Spanish architect Alejandro Valdivieso has repurposed a former water cistern near Madrid, transforming it into the basement of a house with a glass facade that curves around the original well.
Casa Aljibe, which translates as Cistern House, is situated in the suburban district of Alpedrete, northwest of the Spanish capital. The underground cistern was built early in the 20th century and was originally connected to a well that supplied water to local properties.
The south-facing plot is covered with scrubland vegetation typical of the hilly region, and the original building was constructed with an unusual plan that follows the topography of the rocky ground.
A metal framework supports walls made from prefabricated timber panels that enclose an open-plan living space comprising a lounge, kitchen and dining area.
