Le Corbusier's Towards a New Architecture suggests architects all over the world in the 20th century to take actions His architecture is broken down into three parts Mass Surface and Plan which is the main elements He claims that mass is the simple creative forms of geometry that engineers try to figure out but instead architects have abstained from using it The surface is the face of mass where architects are afraid to use whereas the engineers used it to reflect the shape of the building Lastly the plan is the heart of the building as it does not only generate the elevations but ensure the spatial experiences itself H This quotation makes it clear about Le Corbusier think about the plan This part started by defining the title Le Corbusier refers to this quote that the engineer's aesthetic has increased compared to the position of architecture it has firmed What he meant is that architecture has been lost through the past as the engineers started to adopt new technologies and build purposely functional structures
