In ancient architecture and urban design of Isfahan, two concepts were common.One was Sibe(the semi-public gated dead-end),surrounded by houses accommodating relatives, and the other was courtyards(the semi-private space),surrounded by rooms housing a family.The Sibe and courtyard gave people the sky and gathered them together under it.Being together was our client's requirement.So, we integrated those ancient concepts into our design BY defining a central courtyard, placing the staircase within it, and opening terraces to it. Like the Sibe,the courtyard and stairs are a place for interaction.
