How to Build Wood Bench Decks

Building the wood bench deck

• 1

  Measure the dimensions of the deck project exactly and lay down string or carpenter's tape to outline the building project exactly. Trying to eyeball where a post hole should be dug is a recipe for disaster. To obtain professional results, treat this project professionally.

• 2

  Dig post holes approximately every 4 to 6 feet apart. Make the depth of the post hole roughly 18 inches. Because this will be the foundation that bears the deck's weight, do not rush or try to stretch out this distance.

• 3

  Sink the vertical beams (4x4 or larger) into the post holes and fill the area around the beam with quick drying concrete. Put the level on the beams during this step to make certain the beams are perfectly upright; you may well need a partner to help you do this reliably.

• 4

  Nail the supporting frame in place, using pre-cut lumber. This bottom frame is what ties the vertical beams together, while providing a flooring system for the wood deck itself.

• 5

  Lay the deck flooring across the cross beams and nail them into place. Make sure you place the board close together but not entirely flush. Boards placed too closely can sometimes expand in the elements, which can lead to cracking and serious deck damage over time.

• 6

  Build the railing system high along the perimeter of the deck, designing a sitting area as part of the railing. This will likely mean taking the need for a backrest into account. The benches should be built from the same lumber as the deck flooring to have a seamless appearance.
