The Namaz Khaneh, located in Tehran, Iran is a very simple but beautiful space. An afterthought as part of the designing of the entrance to the Carpet Museum by Kamran Diba. This open air prayer space, not much bigger than nine metres squared, has an outer wall orientated to the street grid, whilst an internal wall is orientated towards the direction of prayer. This basic maneuver creates a void space between the noisy surrounding areas and the internal space for contemplation and prayer. The two walls are also connected by a vertical slit in both walls creating a view to a sculpture representing the standard Hand of Hazrat Abbas, which also acts a the Mihrab for the space. This separation of walls is also interesting if it was used in say the ventilation strategy for an energy efficient building.
