The PERSPECTIVE MADRID Office has been appointed to lead the process of refurbishment of an early 20th Century building located in Los Jerónimos quarter, one of the premier financial districts of Madrid. The 3,500m² listed building is owned by SALSA Patrimonio SL, a rental real estate company, and has been used as office space since 1992 when it was fully refurbished, hosting the headquarters of a well-known advertising company. SALSA Patrimonio has selected, after a short competition, the Perspective Madrid office proposal to update the architectural and technical elements of the building, to fulfill new code and technological requreiments. The project includes a new design for the main access and common areas, as well as solutions for the rental office spaces. All the building’s listed elements, such as façades, interior courtyard and staircase, will be fully restored to bring back their original conditions. New elements such as elevators and working spaces will be refurbished following patterns of technological efficiency for systems and construction materials. The work on site will last six months and will transform the building into a state of the art office space.
