Draw a sketch outlining the layout of the room including details like fireplaces, windows, columns, etc.
Start with overall width and length of the room.
After getting the overall measurements begin measuring each individual wall in greater detail. Starting from one corner and working your way all the way across to the next, giving specific information about any windows, doors, built-ins, radiator, electrical outlets, etc.
Include additional measurements such as, window height, door height, fireplace (hearth length and width), and height of ceiling from lowest point to the floor.
Notate all ceiling fixtures and approximately mark their current location on your drawing.
Please provide for any walls with important architectural elements.
Draw a sketch of the overall shape of the wall including windows, doors, existing lighting (sconces), fireplace, radiator, electrical, built-ins, etc. Measure in detail the location of each individual item for accurate placement on the wall.
Include overall ceiling height and molding detail information if necessary.
