The Lebanese architect Paul Kaloustian studied at Harvard and then worked for Herzog and de Meuron. This architect has recently designed his own office and the Chammas chalet in Libanon. The new location of the office is in a former factory, in the capital of Libanon, in Beirut. The design intention is based on creating an airy and at the same time abstract space. The essence of the interior is the white colour where the means for discrimination of lines and shapes is mostly light, whether natural or artificial in the form of various lights. It could seem that such space gives impression of sterility and coldness but that is not the case. Plants added to the interior wonderfully refresh the atmosphere. The Chammas chalet is designed in a similar way. Probably its most interesting feature is the zigzag roof designed to give the space a sense of tension and dynamism.
