The Sidera building (CIA Conad Headquarter) extends horizontally for a length of 100 metres and has a height of 33 metres, starting from a soil plinth that is approximately 3 metres high. The external surface features only three materials: aluminium, black pigmented concrete and glass. The natural aluminium plays the leading role as it elegantly reflects the natural light, taking on different nuances of tone and colour at different times of the day and weather conditions. In a context that is devoid of identity, the Sidera has been conceived to be a new element to add to its surroundings.
