A technique is provided for transmitting a roof structure for constructing a three-dimensional representation of a building, via a communication network. The technique is based on the transmission of an ordered list of at least two roof models, each including at least: one type of roof; one maximum height parameter of the roof. During construction of the three-dimensional representation of a building, the maximum height parameter of a roof of the list determines a base of the roof in accordance with the list, so that the roof structure corresponds to the ordered superimposition of the roods of the list.
