Located on a privileged corner of Madrid’s Salamanca district, between Juan Bravo and Núñez de Balboa streets, this project begins with a neoclassical building with partial protection status, whose façade, entrance hall, and staircase are essential elements of its historical and urban identity.

The starting point presented a compositional and urban challenge: to integrate the building’s growth within a consolidated context, surrounded by taller adjoining buildings, without losing the harmony of the whole. The intervention was based on a careful reading of the context, unifying the color and tones of the façade in dialogue with neighboring buildings and resolving the entrance to the parking garage in a discreet way, coherent with the original composition.

From a construction perspective, the project involved a highly complex technical intervention. The complete stabilization of the protected façade and existing staircase was required to enable the interior renovation, as well as the precise integration of the new upper volume.

Below ground level, four basement floors were developed for parking and communal areas, executed through secant pile walls and micropiles around the entire perimeter of the site. These were built directly adjoining the protected façade and neighboring buildings, with excavation works carried out in a particularly sensitive context due to the proximity of metro tunnels.

The residential program comprises 15 homes, with typologies ranging from two to five bedrooms, designed to offer spaciousness, spatial quality, and comfort in one of the city’s most sought-after areas.

Núñez de Balboa 86 is a comprehensive intervention that exemplifies the ability to integrate heritage, engineering, and contemporary design, precisely resolving a complex urban and construction challenge to create a solid, elegant residential scheme, fully integrated into its surroundings.
