This project for an office building on Castellana Avenue in Madrid focuses on the preservation and restoration of its listed historical elements. At the same time, its design optimizes the new interior work areas from programmatic and environmental points of view.
The intervention preserves the listed elements of the building. These include its façades, the main staircase and its lobby with access from Paseo de la Castellana. The proposal includes the excavation of four new floors below ground level. Likewise, the project increases the buildable floor area by approximately 20% over the current area of the property.
The main staircase becomes the triggering point for the location of a new central void or main courtyard. This void ensures adequate lighting and ventilation conditions for all future work areas.
The large polyhedral copper roof, treated as a third façade, becomes an extension of the traditional elements of the façade. Through the combination of metal sheet and mesh, it allows for the regulation of natural light and generates open-air spaces. These new terraces make the most of the ideal location of this new office building on Castellana Avenue.
