How to Build a Small Pergola

Pergolas are used for creating secluded areas.

Pergolas provide a supported structure for climbing plants and a natural shaded area on hot summer days. Wood is the cheapest and most commonly used construction material used to build a pergola, although brick, stone or metal can also be used. Pergolas are generally used to link sections of the garden or drape walkways. Ensure that the area is large enough for the structure and the ground is level and clear of debris before starting construction. Mark where the support posts will be positioned. Ideally, they should be six feet apart, arranged in a square shape. Stain or paint the wood before assembling the pergola.

Things You'll Need

• 4 wooden posts 3.3- by 3.3 inches by 9.8 feet
• 2 wooden cross members 1.3- by 1.3 inches by 5.9 feet
• Wooden beams 1.7- by 3.7-inches by 9.8 feet
• Lag bolts
• Countersunk stainless steel screws
• Ballast and cement
• Cordless drill
• Wood saw
• Shovel
• Spirit level
• Spare battening
• Step ladders

Instructions

1. Dig four holes 2-feet deep and 1-foot square for the wooden posts. Position the posts and secure by screwing the spare battening between the posts so they stand independently.

2. Pack the ballast tightly around the bottom of each post and use the spirit level to check that they are straight. Mix the cement and pour into each hole. Allow the cement to dry for at least 24 hours.

3. Remove the spare battening. Drill holes through each end of the cross members and the top of the posts to secure with the lag bolts.

4. Position and bolt the cross members between the two sets of posts. The structure will now look like two soccer goals facing each other.

5. Space the wooden beams across the top of the structure evenly and secure with screws fastening into the cross members. Saw the ends of the beams at an angle to produce a beam effect.

6. 

   A pergola provides a cover for entrances and walkways.

   Secure trellises to the sides of the pergola for a more enclosed look. Plant climbers around the base of the wooden posts or position pots around the trellises inside the pergola.

Tips & Warnings

• The cement must be fully dried and the posts standing unaided before you continue.

• Use ready mixed fast-drying cement for quicker results.

• Use wire to help support the climbing plants.

• Cement powder is an irritant so wear gloves and safety equipment when mixing it. Do not attempt to use cement in rainy weather or in damp conditions.
