Castellana 77


Castellana 77 is an office building with a highly distinctive aesthetic, at the cutting edge of sustainability.

Its design has become a landmark in the urban landscape of Madrid. 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 the building greater visibility, making it stand out in this business district.

The building holds Platinum LEED certification in the Core & Shell category awarded by the US Green Building Council (USGBC), one of the most prestigious international certifications recognizing the sustainable behaviour of buildings. 

Castellana 77 has obtained WELL Gold in the category Core & Shell, making it the second office building in Madrid to achieve this distinction. WELL is the first global certification for buildings focusing solely on human health and wellbeing. 

Moreover, Castellana 77 has attained 5-star AIS certification (Accessibility Indicator System) and become the second office building to hold the highest level of this accessibility certification. 

Castellana 77 has won the award for Best Office Architecture Spain 2017-2018 at the European Property Awards Architecture and a Special Mention in Architecture at the German Design Award 2019.

Castellana 77 has obtained WELL Health-Safety Rating certification.

WELL Health-Safety Rating was created based on feedback from the COVID-19 Task Force at the International WELL Building Institute (IWBI).

This certification process entails an evidence-based adoption and monitoring of a plan of measures to assure that the operation and maintenance of the building complies with health and safety standards required by the rating in the current COVID-19 global health crisis and in the long term.
