Constant changes occur to the family requirements of housing with the flowing of time, and these changes
are due to the number of its members, their needs , the standard of living the economic conditions , or as a
result of increasing technical dev
elopments. This implies facing house requirements and applying changes
in the number of the house rooms, or the functions of these rooms. So the family either tends to change its
house to fit its needs, and that exhausts it socially and financially. They made adapt their house with the
family constant needs, and here comes the importance of achieving flexibility as the best economic solution
that reduces the value of the house, of it, by providing the efficiency of the best use of the whole spaces.
In addition, the role of flexibility is to respond to the social stability of families by the best use of the whole
time age of their houses.
This research handles the concept of design flexibility as one of the most economic housing standards in
the thesis of the most important architects , and goes through steps of applying it in the house functionally
and structurally in the designing phase by effective interaction between the designer and the user side by
side.
The research works based on an economic study on sugar beet crop in Syria
during the period (1985 2003), and its prospectives taking into account the
cultivated area, yield and total production in order to know the extent of
cultivation developmen
t and the factors influencing this crop.
Results showed that the area under sugar beet was unstable, which
negatively reflected on the yield and production during the studied period.
However, these changes were not statistically important for the cultivated
area (non-significant regression), while the regression was significant for the
yield and production.
