Pergola Plans

Wood Pergola Plan by HGTV

Pergolas provide some much needed shade from the summer sun. Learn how to build a pergola with these step-by-step instructions.

Materials Needed:

  • gravel
  • 4" x 4" pressure-treated posts
  • 2" x 4" pressure-treated boards
  • 2" x 6" pressure-treated boards
  • 2" x 10" pressure-treated boards
  • galvanized deck screws
  • circular saw
  • level
  • shovel
  • wheelbarrow
  • socket set
  • screwdriver
  • drill
  • hammer
  • spade
  • post hole digger
  • ladder
  • jigsaw

Steps:

1. Select the site for the pergola and mark the placement of the four posts. Use a post-hole digger or two-person auger to dig holes to a depth of 24" and width of 9". Add a few inches of gravel to the bottom of the holes for drainage. Insert 4" x 4" posts in holes. Ensure the posts are level and plumb. Attach temporary 2" x 4" bracing to hold in place. Mix fast-drying cement according to the manufacturer's directions and pour into holes. Let cure for 24 hours.

2. Cut joist beams from 2" x 10" boards to span the pergola posts. To create a decorative look on the end of the joist beams, draw a straight or curved design on the wood and cut along the line with a jigsaw. Temporarily clamp in place while holes are drilled through the beams and posts. Attach the beams to the posts using 3" lag bolts.

3. Cut the stringers from 2" x 6" boards to span and overhang the joist beams. To create a decorative look on the end of the stringers, draw a straight or curved design on the wood and cut along the line with a jigsaw. Evenly space the stringers perpendicular to the beams and toenail in place using 3" galvanized deck screws.
