A wooden bench that I designed to go on my porch.

Materials Needed

Parts:
Seat - 1 board 1000mm x 400mm
Backrest - 1 board 1000mm x 200mm
Front legs - 2 boards 70mm x 420mm
Rear legs - 2 boards 70mm x 730mm (marking 420mm from the leg, I made a diagonal cut at the top to the middle of the boards (35mm))
Front and rear reinforcement - 2 boards 1000mm x 50mm
Side reinforcement - 2 boards 260mm x 50mm
Central reinforcement - 1 board 364mm x 50mm (this measurement will depend on the thickness of the wood you are using)
Wood glue
Can be fixed with wooden dowels or with nails and/or screws.
12 metal corner brackets
24 wood screws 3.5 x 14

Tools Needed
Saw (jigsaw, circular saw, handsaw, or table saw) - You can choose to order the wood already cut, but this will be an additional cost.
Hammer.
Carpenter's clamps.
Phillips screwdriver.

Steps
Preparation
Separate all the pre-cut pieces. If using wooden dowels, drill the holes, ensuring they are well aligned.

Assembly
Begin assembly from the sides, joining the front and rear legs with the side reinforcement board using wood glue and nails, screws, or dowels.

2- Assemble the front and rear reinforcement structure by attaching it to the central reinforcement board using wood glue and nails, screws, or dowels.

3- Join one of the sides to the structure assembled in the last step and also add the backrest, using wood glue and nails or screws or dowels.

4- Make sure the backrest is angled for greater comfort.

5- Attach the other side to the bench frame using wood glue and nails, screws, or dowels.

6- Finish by fitting the seat into the bench frame and securing it with the metal corner brackets.
