Kalam took different structural measures according to the deterioration of the buildings to be treated in this neighborhood of Madrid. Many were reinforced with micropilings in the exterior and the interior because of ground conditions. Plumbing chambers were created and isolated from the outside of the façades, replacing all the woodwork. The roofs were also renewed and waterproofed. As in other areas of the rehabilitation, entrances were adapted and elevators were installed, changing the entries to the sites.
