and ceilings. interior window frames are made of wood and stainless steel, while the exterior ones are made of wood and aluminum.
