The Majunga-building designed by the architect Jean-Paul Viguier, consists of three contiguous flats expanding each in its own way, but designed to form a whole. The facades are cut to insert gardens with plants, entering the thermal control system and break the monotony of levels. The desire for an asymmetric design with regard to the central axis, led us to design three sides of different thicknesses which are giving full expression in the resulting volume through a striving for autonomy of the form. Thus three bracketed plates are used, each expanding in its own way but designed to form a whole: diversity and uniqueness. The resulting tower is a new-style building with a singularity of which is clearly stated without having to rise beyond 180 meters. This principle enables a response to the specific context of the tower at its base by connecting it to the esplanade and the new gardens below. It also makes it possible to manage the tower's contact with the sky by using an original top which underlines the breaking down of the volume into three parts.
