Imagine sitting on a trellis bench, a beautiful vine is creeping up the sides and top, all around you. You can have this serenity in your own garden. Here are the steps to show you how to create this at home oasis.

Tools and Materials Needed:


  •     Four 10 foot 4 by 4 posts
  •     Two 8 foot 2 by 6 beams
  •     One 12 foot 2 by 6 for 3 cross braces
  •     One 8 foot 2 by 6 for 2 seat supports and 3 back supports
  •     Two 8 foot 2 by 4s for 4 bench legs, back rail and lattice support
  •     One 12 foot 2 by 8 for 3 seat planks
  •     One 8 foot 1 by 4 for 2 backrests
  •     One 4 foot 1 by 6 for 2 armrests
  •     Twelve 6 foot 2 by 2s for 4 verticals and 8 slats
  •     One 4 by 4 foot lattice sheet, cut to 3 by 4 foot
  •     4 decorative corner braces
  •     1/4 inch galvanized carriage bolts with nuts and washers: 4 at 3 1/2 inches, 8 at 5 inches, 4 at 6 inches
  •     Twelve 1/4 by 4 inches galvanized lag screws with washers
  •     1 1/4 and 3 inch decking or stainless-steel screws
  •     Exterior stain and sealer or primer and paint

Step 1 - Notch the Beams

In the top of the post, cut 5.5 inches by 1.5 inch deep notches into the top of the posts. Lay out the posts and form a triangle that measures 4 by 5 feet. Adjust the posts so the notches are level with one another. Brace or lightly tap the posts into the soil temporarily. To make a decorative profile, cut the ends of the 2 by 6 beams Place the beams into the notches and secure them from the sides with 2, 5 inch carriage bolts at each intersection.

Step 2 - Add Cross Braces

Cut the cross braces to length and attach them to the posts by drilling holes and driving the lag screws. Two of the cross braces attach to the top of the posts. The longer one (third one) goes on the end opposite of the bench. It should be positioned twelve inches above the ground.

Step 3 - Install the Seat Supports

Cut the back and seat supports to length. Position each seat support beside a post with the top of the support being 16.5 inches above ground. Drill a 1/2 inch hole into the support beam and post and secure it with a 6 inch carriage bolt. Make sure the seat is level and secure it with an additional carriage bolt for support.

Step 4 - Install the Legs

With 3.5 inch carriage bolts, bolt the front legs to the outside of the seat support. Attach the back legs on with 3 inch screws.

Step 5 - Add the Seat

Cut the 2 by 8 into 3, 41 inch planks to make the seat. Make sure it is flush with the back of the seat. Attach the planks with 3 inch screws.

Step 6 - Back Supports

Cut the 18 inch long back supports so they taper from 5.5 inch at the bottom to 2 inches at the top. Align with the back of the seat and attach the supports to the post. Pilot holes then drive 3 inch screws in.

Step 7 - Install the Back Rest

Cut the backrest to length. With 3 inch screws, attach the backrest to the top of the back support. It will stick out some. Attach the second backrest between the first back support and the seat.

Step 8 - Install the Armrests

Cut the armrests to length. With 3 inch screws, attach the top of the arm rest to the top of the legs.

Step 9 - Install the Lattice and Final Pieces


Cut the lattice so it fits snugly and behind the bench. Attach by angling 3 inch pilot holes with screws. Cut the lattice panel to fit and attach with 1 1/4 inch screws to support and poles. Trim the ends with a circular saw in decorative fashion. Finish the arbor with stain or paint it.
