Design
Design is the creation of a plan or convention for the construction of an object, system or measurable human interaction (as in architectural blueprints, engineering drawings, business processes, circuit diagrams, and sewing patterns). Design has different connotations in different fields (see design disciplines below). In some cases, the direct construction of an object (as in pottery, engineering, management, coding, and graphic design) is also considered to use design thinking.
Interior Design
Interior design is the art and science of enhancing the interior of a building to achieve a healthier and more aesthetically pleasing environment for the people using the space. An interior designer is someone who plans, researches, coordinates, and manages such projects. Interior design is a multifaceted profession that includes conceptual development, space planning, site inspections, programming, research, communicating with the stakeholders of a project, construction management, and execution of the design.
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.
Virtual
An item may sometimes be described as being a virtual item when it is a representation or non-tangible abstraction of the physical object, or is a functional emulation or simulation of it.
Design
Disguise and complication are hindrances, both to good construction and good design, and as complication and disguise are expensive and wasteful... the interests of good art and true economy run on parallel lines.
Ernest Flagg, Small Houses: Their Economic Design and Construction (1922)
Design
Design is redesign.
Jan Michl (2002), in "On seeing design as redesign" (Scandinavian Journal of Design History 12, 2002: 7-23.)
Interior
But it is not only of space in the Church which we ought to be jealous, but also of the interior of the house of God in us, so that it might not become a house of merchandise, or a den of robbers.
Ambrose, Commentary on John 2:16, Exposition of the Psalms of David 118 (PL 15 1457B)
