Architecture is the practice of designing and planning the construction of buildings and other structures. This quote means that architects need to think carefully about how to arrange spaces in a way that makes them efficient and maximizes their use, while also making sure that any spaces that don’t need to be used are not included in the design. Architects need to be creative in their designs so that space can be used in a way that is aesthetically pleasing and meets the needs of the people or purpose of the building.
