Overall cost: $$. Lumber varies by region, species, and season, so we give a band rather than a figure.

1. Build the first leg set
Tools: Drill / Driver, Miter Saw. Materials: 2x4, 8 ft, Exterior deck screws, 2-3/4", Waterproof wood glue
Lay out one leg set and attach the pieces together at their overlaps with 2-3/4" exterior deck screws. Add exterior wood glue at the joints for strength. The 15° cuts give the trapezoidal splay that lets sections ring a fire pit.
2. Build the mirror leg set
Tools: Drill / Driver, Miter Saw. Materials: 2x4, 8 ft, Exterior deck screws, 2-3/4", Waterproof wood glue
Build the second leg set exactly the same, but mirrored. Confirm the two sets match before decking — a mismatch throws off how the bench meets its neighbors in the ring.
3. Deck the seat
Tools: Drill / Driver. Materials: 2x6, 8 ft, Exterior deck screws, 2-3/4", Waterproof wood glue
Place the twelve 2x6 boards on top and attach, spacing the gaps evenly. Screw down with 2-3/4" screws and glue. The gaps let rain drain so the seat dries between uses. Let cedar silver or finish for exterior use.
