Bilbao, Miribilla neighborhood, built on ancient iron mines adyacent to the old part of town. A very hilly solar (46 m from one corner to another, just 200m) in which the building was caught in the neighborhood park.
Limestone rocks sticking out between the banks and trees in the park gave us the key to design and resolve the complex functional and circulation program: use of simultaneous game day sports use, use of court by the neighbors, access to players, officials, public premises for a possible lookout restaurant, sports center with a separate entrance but with access to track so that residents can use the court when there is no match, parking connected to both spaces, etc …
We divide the building into two.
The Arena enclosure at the top with the tickets away from houses to avoid the possible inconvenience of excessive noise of the followers of Bilbao Basket.
The sports center at the bottom, closer to homes.
The Bilbao Arena was designed as a tree, tree-pillars that brace the elements in the metal structure façade and painted steel sheets in various colors to build an air-permeable end that hides all the machines in room climate.
The sports center was designed as a rock, precast concrete panels textured and colored in the mass of the color gray limestone of the area. A hollow rock in which the three spaces of sports communicate visually, in stages, in cascade: access to parking, gym and swimming pool. Panels lined with green, the color of moss. And the arboreal mass about Billbao Arena over the rock.
The facade of the Bilbao Arena in the area of the corridors, the rings, the sum of the limited budget and a clear focus on low power, is designed permeable, resolved with a galvanized steel mesh is used for containment of slopes roads. Thus the space of the corridors, is an outdoor environment that requires no ventilation or air conditioning and increases safety in evacuation in case of fire. When the viewer opens the door vomitory already on the street and thanks to this permeability and high elevation of the citycenter become a viewpoint.
In the bathrooms again the strategy of the permeability: a closure plate perforated minionda ensures privacy and natural ventilation ducts or without ventilation equipment.
Inside the pavilion is coated sand minionda entirely perforated plated, galvanized or lacquered, according to areas and rock wool. Vandal-resistant enclosures and get a good performance and absorbents that have enabled phone a perfect intelligibility of PA systems.
In one corner of Bilbao Arena in the highest level, that of the tree, leaves, provided for the local hospitality, with a core of vertical communication with two lifts and completely independent of the rest, to enable operation at different times. A generous balcony or terrace occupies behind the veneer in place dealing with the other facades of air conditioning machines. To enable the views of the city by simply removing a few leaves, not a Cartesian gap.
The sports center has a pool and gym and management office complex.
The divisions between the various gyms and between them and the pool are made of glass, including the connecting corridor with parking. The aim is that the building is safe for the user, without dark corridors, and visual control by staff: everything in sight.
Everything inside the sports center is coated with an absorbent fiberboard phone, green. A large skylight in a corner of the pool, introduce natural light to illuminate the green signs would point to the green light we see when we dive in ponds or streams or caves.
The cover sports is a vegetable, green, an indoor cistern that stores rainwater, which retrieves the plant substrate by capillary action and makes irrigation unnecessary.
The pool water that the law requires waste, 5% per day, a lot of gallons for a pool of 25 m and 7 streets, stored in the basement in a cistern, where trucks that clean the streets of Bilbao refuel reused.
The machine sports conditioning and ventilation are located in a large covered patio with a Tramex (see cross section) between the pavilion and the sports arena. It is easy maintenance and unnecessary noise pollution and visual environment to housing.

+ About ACXT
ACXT, an architecture services provider, started off as a society of professionals who came together with the aim of offering a quality alternative within the field of architecture, becoming a valid option for the professional development of architects interested in high level architecture. Its philosophy marks the creation of a professional framework of collaboration and avail of its members’ synergies, always from a full understanding of architecture: both technically and culturally.
ACXT emerged linked to IDOM group, as an extension in the world of architecture of the principles that inspired its foundation and continuing functioning for over forty years. In an attempt to exceed the existing offer on the market, its work covers from the architect’s studio model to that of the services company.
The philosophy that guides ACXT is based on the respect for traditional values, still in force today, generated during the secular practice of architecture. ACXT is committed to signature architecture, understood in terms of respect for the creative values that architects, with a clear customer orientated practice, have historically contributed throughout the whole intellectual and constructive process. ACXT aims to offer a quality solution to the huge social credit that the practice of architecture implies in its double commercial and cultural dimension.
ACXT-IDOM has become the largest provider of professional services to architecture in Spain and one of the most relevant worldwide. In the January 2010 edition of the BD World Architecture’s Annual Survey, a British publication that gathers the hundred most important architecture firms worldwide, ACXT-IDOM was ranked number 37, rising ten positions since the previous issue in January 2009.
In 2009, the Board of Architects’ Associations of Spain (CSCAE) awarded ACXT the “Professional Practice Methods” Prize, within the competition Experience/Futures. This contest tries to spread the quality and variety of the professional work that architects in Spain carry out, whether it be individually, in groups or multidisciplinary teams.
Throughout its professional career, ACXT has gained recognition from many organizations, public bodies, professional associations, etc. By way of overview, it is worth mentioning the various FAD and ENOR Prize finalist works, the participation, on repeated occasions, in the Spanish Architecture Biennial and the mentions and awards won in the majority of Architects’ Associations in Spain.
