Architects at the nineteenth century began to quote from the past architecture models
and use them until they reached a modern architecture that has become a way to the
face conditions and solve recent problems, At the beginning of the twentieth ce
ntury,
architects do no longer quote, but rather they contribute to shape the environment, so
they dealt with the definition of functional theory, that accompanied the emergence of
modern architecture, coupled with the name of the French architect Le Corbusier. Early
twenties appeared clearly in the design of interior spaces of official buildings in the city
of Damascus, and highlighted the similarities and differences among them. Therefore we
study the influence of this theory on the Architectural spaces of the total volume of the
building, considered a significant impact in highlighting the needs of these buildings in
the rehabilitation process, and we specified the requirements that meet the comfort and
utility to take advantage of the characteristics of the architectural features of different
spaces, in addition we study the functional relations for these buildings, then select the
new architectural elements that have emerged and study the possibility of its optimal
position. All this work was within the framework of contributing to the functional design
of internal spaces for the official buildings to keep pace with modern requirements and
regulations of modern management for such buildings.
