Build your own DIY deck with bench seating. This film documents all the steps involved in building a funky deck. It takes deck building in a new direction by adding a perimeter bench seat and bespoke pathway. Made by hand and complete from framing to finishing, The Dirt Effect explains the process in his own unique way.
Using the image above, and your measurements for your deck make a list of how many 2 x 6s you will need for the bench fronts, seats, back supports, and top plate. Make sure you do this for each bench you plan to build! For example: I would need (9) 2″ x 6″ x 120″ for the bench shown above.
Benches built parallel to the joists can be any length. You can build both types on the same deck. It's easiest to frame built-in benches before the decking goes on. Bench seats should be about 18 inches above the decking and 15-30 inches deep. Built-in perimeter benches help define the edge of a deck in addition to increasing the seating.
Under no circumstances can any type of bench, even built in benches with a back, be used as a guard on any deck higher than 24 inches above grade. Be familiar with local building codes in your area to ensure bench placement passes building code standards. A standard bench for a deck is 18” tall. Two 4x4 support legs with 2x6 framing and trim is common construction. Benches are built two or three boards wide on a 2X6 frame.
