Recent architectural projects have focused on the restoration and rehabilitation of historic residential properties. In El Salvador, the Casa Quiñónez, a 1918 neoclassical and Art Nouveau residence formerly owned by President Alfonso Quiñónez Molina, has been noted for its significant architectural elements, such as ornamental ironwork and four Corinthian-style pillars, despite long-term neglect.

In Spain, various renovation projects aim to modernize historic spaces while preserving original character. These include the transformation of a 1900s apartment on Calle Serrano, designed by Estudio Hilera, to increase natural light and create an open-plan living area. In Alcalá de Henares, the renovation of Casa BC, a 1960s military complex apartment by Estudio Casabona, utilizes original textures, checkerboard parquet, and a repurposed dark green terrazzo wall. Additionally, the conversion of Cal Moliné - Arrels, a former stable in the Berguedà region, into a country house maintains its traditional stone facade while improving connections to the landscape.

Further rehabilitation efforts in Spain include the adaptation of the 150-year-old former San Juan Bautista Asylum into the Universidad Europea de Valencia campus, a project documented in the book “Campus Turia. Del mosaico Nolla a los nuevos espacios universitarios.” In Ortuella, Vizcaya, a 1902 building with protected facades underwent energy rehabilitation, reducing energy consumption by 92% through improved insulation and a decentralized mechanical ventilation system.
