The tallest tower in Spain at 250 meters, Torre de Cristal stands prominently within the Cuatro Torres Business Area north of the city center in Madrid. This expanding financial district contains Spain’s four tallest towers, giving the business park its name. The towers are arranged along the Paseo de la Castellana, Madrid’s main north-south thoroughfare. Spaced apart to allow distinct views of each tower, the buildings re-define the skyline of Madrid.
Like a shaft of crystal, Torre de Cristal has an angled, sculptural form. The building’s facets reflect the sky, giving life and movement to the structure. The top level of this 50-story office tower contains a winter garden, a vertical space on the west interior wall. Lit at night, the winter garden is visible along the Paseo de la Castellana and throughout northern Madrid.
Building amenities include a fitness center, meeting rooms available to all of the building’s tenants, and two restaurants, one on the ground floor and one on the mezzanine. Parking is below grade.
Among the building’s energy-saving features is the high-performance, ventilated double-glazed curtain wall, the largest low-iron-glass installation in Europe at the time of the building’s construction. The curtain wall includes integrated blinds controlled by a central computer to automatically adjust according to natural lighting levels, conditions and HVAC usage. In addition, the roof has photovoltaic cells to heat water for the building.
To create a comfortable environment for the building’s occupants, no office is deeper than 9.5 meters (31 feet), enabling all workspaces to receive natural light. Energy-efficient under-floor air delivery allows for localized adjustments to heating and cooling, further increasing comfort.
