This system involves masonry brickwork supported on closely spaced rafters. Thin bricks (or bricks laid on edge) are held together by lime mortar on timber rafters. The top layer of bricks is laid flat over the bottom layer, and is then topped by a layer of lime surkhi (lime concrete). The rafters usually rest on the load-bearing walls. This flat terrace method of roofing has been used in the gopura to form intermediate floors at the five stepped levels. As many as six layers of brick form part of the Madras terraces here.
