A modular designing strategy is proposed employing the periodic tessellations used by Dutch artist M.C. Escher as source of inspiration. It consists in modifying a bidimensional shape to fit geometrically programmatic requirements of an architectural project operating as an insertion support of 3D forms. The procedures followed by the artist are analysed, specially those using figures that tessellate the plane periodically, applying different symmetry rules. Once the rules to generate shapes of tiles are known, we work within area and perimeter to satisfy modularity requirements and to convert the tiling as a geometric precise support for the insertion of architectural objects that follow predetermined dimensional patterns. An example of grouping repeatable habitation units is presented.
