"Reinforced concrete provided me with incredible resources," he wrote later, "and variety, and a passionate plasticity in which by themselves my structures will be rhythm of a palace, and a Pompieen tranquility." This led him to his plan for the Dom-Ino House (1914–15). This model proposed an open floor plan consisting of three concrete slabs supported by six thin reinforced concrete columns, with a stairway providing access to each level on one side of the floor plan. The system was originally designed to provide large numbers of temporary residences after World War I, producing only slabs, columns and stairways, and residents could build exterior walls with the materials around the site. He described it in his patent application as "a juxtiposable system of construction according to an infinite number of combinations of plans. This would permit, he wrote, "the construction of the dividing walls at any point on the façade or the interior."
