Log stairs can be a simple, yet eye-catching addition to any log home. While there are many different types of staircase styles you can choose from, the most common design is an open tread staircase made with halved logs.

Watch the video to see Northern Log Supply Owner Peter Green demonstrate how to build a half-log stairs or follow the directions below.

1. Measure the Space

Prior to building your staircase, you’ll need to measure the space your staircase will occupy (you can use this form to help). You’ll need to measure the:

  • Rise (Height between the lower floor and the next floor)
  • Run (How far your staircase can come away from the wall)
  • Width (How wide your staircase can be)

2. Gather the Materials

To complete your staircase, you’ll need the following materials:

  • A pair of stringers
  • Treads
  • Lag bolts

The number of treads you have will depend on the rise and run of your space.

The tools you’ll need to build you staircase include:

  • Power drill
  • Hammer
  • Tape Measure
  • Leveler

3. Prepare Your Stringers

Your stringers will want to be the length of from the top floor opening forward to where your last step will land (Northern Log can do this for you).

From there, you’ll need to prepare your stringers for mounting. You’ll need to calculate the length and depth of your steps (about 7 to 8 inches is average). Using these measurements, you can draw out and cut each of your slots down the stringer (again, Northern Log can do this for you).

4. Install the Stringers

Attach the two stringers to the wall. Make sure they are equal distances apart at both the top and bottom of the staircase.

5. Predrill the Treads

Your treads should be in relation to the width of your staircase. Predrill the treads for easy installation. You’ll want to create holes on each side of the treads where you’ll anchor them to the stringers.

6. Place the Treads

Next, put the tread on the stringers. Make sure the tread is level before you anchor it to the stringers. Fasten the tread to the stringer with a 3 x ⅜ inch lag that goes through the tread and into the stringer.
