How to Build a Pergola Frame

Pergolas offer balance between shade and sunlight and can be woven with vines for added beauty. They can be freestanding or attached to the house.

Depending on the homeowner, they can also support decorative elements like lighting, hanging baskets and wind chimes. Staining the wood enhances its appearance and protects it from early breakdown.

Posts

A pergola is typically anchored to a concrete surface or pier (Figure 2). While you can build your pergola over a deck if desired, the best approach is to anchor posts directly into the poured concrete patio. This provides greater stability for the structure and helps protect against soil heaving and post rot/breakdown. Hammer set fasteners are usually used to anchor the posts into concrete – they can be set easily and quickly.

The posts in a pergola frame are the cornerstone of the design; they support the rafters and help to create a unique architectural effect. They can be anchored in several ways including notching the posts, attaching them to the side, or laying the beams on top of the post secured with hardware plates.

If your pergola is being built over a paved area, the posts must be sunk to a footing (Figure 1). There are many options for this type of foundation but a contractor can use a helical pier which is screwed into the ground much quicker and more efficiently than mixing and pouring a traditional concrete footing.

Beams

A pergola offers a stylish, shaded area for outdoor relaxing and entertaining. Decorative elements like wind chimes, hanging baskets and plants, and a variety of lighting options can add to its appeal.

Running horizontally atop vertical posts, the beams in a pergola offer structural height and sturdiness. They also form the framework for a variety of other features, including vining plants and ornaments.

Depending on the style, some pergola designs feature rafters that offer more or less shading. The spacing between the rafters and the height of each rafter helps to determine this.

For an even more distinctive appearance, many homeowners choose to stain their pergolas to add a desired color and protect the wood from damage caused by rain and sunlight. This can help the structure last longer and increase its durability. For additional functionality, some pergola designs include louvers on the roof that can be manually or motorized operated to open and close the canopy for air circulation or to offer sunshine as needed.

Rafters

Pergolas allow you to enjoy the benefits of sunshine without getting blasted by UV rays. This combination of sun and shade helps you relax and refreshes your skin. But too much UV can lead to painful burns and vitamin D deficiencies. Pergolas offer the ideal amount of shade to prevent those problems while still providing a dappled environment that makes you feel like you’re sitting under a cloud.

A pergola is often adorned with vines or other climbing plants that add beauty and interest to the structure. Lattice trellis can also be installed to accommodate vining greens that enhance the look of the pergola while adding even more shade. Staining the wood can further customize your pergola to match your outdoor living space. For a more architectural look, skilled carpenters can engineer mortise and tenon connections to give the frame a timber-frame appearance. This requires a level of skill and precision not found in many pergola kits.

Roof

The roof is an important component of a pergola. It offers shade and protects furniture from rain and sun. It also enhances the aesthetic. For a more appealing look, choose a material that coordinates with your home design.

Different materials can be used for the roof of a pergola. Aluminum, vinyl, and cedar are common options. A professional contractor will help you determine the right choice for your outdoor space. They will also know how to navigate local building codes and permits.

Choosing the best structure for your garden will allow you to fully enjoy leisure activities. Pergolas offer a beautiful alternative to shaded seating areas and can be built in a variety of shapes and sizes. They can be placed around a patio, pool, or other feature of your garden. You can even use them to connect different parts of your garden. For example, you can attach lattice work to a pergola to give twining plants, such as wisteria and bougainvillea, something to grow on.
