What are the constraints between Architecture and Interior Architecture?

 architecture and interior architecture for  me are like twins they can't leave without each other but one is going up before the other when architecture give u the general idea about this twins and interior show u their own word with all privacy,creativity with all small and small details 

The constraints between architecture and interiors is the scale of the design , architects usually design buildings and leave the fine detail of the internal environment to the interior designers. So I feel that the interior designer is much closer to the end user and you get to design more directly for human usage. Architects tend to work in the bigger picture and deal with the technical aspects including keeping the elements out and working to stringent building regulations. 

In brief: The architecture is the real application of Art on science including all the aspects to achieve higher levels of humanity dimensions (physiological affects of designs & urban designs on human communications in societies) or ( The Art of controlling users).

The Architecture in its wide meaning includes:

1- Planning:(Urban planning, Regional Planning, City planning),

2- Landscaping (Land use).

3- Construction designs ( Buildings) includes (structural supports systems distribution design) for wide spans like stadiums.

-as a coming next level  for no. (3) here comes the Interior Architecture role its the same definition but on small scale.

*here are some not all of the constraints :

1- It has to respect the borders & boundaries which  has been done by the Architecture.

2- It has to follow & continue the philosophical design concepts of the Architectural style surrounded by, in other meaning to be an extension for the general design.

3- It has to respect the material used in the surrounded Architectural environment (Local area) and colors as well.

4- It has to respect the structural system already done by Architectural & structural Engineers.

5- It has to solve and modify any issues found in shapes done Architectural ( completes the Architecture).

 & more other points but in generally the Interior Architecture should take more care of the physiological dimension in design (which is the last point to notice while design process in reality as it concentrates more about the cost) but it can be done in both dimensions of cost & beautiful simple design.

The constraints being the design ratio , Architects ensure the building design with technical ability and working to codes,practices and building rules and  the interior details of fitout are left for the interior designers. Interior designers are much closer to the  user and architects much closer to the client.

Archecture is external design of building , interior is the finishing design for a residential or business or small thing 

its a matter of level of details and functions, for the principles it always the same

Proper coordination between all the relevant ID and Architectural trades with MEP should be able to allow smooth execution of any fit-out project.

Architecture and Interior is Complimentary. one is developed proportional to the other.For example the designs of zaha hadid had her own interpretation on exterior as well as interior. interior Architecture have some frameworks like its architectural elements Shapes like so. so it is dependent to architecture.

Time frame to work.

Space constraints,

Form challenges.

Architecture: is the bigger picture of the design, it is a whole mass of the building design, exterior facades, pillars, walls, exits and entrances, lighting slots, and supplements, the main division of the distribution of the internal spaces as places of rooms and bathrooms and kitchens, as well as its relationship with outdoor spaces and the relationship the general location, known as the distribution of powers Foreign construction and raw materials, and the building is safe for use.

Interior: is the most in-depth and detailed image, he is uncle design all of the above details of finishes and colors, texture and the general atmosphere, interior and exterior lighting, furniture and internal distribution to divide more detail phrase .. may not be able to act to remove the walls or deep or radical change in the cluster

Interior Architecture: It may be a new term, but combining the two .. he is able to build the idea of ​​the home of the foreign mass down to choose the door handles .. can design the building completely, but it also needs as the architect needs a structural engineer
