Titania Tower

This new, glazed tower in the skyline of the Spanish capital shimmers in greenish shades: a shopping centre with an office tower, almost entirely made of steel. The Titania Tower was built on the subterranean structure of the Windsor Tower which was destroyed in a fire in 2005. ArcelorMittal provided steel sections and composite flooring.

The Titania Tower was built on the exact location of the Windsor Tower which was destroyed in a fire in 2005 and subsequently dismantled. Only its underground floors remained intact and were therefore maintained. It is situated in the centre of Madrid’s business district, close to the famous avenue Paseo de la Castellana.

Commissioned by El Corte Inglés and designed by the architects Pablo Muñoz and Pedro Vilata, the construction of the new building was started in 2007.

The commercial part of the complex was inaugurated end of 2011 and has now become the flagship store of the famous Spanish department store group in Madrid. The aim was to create an attractive building transmitting movement by the use of glass and perforated steel sheets for the facade.

With 103,7 m of height and a total of 27 floors (including the 5 existing underground floors used for parking), it is almost as high as its predecessor, the Windsor Tower.

The first 7 floors (ground floor – 6) are used by El Corte Ingles as a shopping centre, and offer a total of 21.133 m2 commercial space. On the roof of this volume, 2 technical floors are installed, they contain different machinery, air treatment installations, ventilators, pumps etc. They provide service to the shopping centre and the offices. Two more technical floors are introduced on top of the building, on floors 20 and 21.

The office tower rises from the rectangular basement and is completely glazed, in greenish shades and offers 14.430 m2.

According to the different function of the building, there are 2 entrances: a main entrance to the shopping centre and one to the hall of the office building.

Intelligent & sustainable

The Titania Tower was designed to be exemplary as far as sustainability is concerned. It incorporates the latest technologies that guarantee major energy efficiency, thus respecting its environment: Due to its orientation the glazed cylinder has been equipped with a system curved modular system of solar control that – at the same time – incorporate photovoltaic cells for the production of clean energy. 

Automatic light systems based on movement, free-cooling systems for the air conditioning, the use Energy saving light bulbs and systems for the efficient use of water all contribute to the reduction of energy consumption of more than 60%.

Steel structure

The new Titania Tower rises out of the 5 existing, subterranean floors, the “leftovers” of the dismantled Windsor Tower. Its structure consists, almost entirely, of steel profiles, realized and assembled by Callfer SA. Only one big nucleus that acts as a stabilizer and contains elevators and staircase and two 2 smaller ones for additional elevations and service elevators are made of concrete.

Almost all columns consist of HD hot rolled profiles, of which a total of 1.000 tonnes in grade S 460-M were used. Only a minority of them are composite columns based on HEB sections (in S 355-JR). The transition and connection between the existing concrete structure and the new steel structure is realized with steel plates (10 or 6 mm thick, in S 460-M) and tie bars made of reinforcement steel bars with 40 mm diameter and a bolting system.

The entire beam structure on all floors is made of HEB profiles of various dimensions, except some special beams made of HEM. On the 7th floor, where the shopping centre ends and the offices begin, trusses of about 2,5 m height create a cantilever on 28 m height, creating a 7 floor entrance hall. These trusses consist of HEB sections, in its top and bottom chords, as well as upright and diagonal structure. A total of 5.000 tons of beams were used for the horizontal structure on which the composite flooring was installed.

For the flooring system, more than 30.000 m2 of Cofraplus composite flooring deck (1 mm thickness) were employed on which concrete was poured, resulting in a slab thickness of 200 mm.

Steel columns beams and flooring deck were entirely supplied by ArcelorMittal.
