    Free plan


    • The free plan, as it relates to architecture refers to an open plan with non load-bearing walls dividing interior space. In this structural system, the building structure is separate of the interior partitions. This is made possible by replacing interior load-bearing walls with moving the structure of the building to the exterior, or by having columns that are free from space dividing partitions.

      Free plan, in the architecture world, refers to the ability to have a floor plan with non-load bearing walls and floors by creating a structural system that holds the weight of the building by ways of an interior skeleton of load bearing columns. The building system carries only its columns, or skeleton, and each corresponding ceiling. Free plan allows for the ability to create buildings without being limited by the placement of walls for structural support, and enables an architect to have the freedom to design the outside and inside façade without compromise.

      Le Corbusier became the pioneer of free plan during the 1914 through 1930’s with his “Five Points of New Architecture” and his adoption of the Dom-ino System. This heavily influenced the importance of free plan and its role in the “modern era” of architecture.

      The Dom-ino system refers to the structural system that allows a free floor and wall plan, due to the load bearing columns within the skeleton of the structure. Originally conceived as a two story building, six vertical columns held the two concrete, steel reinforced floors in space. This allowed for exterior walls that accommodate to the aesthetic and compositional features of the building. This also created a free floor plan, moving from the previous ideology of load bearing walls. This new technology allowed for long strips of windows that could wrap corners and stretch greater lengths, something that was never seen before in architecture. This building system became a staple for high production buildings because of its cheap and fast production rate. Ways could be fashioned in any way, restrained only by technological advancements of the time.

      Corbusier adopted what he considered to be the most important five architectural points in his architecture: pilotis, free plan, horizontal windows, a free façade and roof top gardens. The ideas all surface around the main point of free plan and the use of the Dom-ino system. The piloti system carries all the weight allowing for a free plan as well as a free façade. The free exterior façade allowed for vast openings and horizontal strips of windows creating aesthetic value. All of the five points work together, being based off the premises of the Dom-ino system, varied to a degree for aesthetic purposes.
