Optimize Your Outdoor Space with a Built-in Bench

Whether you're building a composite deck with Fiberon or TimberTech, or a deck in Quebec with Trex or TruNorth, a built-in bench transforms your space into a welcoming area. Not only does it provide comfortable seating, but it also reinvents the aesthetic of your outdoor design and frees up space for your other furniture.

Why Choose a Built-in Bench?

An embedded bench offers several advantages for your deck:

• Space-saving: say goodbye to bulky chairs, the bench conforms to the structure of your deck.
• Cohesive aesthetic: by using the same material (composite or wood) as your decking, your design remains consistent.
• Conviviality: ideal for entertaining guests, every corner becomes inviting.
• Durability: with premium materials like Fiberon, TimberTech, Trex, and TruNorth, your bench will withstand Quebec's weather.

Required Materials and Tools

Essential Materials

To build an 8 ft long built-in bench, you'll need:

• 1 2x6 board: for seat rails and supports.
• 1 4x4 post: for legs and stabilization.
• 3 1x6 boards: for exterior cladding or finishing.
• 4 2x4 boards: for the internal frame.
• ½ gallon of stain: choose an exterior stain compatible with your composite or wood boards.
• 6 3-3/8” galvanized lag bolts: for securely fastening the structure.
• ½ lb of screws specifically designed for composite or stainless steel.
• Brackets and cleats: to anchor the bench to the decking.

Essential Tools

• Tape measure: precise measurements for a perfect fit.
• Framing square: checking right angles.
• Brushes: for applying stain.
• Clamps: holding pieces during assembly.
• Circular saw and miter saw: clean cutting of 2x6, 2x4, and 4x4 boards.
• Drill/driver: pre-drilling and quick screwing.

Steps for Building a Built-in Bench

Before beginning construction, always consult local codes to ensure your bench does not violate safety standards, especially if it is near a railing.

Step 1: Planning the Placement

For a professional finish, use the same materials as your composite deck or wood decking:

• If your deck is made of Fiberon or TimberTech, opt for composite boards from the same line.
• For a patio made of Trex or TruNorth, ensure that the finishes and colors (e.g., Island Mist, River Rock, or Weathered Teak) match.

Position the bench parallel to the joists for easy anchoring. If you prefer it perpendicular, plan for a support every 4 to 5 ft depending on the joist spacing.

Step 2: Measuring and Assembling the Frame

1. Trace the shape of the frame in your work area.
2. Cut your 2x4s for the final length of the bench minus 4 inches in width and depth.
3. Assemble six cross members inside the frame to distribute loads. Pre-drill each joint with the drill/driver and screw firmly.

Keep the standard seat height at about 16 inches for optimal comfort. You can adjust between 16 and 20 inches according to your preference.

Step 3: Installing the Legs and Supports

1. Cut your 4x4 posts into three equal pairs of legs with the miter saw.
2. For a bench attached to a wall or railing, reduce the height of the back legs by about 1 inch to create a slight backward slope and improve comfort.
3. Screw the 2x6 rails cut to the desired width (generally 16 inches deep) between the front and back legs.

Step 4: Attaching Cleats and Laying Boards

1. Place the cleats on the joists, flush with the edges, for solid support.
2. If your boards (or composite boards) extend more than 6 inches, screw them in before attaching the frame.
3. Pre-stain or apply the finish to flat surfaces before full assembly for a clean look.

Step 5: Laying the Seat Boards

1. Align the first board perpendicular to the railing, screw it in securely.
2. Use a ½ inch slat as a guide to space each subsequent board.
3. Repeat the process until the entire surface of the bench is covered.

Your built-in bench is now ready to welcome family and friends right in the heart of your outdoor living space.
