One of Le Corbusier’s major aspects of architecture is regulating lines. It is the spirit of the construct. Corbusier says that the idea of using regulating lines has been constant even since the primitive man. It does not matter if the construct is an ancient temple or a house. It makes use of these lines which will govern decisions about the elements of the composition. Also the use of regulating lines creates a satisfaction in both artistic and mathematical thoughts. Because the regulating lines cannot be brought to life without measurements and calculations. Through these calculations we conclude in simple geometric forms which are easy to grasp by the human eye. So it is completely agreeable that geometry is the language of men. As expected of Corbu, he is not pleased with the works of architects of his time and wants them to make use of these simple geometries instead of searching complexity in a poetic manner.
Besides the Notre Dame’s regulating lines as seen above, regulating lines have been used in works of The Greek and The Egyptian too, to make their task easier. Even throughout my process of learning how to draw using the orthographic projection method, I saw that these lines helped me a lot while creating forms.
By using regulating lines the architect increases the quality of the rhythm inside the composition. All in all, regulating lines are one of the fundamental rules to be followed while creating as they make a generic plan they also lead the secondary elements to adapt themselves to the design according to the same rule.
P.S: (If I’m not mistaken about the meaning of the words in this context) I find it interesting and witty how Corbusier links architectural matters with non-related things in a jokingly way. Like in this reading when he says “The primordial physical laws are simple and few in number. The moral laws are simple and few in number.”
