96 PRACTICAL BUILDING. [LECT. II.
The design of an c ice is commonly laid down
on three several draughts.
First, a Plat?, which exhibits the extent, divisions,
and distribution of the ground, into the various apart-
ments, and other conveniencies. Plans are olten
made for the several stories: as their distribution
may differ occasionally.
A second drawing represents externally the sto-
ries, their heights, and the general appearance of the
whole building: this is termed an Llevatioft.
The third drawing is the Section, and shews the
internal parts of the fabric; the front wall being
supposed absent.
By means of the Plan, the Elevation and the Sec-
tion, an estimate may be made of the expence, time,
&c. a building may require, according to its mea-,
surement. And the most accurate estimates are
necessary in this art, because some things always
occur that could not be foreseen; but for which in
good estimates allowance is regularly made.
