Interior architecture is the design of a building or shelter from inside out, or the design of a new interior for a type of home that can be fixed. It can refer to the initial design and plan used for a building's interior, to that interior's later redesign made to accommodate a changed purpose, or to the significant revision of an original design for the

practices, whereby resources are conserved by "recycling" a structure through adaptive redesign.
Generally referred to as the spatial art of environmental design, interior architecture also refers to the process by which the interiors of buildings are designed to address all aspects of the human use of their structural spaces. Put simply, interior architecture is the design of an interior in architectural terms.
Interior architecture may refer to:

* a style or method of design and construction for a building's interiors and related physical features.
* the practice engaging work on already existing interior environments, where adaptive re-use and a knowledge of architectural strategies are necessary for re-designing existing space.
Evolution
Adaptive reuse

Although the original spatial hierarchy of a building is always established by its first architect, subsequent iterations of the interior may not be, and for obvious reasons, older structures are often modified by designers of a different generation according to society’s changing needs as our cities evolve. This process often re-semanticizes the building as a consequence, and is predicated on the notion that buildings can never really be complete and unalterable.
An altered building may look the same on the exterior, but its interior may be completely different spatially. The interior architect must therefore be sensitive not only to the place of the building in its physical and socio-political context, but to the temporal requirements of changing owners and users. In this sense, if the building has “good bones” the original architectural idea is therefore the first iteration of an internal spatial hierarchy for that structure, after which others are bound to follow

and character of the city is generally held to be more desirable than the possibility of a new building on the same site, although clearly economic forces apply. It is also possible to speculate that there might well be further new interiors for these structures in future years, but for each alteration the technical and technological expertise of the era will determine the extent to which the building is modified in its
building life cycle.
Certain structure's interiors remain unaltered over time due to

, unchanged use, or financial limitations. Nevertheless, most buildings have only three possible long-range internal futures: First, designated significantly important to maintain visually unchanged, only accommodating unseen modern utilities, access, and structural stabilization, and restoration needs. Second, demolished to make way for a new building on the same site, or abandoned, becoming ruins. Finally, redesigned and altered to accommodate new uses.
There are many different degrees of alteration – a minor one to enable the building to conform to new legal codes is likely to prolong the first (or indeed later) iteration of interior space, but a major alteration, such as the retention of only the
facade, is to all intents and purposes a new building. All possibilities within and between the two extremes are the domain of the interior architect.
If the practice of architecture is concerned with the art and science of new building, then the practice of Interior architecture is concerned with the alteration of existing buildings for new uses.
Sustainability
A critical part in the evolution of interior architecture and design is the central theme of
sustainability
Sustainability is a social goal for people to co-exist on Earth over a long period of time. Definitions of this term are disputed and have varied with literature, context, and time. Sustainability usually has three dimensions (or pillars): env ...
and consciously thinking of the environment and the materials being sourced- energy use, site selection, water usage, and material selection (Leigh Bacon). This sub-category of Interior Architecture focuses on finding creative and holistic ways of building new or
retro fitting existing structures that have little to no impact on the environment. The eco-friendly movement became an important issue around the 1970s when the major energy crisis struck, making individuals aware of their contributions and what can be done to help lighten the impacts (BStone). Sustainability in Interior Architecture has really taken off in the last few decades with the help and advancements of technology, discovering new materials and efficient concepts that still lend the aesthetically pleasing aspect of a design. In past years, when it came to eco-design it had a stale and lack of luxury, elegance, and overall design; which inevitably received the reputation of being a "hippies" style or way of living. This is far from the case today with the overall known importance of being environmentally responsible, having an abundant amount of material options, and wanting to withhold an aesthetic design.

is now a preferred and desired way of thinking and building that has and will be an ever-expanding and growing field.
Some people confuse interior architecture with interior design. Because interior renovation will touch the change of the internal structure of the house, ceiling construction, circuit configuration and partition walls, etc., such work related to the structure of the house, of course, also includes renovation of wallpaper posting, furniture settings, lighting, etc. It is worth noting The thing is, the decoration construction team must be approved by the established interior design company to guarantee.
Earnings
Statistics
In the United States, median annual wages of wage-and-salary architects were $70,320 in May 2008. The middle 50 percent earned between $53,480 and $91,870. The lowest 10 percent earned less than $41,320, and the highest 10 percent earned more than $119,220. Those just starting their internships can expect to earn considerably less.
Earnings of partners in established architectural firms may fluctuate because of changing business conditions. Some architects may have difficulty establishing their own practices and may go through a period when their expenses are greater than their income, requiring substantial financial resources.
Many firms pay tuition and fees toward continuing education requirements for their employees.
Education
Purpose
Education in interior architecture should include the study of historic architectural and interior decoration styles, building codes and safety, preserving and restoring old buildings, drawing plans of original designs, and building physical and virtual (computer-based) models. The field of interior architecture has a lot in common with interior design and decorating; however, it typically focuses on architecture and construction. Students of both fields learn to design comfortable, safe, and useful indoor spaces, from downtown penthouses to high school classrooms. A student of interior architecture will learn about much more than artistic concerns, such as choosing which style of furnishings works well in an open, loft-like apartment. Study will also include information on technical issues, such as seismic retrofitting (making old buildings safe from earthquakes).
Degree programs
Interior architecture stands at the intersection of architecture, design of the built environment, and conservation. Interior architecture programs address the design issues intrinsic to the re-use and transformation of existing structures through both an innovative and progressive approach.
The National Center for Education Statistics states that the definition of a degree program in interior architecture is: "A program that prepares individuals to apply architectural principles in the design of structural interiors for living, recreational, and

In addition to earning a degree in interior architecture, general licensure is required to work within the United States and some states have further licensing requirements. In many European countries and in Australia the use of the title "Interior Architect" is legally regulated. This means that a practicing professional cannot use the title of "Interior Architect" unless they complete the requirements for becoming a registered or licensed architect as well as completing a degree program.

Difference between an Interior Architect and Designer
Interior architects focus on building interiors, space planning, and exteriors. This included planning a space to be functional, accessible, and aesthetically pleasing. They notate the appearance of the building, safety, and usability of the users in the building. They will create site plans, building sections, energy calculations, exterior elevations, window & door schedules, and more.
An Interior designer focuses more on the furnishings that will be included in the space and the decorations associated with the interior. This is not to be confused with an
Interior decorator who purely focuses on design aesthetics and furnishings. They will select furniture, soft goods, drapery & window coverings, and wall coverings. They focus on the harmony felt in a space which relates to room placement, size, and layout.
Both professions have a middle gray area where both perform the same tasks. This includes the selection of interior finishes, creating drawings of interior elevations/details, and space planning around furniture placement.
Associations of Interior Architects and Designers
Experienced and trained Interior architecture and Interior design professionals are often represented by national, European or international professional organizations and
federations. These associations represent and advocate on behalf of its members to ensure that the expertise of the built environment professionals is recognized and respected.
European Council of Interior Architects (ECIA) is the representative body for the European professional organisations in Interior Architecture and Design. Founded in 1992, ECIA currently represents 22 members-national organisations, with approximately 18000 professionals Interior Architects/Designers.

contemporary. Most attraction to these styles would be to those born during this period, but since the recent reinvention of these design styles, it has become more widespread in current architecture and interior design.
As of current, modern architecture is taking a turn toward a more abstract-looking design, but this showcases how it was before this progression. These design styles have influenced modern architects and designers by providing alternatives to modern design's common problem of feeling cold, too simple, and uninviting. Introducing more textures,
warmer colors, and curvilinear lines have transformed modern architecture into a more usable style. It also influences incorporating sustainable materials into design in the 21st century. We have reinvented the style with sustainable materials and finishes without altering the original basis.
