oxxeo stands out for its sustainable and avant-garde design, created by the prestigious international architecture practice RAFAEL DE LA-HOZ.

It is a freestanding building, with a triangular floor plan, following an innovative architectural concept that takes the load-bearing structure to the outside of the building forming a latticework, which in turn protects the façade from direct sunlight. This design maximises space on the office floors and leverages natural light.

oxxeo users can enjoy a rooftop equipped with two individual paddle tennis courts, jogging track, outdoor exercise area and rest area.

With a surface area above ground covering 14,299 m², distributed over five floors, oxxeo provides 450 parking spaces on two underground floors, which include spaces for electric vehicles, fuel-efficient vehicles and bicycles. The new development has green areas, with landscaping and street furniture and a drop off point for taxis and cars.


The office floors, each covering 2,945 m², are highly efficient and flexible and with a floor to ceiling height of 2.7 metros. The ground floor of the building, covering a space of 2,518 m² and 4.0 metres tall, is equally suitable for office or commercial use.

Designed with environmental responsibility firmly in mind, the building already holds prestigious Platinum LEED certification, the highest distinction awarded by the US Green Building Council (USGBC) and it has initiated the WELL Building Standard certification process for Core & Shell. Moreover, the building holds an A energy rating.

As part of oxxeo’s commitment to accessibility and a diverse society, the building has attained the top level 5-star DIGA certification (Hallmark of Level of Accessibility).

This makes oxxeo the first newly constructed office building in Spain to be awarded the highest level of DIGA certification for disabled people, senior citizens and pregnant women.


oxxeo is the first office building in Spain to deploy a Dynamic lighting system adapted to the circadian rhythm of people working there.

This lighting system incorporates a dynamic light that automatically changes the light temperature (the colour of the light) throughout the day, mimicking the natural rhythm of day and night that our bodies respond to. LED technology enables light to be regulated from warm light (incandescent type-yellow) to cold light (fluorescent type- daylight-blue).

The circadian rhythm or biological clock of people synchronises with the daylight, which changes colour depending on the hour. People “activate” at the beginning of the day and “deactivate” at the end of the day to get ready to sleep.

Founded in 1920 and led for over twenty years by Rafael de La-Hoz Castanys, this practice is one of the most active and internationally acclaimed studios in Spain. It undertakes a full range of architectural projects and its work stands out for its quality and technological innovation.
Respecting city growth and the environment at all times, it has obtained the highest sustainability rating, Platinum LEED certification, for a number of its projects and won a multitude of national and international awards. These include the MIPIM Award, the International Project Award at the Argentina Biennial or the American Architecture Award from the Chicago Athenaeum (USA). One of its recent projects has been nominated for the Mies Van der Rohe, European Union Prize for Contemporary Architecture.
Its most important buildings are largely the result of winning international architecture contracts. Apart from a host of residential projects, its latest and most representative work includes the following: the Universidad Popular de Alcobendas (Espacio Miguel Delibes), the Rey Juan Carlos I University Hospital, the Repsol Campus Corporate Headquarters, the Daoíz y Velarde Cultural Centre, District C Telefónica Headquarters, Endesa Headquarters, the ‘Pórtico’ building, the Hercules Towers, ‘Rafael del Pino’ Foundation Auditorium, the Headquarters of the Higher Council of the Chambers of Commerce, the Spanish Olympic Committee Auditorium, the Garrigues Headquarters and the business park Parque Norte.

”As the old adage goes, architecture may be just the result of building an idea.

This mythification of the idea means architects tend to provide elaborate conceptual explanations using metaphors regarding green, smart or transparent buildings.

This is not the case here and we would simply like to highlight that the idea behind oxxeo is the building itself. In other words, the idea here consists of its structure, or rather the construction of its structure, or the glass features of its façade and joints that generate its architectonic form.

In simpler terms, the architecture of this building is the result of selecting the right available materials according to building logic.

This logic has also allowed for greater freedom in terms of interior structural elements, displaying them on the outside and enhancing the building’s singularity.”
