Interior Architecture is the design of a space which has been created by structural boundaries and the human interaction within these boundaries. It can also be the initial design and plan for use, then later redesign to accommodate a changed purpose, or a significantly revised design for adaptive reuse of the building shell. The latter is often part of sustainable architecture practices, conserving resources through "recycling" a structure by adaptive redesign. Generally referred to as the spatial art of environmental design, form and practice, interior architecture is the process through which the interiors of buildings are designed, concerned with all aspects of the human uses of structural spaces. Put simply, Interior Architecture is the design of an interior in architectural terms.Interior Architecture may refer to:The art and science of designing and erecting building interiors as a licensed architect and related physical features.The practice of an interior architect, where architecture means to offer or render professional services in connection with the design and construction of a building's interior that has as its principal purpose human occupancy or use.A general term to describe building interiors and related physical features.A style or method of design and construction of building interiors and related physical features.^ "Frank Lloyd Wright: His Life and His Architecture," Twombly, Robert C., John Wiley and Sons, Inc., 1979, p. 384.^ "Interior Architecture".
