Missing Corner or Protusion
MISSING CORNER OR PROTUSION?
FINDING THE CENTER-OF-GRAVITY
In my opinion, as the terrace area is large, and considering the "center-of'gravity" if we exclude this "terrace" portion, I would personally consider the "extra area of Living Room (in RED) as a protusion instead.
Sometimes, rudimentary action can be:
- place a copy of the layout plan and paste it onto a cardboard.
- cut out the outline (exlude the terrace only).
- balance the cardboard on a pin. As the floor area of the protusion is small, most likely your "CENTER of GRAVITY" would fall close to the centrepoint of the rectangle as shown by the crossing of the two diagonal lines.
