Planning Your DIY Corner Bench

When deciding on your bench design consider these factors

• Dimensions – Typical corner benches are 4-6 feet on each side. Adjust for your space.

• Seating – Allow at least 15-18 inches depth for comfortable seating.

• Style – Choose a basic square design or get creative with angles.

• Materials – Pressure treated lumber withstands weather Pine or cedar give a nicer look

• Leg height – Standard bench height is 16-18 inches. Adjust if desired.

• Backrest – Add a backrest for extra comfort. Omit for a more open feel.

• Corner angle – 90 degrees is typical. Wider (obtuse) angles take up more space.

• Decor – Leave natural or stain/paint to match your color scheme. Add cushions later.

Constructing the DIY Corner Bench Frame

Follow these steps to build a simple square corner bench frame:

• Cut 2x4s to required lengths with a miter saw.

• Assemble sides of bench by screwing 2x4s together at corners. Check for square.

• Attach front and back 2x4s to side assemblies to create outer frame.

• Add 2×4 supports diagonally across corner for stability.

• Attach 2×4 seat supports inside frame, spaced 16 inches apart.

• Screw 2×4 backrest supports to rear of frame, if including backrest.

• Sand any rough edges. Apply wood sealer/preservative to cut ends.

Adding the Seating

Now add the horizontal 2×4 boards to create the seating surface:

• Lay 2x4s across seat supports, spaced 1/2 inch apart for drainage.

• Put the boards’ front edges 3/4 inch over the front of the frame to give yourself room to grip when you lift the seat.

• Drill pilot holes then drive 3′′ deck screws through boards into seat supports.

• Use shims and clamps to ensure even spacing between boards as you attach them.

• Sand top surface smooth. Round over front edge of seating for comfort.

• Apply weather resistant sealant/stain if desired.

Creating a Backrest

For extra comfort, attach a simple 2×4 backrest:

• Lay 2x4s horizontally across backrest supports, 1/2 inch apart.

• Position so tops align with top of seat. Bottom should sit just above seat rear.

• Attach backrest boards by driving screws from rear through supports.

• Sand smooth and finish with sealant or stain to match seat.

Tips for Completing Your DIY Corner Bench

• Add decorative wood trim along edges for a more polished look.

• Attach corner brackets or supports between legs for stability.

• If you stain the whole bench the same color as your deck or outdoor decor, it will look like it belongs together.
