Building an Attic Stairway

Choose a location on the ceiling where a ladder can be lowered -- some place that is relatively inconspicuous, but that is open enough to allow easy access. Using the stud detector, mark out a spot where ceiling beams meet, ideally in a large, rectangular shape. Cut along these lines using the saw, exposing the attic space.

Build a rectangular frame that will sit inside the ceiling beams and add strength to the attic stairs. Nail it into the ceiling beams. Consider using metal mounting brackets at the corners of this frame to add additional strength.

Measure the opening to the attic and cut a piece of wood to serve as the door. Sand and paint this piece to match the ceiling. Mount it to one side using hinges; mount it in the way you'll want the stairs to come down.

Take two long beams and create a ladder that is long enough to get from the floor to the attic. Use beams that are sturdy, but slender enough to fit through the opening when folded.

Build the ladder by Nail steps in between the two beams to build the latter. Ensure that you do this carefully and at a comfortable distance apart for climbing.

Cut the ladder into thirds with the saw. Reattach the three pieces using hinges. Mount one end of the ladder to the top of the opening, near where the door is mounted. Test that the ladder folds properly; make adjustments like cutting the ladder a bit shorter or moving mounting points, if necessary.

Mount springs on the left and right side of the ladder. Attach one end of the spring to the ladder, and one end to the far opening of the attic entrance. These springs need to be tense enough to take some of the weight out of lowering the ladder. This option is less sophisticated than a tensioned pulley system; it doesn't work as well, but is easier to build and is functional.

Fold the ladder and close the door. Install latches on either side of the far opening, to hold the door shut.
