Recently, with the dominance of modernity, the rules of art and 
design have changed dramatically. This development was built 
on the accumulation of many scientific and philosophical 
theories to keep pace with technological progress. The College 
of Design is considered the most influential school in the 
twentieth century, and with the progress and development of 
artistic movements, modern art reached the height of mental 
thought. Through it, it is possible to formulate visual creations 
based on intellectual and philosophical perceptions that are 
translated linguistically into a dialogue that arises between the 
user and the surrounding elements of the design of the interior 
space. Hence, the Gestalt theory was based on the mechanism of 
operating the perceptual process of the individual, in order to 
transcend what is sensual to become fully aware, She explained 
that perception is a regulatory process for the inputs of sensory 
stimuli arising as a result of the interaction between the different 
senses and their interpretation to perceive the meaning, and by 
combining the Perception of the psychological process, 
sensation and the physiological process A number of principles 
for understanding the perceptual field have been reached, known 
as Wertheimer's principles.
This paper presents the identification of design strategies 
according to the principles and laws of Gestalt theory and its 
impact on the design art , perceptual, sensory and aesthetic 
process on the functional design of the interior space, and 
provides the possibility for the designer to address his design 
vocabulary from theoretical characteristics and reformulate them 
using modern materials and techniques, to form aesthetic 
arrangements that reflect the Gestalt perceptual concept and its 
impact On the design process of the concepts of interior 
architecture, leading to its crystallization on the aspects of the 
artwork and inputs sensory that enhance the design foundations 
and enrich the philosophical value of the space.
