Casa RO by Elias Rizo Arquitectos is located in a well stablished residencial area. This house built in the 60’s, with its straight lines, honest distribution, communication with the exterior, and usage of materials, represents the architecture of its time. All these hints help the author decipher the project and set in motion arduous work of intervening while respecting its essence.The project consists in the restoration of the old house, which was really deteriorated. The house had several failed previous interventions, but there was a lot to rescue. It begins with the demolition of some of the adjacent areas, maintaining almost all the original flooring on the ground floor, mainly because of all the new installations. It´s all about precise work demanded by these particular clients: a young family with a unique way of living and perceiving architecture.
