A building is an act, said Louis Sullivan, implying that it had a moral as well as an aesthetic obligation. Well I think it is true because in each creation we change a way to live. The Terra Project is for me the opportunity to change the way to build a Tower. On the West side of the Terra Tower there is a wall with only two columns of windows. This wall is an act, the act to say I am here standing alone. It is an act of proudness or an act of vanity. But it is clear, the Terra Building stands alone. Thats the whole pointthe sitting.
