Bay or Bow Window
A bay or bow window is a projection on the side(s) of a house which may or may not be
considered a livable area. If the bay window(s) include useable floor space, it must be measured,
drawn on the sketch at its actual location and properly labeled. Bay windows are most often
angled and are drawn to scale on the sketch as they exist, plus a few extra measures as described
below to allow for accurate area calculations.
Only needed if different from other side
How to measure and sketch a bay window:
1.) Classify the bay window according its appropriate story height.
2.) Check for basement area under the bay window upon listing.
3.) Bay windows are only picked up when they include floor space.
In the case of a Bow window, the same floor area requirements exist as with the bay window.
However, measuring is a bit different. We need to know the depth of the window (5') and the
length (24') to be able to sketch and calculate the area. In this case, the length from the point
where the bow begins to where it ends is 24 feet. The altitude of the arc created by the bow, or
the depth of the window, is 5 feet.
Angles
Angles are a common type of measure that we come across in the field and it is crucial when
measuring an angle to have enough written measurements on the sketch. The square footage on
an angle cannot be computed if the appropriate measurements are not placed on the drawing.
Create a right triangle on the ground where the hypotenuse is the building wall that is at an angle
from the main structure, then draw that triangle in your sketch giving all the measurements.
The two dashed lines form a 90°
angle or right triangle with the
building wall being the hypotenuse.
Record all the dimensions
accurately. With this information,
the ATU/GAR addition and the FFF
area can be drawn and calculated
accurately.
