This masterpiece by Sáenz de Oiza and of Spanish architecture of the 20th century, is located in the most privileged area of Madrid’s financial hub and, following an ambitious renovation plan, it looks to the future as a symbol of sustainability, accessibility and technology.

At the end of 2016 the work on the interior of the 23 office floors that BBVA had left vacant a year before was completed. Renovation on the top 5 floors, occupied by BBVA until the end of 2017, started immediately after it vacated the premises and work was completed in April 2018. ROOFTOP 5, the name given to these top floors, is one the most exclusive spaces in the Madrid office market.

Renovation on Castellana 81 included the creation of a full service floor, including an auditorium with a capacity for 188 people, equipped with state-of-the-art technology, 8 meeting rooms fitted out with cutting-edge technology, physiotherapy service, showers and changing rooms. In 2017 the value-added services offer for clients was extended by installing Wi-Fi in the common areas: lobby and car park.

In March 2017, Castellana 81 became the first building on the Paseo de la Castellana to be awarded LEED Platinum certification in the category Core & Shell, the highest distinction awarded by the US Green Building Council (USGBC).

At the end of 2017 it achieved DIGA (Hallmark of Level of Accessibility) five-star certification. This makes Castellana 81 the first singular office building in Spain with the highest accessibility level.

In May 2018, Castellana 81 became the first WELL office building in Spain and the fifth in Europe to achieve Gold standard WELL building in the Core & Shell category. WELL is the first international certification for buildings that solely focuses on human health and wellbeing.

In 2018, after renovation, Castellana 81 received a series of awards: “Prize for best renovation 2017” from the AEO (Spanish Office Association)-. “Best Non-Residential Project” in the ASPRIMA-SIMA awards. “COAM Award -Madrid Institute of Architects- 2018” for its renovation.

In January 2019 the building was declared a Heritage Asset in the monument category. It is the first time that a building of recent construction has been protected as a Heritage Asset in the Madrid Region.
