Casa 17
Casa 17 is a minimal home located in Madrid, Spain, designed by KAL A. Originally part of the southern expansion of Madrid in the late 19th century (as part of the Castro Plan), this 75-square-meter house underwent an interior renovation aimed at preserving the identity of the 1927 building in which it resides. The home had been altered multiple times throughout the years, erasing much of its original character. However, during the demolition process, the discovery of original ceramic tiles became the foundation of the renovation’s design.
These terracotta red tiles, sourced from the small village of Arcos de Jalón in Soria, are a nod to the area’s railway history, as the village once played a key role in connecting Madrid and Zaragoza by train in the late 19th and early 20th centuries. Where possible, the original tiles were restored and used throughout the house. They now feature prominently in the entrance, bathroom, laundry room, and on the two terraces. For the rest of the flooring, a smooth cement surface was chosen to contrast with the terracotta tiles and create a neutral backdrop for the living spaces. The renovation also focused on improving the spatial flow and natural light.
The previously compartmentalized layout was streamlined, reducing the number of rooms to create more open and expansive living areas. The kitchen and living room are linked by a structural wall with three symmetrical openings, allowing fluid movement between the spaces while maintaining a degree of separation. The kitchen was custom-made in KAL A’s workshop, featuring a modular system of solid cherry slats that can be easily adapted over time. Designed for flexibility, the kitchen accommodates future modifications, ensuring it evolves alongside the household’s needs.
