page title icon The Urduliz tower is transformed into a state-of-the-art skyscraper

An emblematic building in Uribe Kosta that after its recent refurbishment will be used as a business and office building. It is one of the most self-sufficient buildings in the Basque Country due to the implementation of geothermal and photovoltaic energy.

Maratek participated, hand in hand with Aecom, in the development of the mechanical and electrical installations of plants 7, 8, 9, 10 and 11 of the tower, as well as in the drafting of the corresponding Activity Report for its commissioning. After a refurbishment process started in July 2016, the tower is now finalising the details to officially open its doors.

The complex covers a surface area of 7,907.15 square metres and rises over fourteen floors whose transformation and modernisation has involved an investment of around six million euros. It incorporates innovative technologies and highly energy-efficient, sustainable and environmental applications.  “It is one of the most self-sufficient buildings in the Basque Country thanks to the geothermal energy we have incorporated and the photovoltaic energy”, stresses Asier San Nicolás, manager of Urdulizko Industrialdea.


Of its fourteen floors, a dozen are destined to offices which have toilets on each floor and occupy a total surface area of 4,848 square metres. Each of the offices is tailored to the specific needs of the companies and offers shared modular spaces ranging from 45 to 540 square metres.

On the other hand, the ground floor consists of a spectacular access hall of 167 square metres where the common areas and offices of Urdulizko Industrialdea are located, as well as a meeting room for rent of 50 square metres. In addition, the building has two lifts, a main staircase and an emergency staircase providing access to each floor. Entry to each floor is by swipe card.
