A concept is an idea, a theory or notion, but in architecture we could also describe a concept as ‘an approach’ to the design.Architectural concepts are the designers way of responding to the design situation presented to them. They are a means of translating the non-physical design problem into the physical building product. Every project will have critical issues, central themes or problem essences, and the general issues of designing a building can be approached in a number of ways.

And there’s 5 concepts:

-Form:

It is the external configuration of things ,way of being distributed the matter of a body .arrangement of a part of a whole according to certain relationship.

-Place:

The place it’s another of architecture and it’s very important because from the place we can guess what is the design that it should be maintained A sense of place is defined as the bond between place and humans, which can be obtained from a combination of physical settings, activities, and meaning.

-Materiality and structure:

Materiality in architecture is a concept or the applied use of various materials or substances in the medium of building. This concept was previously regarded as a secondary consideration in architecture but recently emerged as an important element due to advances in digital fabrication and digital science.

The concept plays an important role in architectural practice, which is actualized through the body and senses of an architect interacting with his physical work environment. It defines critical aspects concerning the governance and engagement of an architectural system.

-Function:

The concept of function had always existed ,This concept don’t produce problems because we have just to ask ourselves what we must build to satisfy a function.Buildings have a wide range of different functions, for example, a house is to be lived in, an office serves as a place of work for business activities, a shopping centre is for consumers to access retail outlets, a school is for pupils and teachers to undertake education, and so on.

-Space:

Space encompasses the volume of a structure, the parts of a building we move through and experience. But space can only be created through the use of form. Form is the mass, or grouping of materials, used to give a building its shape.ç
