The invention relates to a modular design of frontage of real estate, the aforementioned 閠antform閑 construction mainly of frameworks (2) generally out of wooden, stiffeners (3) arising in form dismounting and/or of cross-pieces and bodies (4) of connection between framework (2) and stiffener (3). This construction is characterized in that two frameworks (2), in a juxtaposed state, delimit between them unespace (5) of reception of a stiffener (3), frameworks (2) and stiffener (3) being joined together one with the other by unorgane (4) of connection crossing commun run.
