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.

After full renovations, Castellana 77 has become a building in harmony with the environment that prioritises sustainability in its value proposition. 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.  Its aim is to promote buildings that respect the environment, are economically viable and comfortable to live and work in.

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 and is based on seven years of scientific, medical and architectural research. 

Moreover, Castellana 77 has attained 5-star DIGA certification (Level of Accessibility Hallmark) and become the second office building to hold the highest level of this accessibility certification.  Created by the Shangri-La Foundation, DIGA certification specifically takes into account functional diversity standards, including physical, sensory and cognitive criteria, so that any person, regardless of their condition, can move about the building based on principles of convenience and safety. 

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.
