When it comes to design our homes, which have a limited space, we are looking for all available means to successfully "furnish" the house, despite its limited space, so it is imperative to reach the smartest solutions for furnishing this house. These solutions would be conducive to getting the most out of small spaces, and it is preferable to use furniture pieces that are convertible from one function to another so that the furniture pieces perform more than one function, while taking a small space in the house. The multi-use furniture is the result of effective and innovative solutions in the field of interior design to the problem of small living space in light of the population growth and the financial crisis facing the world and the tendency of countries to horizontal expansion which is the acquisition of pieces of furniture that can be transformed from one shape to another or from one job to another in line with the modern style using the art of origami in order to achieve several objectives, including solving the problem of small spaces and making good use of them in addition to adding an aesthetic touch to the interior space, and this is done using the art of origami. Origami is an ancient Japanese art that means forming paper to make three-dimensional models using techniques of folding and carving and combining these techniques with various paper shapes to create composite designs. From the standpoint of emphasizing the role of the interior design in finding solutions for limited spaces, the idea of research came to conclude ideas for multi-use and convertible designs that serve narrow interior spaces using the art of origami.
