Bilbao today is a prime example of urban restructuring, having transitioned from an industrial city to a city of services and culture.

Discover the urban evolution of Bilbao visually and intuitively by taking a historical look at the most relevant projects undertaken in the process.


In project

Bilbao's transformation has no start and end date, but rather is an ongoing process.

Learn about the projects that will become the new landmarks to consolidate Bilbao as a leading city in urban planning and architecture.


New constructions

For some time now, Bilbao has been unveiling significant urban and architectural novelties.

This section will provide full detail of recent endeavours which are already a part of the New Bilbao.


Heritage buildings

Bilbao has taken great pains to preserve its heritage as much as possible, making renovating and preserving Bilbao's historic buildings a key aspect to combining the new architecture with that of inspired artists of yesteryear.



Modern architecture has raised twenty-first century Bilbao off the ground. As great national and international architects -many of them recipients of the prestigious Pritzker Architecture Prize- left their mark in the form of modern works of art.The city's commitment to world-class architecture is self-evident and has been successful.

Surface: 3.660 m² (above ground), 1.821 m² (underground)

The project, intended to house the new headquarters of an energy company, is part of a building listed as Basic Protection for the Urban Plan of the city, which undertakes to maintain the facades and elements of heritage value.

We opted for complete emptying of the internal structure, spatial characteristics on dimensions, heights easements useful and patios are inconsistent with the objectives of the client, who emphasizes the need for a flexible, versatile and modular, capable of adopting, in the present and the future, different distribution configurations, minimizing conditions derived from the processes of transformation.


The new spatial organization is based on the idea of introducing light into the building through an irregular glass vertical prism, as a patio, whose shape is metaphorically the vortex of a tornado is introduced into the internal structure the building, referring to a force of nature that is another form of energy.

The design of the structural framework is posed as one of its priorities, to free up the floor space of each floor, trying to generate the least servitude resulting from the presence of pillars and beams in the face of the functional organization and to facilitate tracing premises networks.

The carrier system comprises a large cross, formed by two metal beams large sing, lattice, arranged orthogonally to the level of the two floors, supported by two large concrete caissons, by way of brackets, which are capable of house elevators and vertical and horizontal stability to the whole. The structure of the rest of the plants is suspended from this element through a single main strap.

Thus the set of each plant is completely transparent, especially on ground floor, which rests on forged basement structure and need not, therefore, no visible vertical structural element, except for the two concrete cores.

The solution consists of being introduced project a new box inside the box formed by historically required the facades of conservation. Space and space between the inner courtyard spaces are treated as bioclimatic able to behave interactively, through mechanisms of control domotizados sunlight and natural ventilation to promote uptake or heat dissipation, control and optimization of input light natural and, together, improving the environmental conditions of the user.


Reducing energy demand seeks the design of these systems and the use of renewable energy to meet part of the residual demand, based primarily installed geothermal probes, minimize the need for conventional installations, selected criteria maximum efficiency.

The installation of smart lighting and other measures contribute to the high energy efficiency, which reaches the highest rating (Class A). The eco-design methodology adjusted to a management system approved, contemplalas measures in relation not only with energy consumption during the use and maintenance of the building, but also those relating to the consumption of materials, water, and management waste so that the building is certified with the highest rating under the American standard green LEED agency overseen by the U.S. Green Building Council.



La instalación de sistema inteligente de iluminación y otras medidas contribuyen a la alta eficiencia energética, que alcanza la máxima calificación (clase A). La metodología de ecodiseño, ajustada a un sistema de gestión homologado, contemplalas medidas necesarias en relación, no solo con el consumo de energía durante la fase de uso y mantenimiento del edificio, sino también las relativas al consumo de materiales, agua, y gestión de residuos de tal manera que el edificio se certifica con la máxima calificación verde conforme al estándar americano LEED, tutelado por la agencia U.S. Green Building Council.
