2×4 Deck Bench Plans

by Ovidiu


This step by step diy project is about 2×4 deck bench plans. I have designed this simple deck bench so you can build one from just 2x4s. This deck bench with x shaped legs is sturdy, easy to build and the materials won’t be costly. Make sure you read the local codes, so you comply with the regulations.

Before starting the actual construction you should study attentively the local building codes, to find out whether you need a building permit and if there are some restrictions for your project. Choosing the right location for your deck is essential, so make sure you check if there will get enough light or if it will add character to your property. Using weather-resistant materials is also important, so buy at least pressure-treated lumber. See all my Premium Plans HERE.

Deck Bench from 2x4s Plans



The first step of the project is to build the frame of the legs. Therefore, use 2×4 lumber for the components, as shown in the diagram. Drill pilot holes through the plates and insert 2 1/2″ screws into the vertical post.

Attach 2×4 slats to the top of the legs. Make sure the edges are aligned and leave 1/4″ between the slats. Drill pilot holes through the slats and insert 2 1/2″ screws to secure them into place.

Just built this bench and it came out great. Only had one problem and that was on the trim. It says cut 2 pieces to 49″ and I think it should be 51″. Other than that it was a fun build!
