Castellana 77

Located in AZCA, the financial centre of Madrid, the building was acquired by Gmp in February 2015 and full renovations on the building began in October of the same year and were completed in May 2017.

The acclaimed international practice, luis vidal + arquitectos, carried out the renovation project, which completely transformed the original building; giving it a highly distinctive aesthetic and placing it at the cutting edge of sustainability. In fact, in 2017 it won the “Award for Best Office Architecture Spain 2017-2018” in the European Property Awards Architecture. At the time of writing this report, the building has also received a “Special Mention” in the German Design Awards 2019.

The architectural approach to the façade is worth highlighting as not only does it represent an aesthetic achievement but also enhances the efficiency and sustainability of the building through adding slats that protect against direct sunlight. The option of these distinctive slats being lit up at night, gives Castellana 77 greater visibility, making it stand out from its surroundings.

In 2018, the range of value-added services for clients of the building was extended through the installation of Wi-Fi in common areas: lobby and car park.

In the framework of Castellana 77’s commitment to accessibility, it achieved DIGA 5-star certification (Hallmark of Level of Accessibility) in April 2017 and became the first office building in Spain with the highest level of accessibility in the Built-up Surrounding category for properties built after 2010.

At the time of writing of this report, the building holds LEED Platinum Pre-certification in the Core & Shell category, the highest distinction awarded by the US Green Building Council (USGBC).

In addition, Castellana 77 was one of the first properties in Madrid to register for the WELL Building Standard certification process, the first international certification for buildings that solely focuses on human health and wellbeing, and it aims to complete this process in 2019.
