It is a duplex housing concept, in which we have modified the usual type of these houses, that leaves a small front terrace and a backyard. In this house we have removed the backyard giving the entire outer space to the front terrace, allowing generate an exterior space deprived of greater dimensions. In this case as the corner plot is located, giving that terrace to two streets.
