Solitude Space in Urban

Urbanization in Vietnam is inevitable, but rapid urbanization with dense traffic and construction is the main factor that leads to the disappearance of silences, which has the ability to repair and enrich the mind. Nicola Tesla said, “Be alone, that is when ideas are born” (Goodread in Retrieved from A quote by Nicola Tesla: https://​www.​goodreads.​com/​quotes/​962527-be-alone-that-is-the-secret-of-invention-be-alone [2]). Indeed, solitude is a choice and a demand for space where people can contemplate and explore themselves, which leads to enlightenment. Especially in the epoch when artificial intelligence is extremely popular, personal thought is very important, not only to develop but also to control things that are unexpected. In the field of architecture, architects have the ability to provide suitable spatial solutions for solitude space, which is the proposal for urban to create an environment for personal experience and reflection, which can be applied from micro to macro, and change the face of urban in future. Individuality and community are considered two basic spatial properties, always existing and arranged according to certain principles, thereby shaping urban spaces. Therefore, the creation of solitude spaces does not exclude public space or focus only on personal space; instead, it is a problem of harmony based on the nature of users in the urban area. From this, it can be seen that the basic principle for the formation of solitude spaces is the creation of simultaneous spaces in which individuality and community are both separated and connected at the same time. The main method of the above principle is to separate all the components of the two types of space (Individuality and community), then combine them so that the simultaneity is strongest. There are four keys of strong simultaneity.
