House Build

Let’s create a floor plan in 3D to help visualize how it works

SCALE

• Architectural drafters use architect’s, engineer’s, and combination scales.

3

Architect’s Scale

• Divided into 3/32", 3/16", 1/8", 1/4", 1/2", 3/8", 3/4", 1", 1-1/2", and 3" to the foot.

• One edge divided into 16 parts to the inch.• Divisions based on 12 units to the foot.• Used for most work.

4

Size Compared to Scale

• “Size” and “scale” need clarification.• “Half size” means the drawing is one half as

large as the object.• Scale: 1/2" = 1'-0" means the drawing is

1/2 scale.• 1/2 scale means 1/2" on the drawing = 1'-0"

on the object.• Residential plans are generally 1/4" = 1'-0"

scale.

5

Reading the Scale

• The 1/8" = 1'-0" and 1/4"=1'-0" scales are printed on the upper edge of this architect’s scale.

6

Reading the Scale

• The proper method of measuring 16'-4" using the 1/4" = 1'-0" scale.

Time for Math

• If a room is 12’ x 12’ (master bedroom)…• What would it be if it was drawn at ½ size?• What would it be if it was drawn at ¼ size?

Full 1/2 1/4

Scale Applied

• If a room is 12’ x 12’ (master bedroom)…• If our scale is ½” = 1’-0”….every ½” on your

paper would be 1’ of the real object…so the room you would draw would be how big?

12”

12”

6”

6”

It’s Got to Fit on the Paper

• If a room is 12’ x 12’ (master bedroom)…• If our scale is ¼” = 1’-0”…the room is 3x3• If our scale is 1/8” = 1’-0”…the room is 1.5x1.5

• If the house is 40x60…what is it at ¼ scale?

OK…Assignment Time

• Design a ranch style home (one story)• Include the following:– Master bedroom and bath with closet– 2 guest bedrooms with closets– Guest bathroom– Living– Kitchen– Dining or office– 2 car garage– Laundry / pantry / ½ bath / linen / coat closet
