Creating a Floor

• All floors will look like the following unless
  using a slab foundation
• When using a slab foundation the slab is the floor

3
Starting a Floor

• The floor starts with a sill plate
• The sill plate makes direct contact with the
  foundation
• The house literally sits on the foundation

4
Floor Joists

• Floor joists run perpendicular and parallel to
  the sill plate and flooring frame
• Floor Joists are to be spaced 24 oc

5
Posts

• Posts are installed in the foundation to hold up
  the beam
• The beam of the floor is a board (three pieces
  thick) that runs down the center of the house
• The beam supports the floor joists

6
Connecting the Joists to the Beam

• Floor joists meet in the center above the beam
• Most floors are better organized than the
  pictures to the right

Framing a Fire Place

• This cantilevered section represents where a
  fireplace will eventually be installed

Laying the Subfloor

• Once the floor is framed it is covered with
  either ½ plywood or 5/8 OSB (oriented strand
  board)
• The plywood or OSB is called the subfloor
