Abstract: A modular playhouse comprising a plurality of sections derived from two related modular units. The first modular unit is a right angle triangle having its hypotenuse equal to twice its base. A set of two-dimensional sections based on the triangular module having linear dimensions each of which corresponds either to the base, the hypotenuse or the height of said triangle. The second module is a rectangle having a width equal to the triangle base and a length equal to the triangle hypotenuse. A set of two-dimensional sections based on the rectangular module have linear dimensions corresponding to the length and width of the rectangular module. The box in which the sections are packaged is adapted to form a table-like structure for supporting and securing said sections, the size and proportions of said table-like structure also being derived from the two related modular units. Said sections are connected to each other and to the table-like structure by bendable or flexible strips.
