Indoor-outdoor living is not a new concept, but certain features and clever design choices make connecting your interior and exterior spaces much more seamless. Case in point: pergolas.

These slatted outdoor shade structures date back to ancient Egypt, where wooden designs beautified temples and gardens. Since then, pergolas have only gotten more useful — and more interesting. That can be credited to new, more durable materials, diverse designs and styles, convenient pre-built pergola kits, and comfort-focused accessories.

If you’re pondering a pergola for your backyard, look to this guide for help. We cover pre-purchase considerations, pros and cons, various types, and other useful information that can help you make the right decision.

Things to Know Before Buying a Pergola

Whether you shop POLYWOOD or elsewhere for a pergola kit, you’ll need to be privy to a few key items.

It’s an Advanced Project

You’ll need a certain set of skills to properly install your pergola — a knack for carpentry, power tool know-how, etc. If you don’t have this experience, save time and stress by hiring professional contractors to complete the project for you.

If you choose a POLYWOOD pergola, you can opt for White Glove Delivery when placing your order. This all-inclusive service includes delivery, assembly, professional installation, and removal of all packaging materials.

Time & Tools Are Required

If you plan to DIY, we recommend enlisting the help of a friend (or two) and setting aside a few hours to complete the build.

And in addition to pergola building materials, you’ll need a mix of tools at your disposal:

  • Safety gear: Goggles, hard hats, work gloves, ear protection, and steel-toed shoes.
  • Pencil: For marking lines and hole placements on lumber.
  • Tape measure: To get lumber and site dimensions.
  • Chalk line: To ensure straight lines and an accurate footprint.
  • Shovel and post-hole digger: If you plan to dig holes for in-ground concrete footings, you’ll need these.
  • Speed square: For checking 90-degree angles on vertical posts and horizontal beams.
  • Spirit and post levels: These help ensure posts and beams are straight and level.
  • Wrench or socket set: To tighten nuts and bolts.
  • Hammer drill: This will help you anchor pergola posts into existing concrete.
  • Ladder or scaffolding: Pergolas are tall — these will help you reach the top beams and rafters.
  • Drill and impact driver: To drill pilot holes and drive in screws and lag bolts.

You Might Need Permits & Permissions

Check with your local planning, zoning, and building departments to find out what (if any) permits are required. And if your neighborhood has an HOA, look over the covenant to see if pergolas are allowed.

Locating Underground Utilities Matters

If installation requires digging, it’s crucial to know where gas pipes, sewer lines, electricity cables, and other buried utilities run on your property. Avoid dangerous accidents and costly repairs by hiring a utility company or your local municipality to locate and mark underground utilities before you dig.

You Need Room to Build

At least three feet of clearance is recommended on all sides of a pergola to accommodate wheelchair users and allow ample room to walk.

What Makes Pergolas Worth the Investment?

Aesthetic Appeal

A pergola adds dimension to a space — which makes it more attractive and interesting — using height, light, layers, and zones.

  • Height: The tall structure guides the eye up to prevent the room from feeling flat.
  • Light: Overhead rafters filter sunlight and cast shifting shadows that change the texture of the ground and furnishings beneath.
  • Layers: The open beams are the perfect place to hang climbing plants or weave in string lights for warmth, contrast, texture, and enhanced functionality.
  • Zones: A pergola defines a space, clearly separating it from the surrounding areas.

Shade

Pergola roofs cut direct sunlight and heat, and the open sides allow the breeze to flow through, keeping you cool and comfortable on sunny days.

Increased Property Value

A well-built pergola visually creates a usable outdoor room, which can boost your home’s value. According to 2024 Zillow research data, properties with pergolas caught buyers’ eyes more than homes without them, receiving 20% more saves and 24% more shares per day on the real estate marketplace’s platform.

Why POLYWOOD Pergolas Stand Out

Our all-weather pergolas are made with reinforced POLYWOOD lumber. You’ll enjoy the same level of style, all-weather performance, and easy maintenance that comes with all of our products.


Our pergolas are currently offered in POLYWOOD Select™ Natural lumber, a warm golden brown with caramel graining details. As the name suggests, this color fits right in with the natural surroundings and translates beautifully to modern, rustic, traditional, and coastal homes.


POLYWOOD Select™ is our most innovative lumber yet. It’s engineered with Microcell™ technology, which is an innovative, compact microscopic structure for superior moisture resistance. And it features the POLYWOOD GenuineGrain™ finish, offering subtle variations in tone and tactile quality.

Types of Pergolas

Freestanding Pergola

This style can stand on its own anywhere in your yard. 

Best for: Any medium or large outdoor space

Cabana Pergola

A semi-enclosed structure with solid or lattice-style wall panels for extra privacy.

Best for: Swimming pool areas, hot tubs, and intimate dining spaces

Corner Pergola

Designed to fit snugly in the corner of a yard, corner pergolas stand on three posts with a triangular roof.

Best for: Poolside patios and small areas with limited space

Arched Pergola

Unlike other designs, this pergola has a curved roof, which gives it an air of romance.

Best for: Winding walkways, gardens, and entrances

Awning Pergola

These small structures attach directly to exterior walls and don’t need posts for support.

Best for: Entrances, garages, breezeways, and windows

Attached Pergola

One or more sides of this shade structure connect to an exterior wall on your home.

Best for: Outdoor kitchens, dining spaces, and second-story decks

Pergola Roof Styles

  • Open-beam: These roofs feature widely spaced parallel rafters with no intersecting slats.
  • Lattice or cross-hatch: Pergolas with lattice-style roofs have the same parallel rafters as open-beam designs, with a second layer of thin slats running perpendicular to create a crisscross pattern.
  • Retractable canopy: These structures are topped with durable covers that roll up to let in the sun and roll back out when you want shade.
  • Louvered: Louvered pergolas have adjustable slats that allow you to choose the level of light that shines through.

How to Use a Pergola Once It’s Built

There are plenty of ways to put a pergola to work. Here are our favorite ideas.

  • Whimsical garden: An arched pergola laced with Clematis at the entrance to your flower garden or covering a landscaped walking path creates a magical moment.
  • Covered relaxation area: A louvered pergola lets you choose your level of relaxation. Keep the slats closed when the sun’s at its peak, and open them at night when you want to take in the starshine.
  • Privacy by the pool: A poolside pergola with privacy walls creates a secluded space by the water where you can read or sunbathe. Add a comfortable chaise lounge and table to complete the comfortable look, and you’re good to go.

What Furniture Fits Under a Pergola?

The answer to this question depends on the pergola’s size, shape, and the type of furniture you want to use.

For example, POLYWOOD pergolas are offered in two sizes: 8’ x 12’ and 12’ x 12’. We always recommend leaving at least three feet of clearance around furniture in the spots you plan to use as walking paths, like in front of sofas and on the sides of chaise lounges.

Here are our recommended furniture setups:

FAQs

What is a pergola?

A pergola is an outdoor structure that provides partial shade and aesthetic appeal on decks, patios, and similar spaces. They have open sides for easy airflow, and vertical posts that support open-beam, lattice, or louvered roofs. 

How much does a pergola cost?

On average, the total cost of a pergola is roughly $4,200. The price changes depending on the size, materials, labor, and whether it’s a pre-made pergola kit or a custom build.

Is it cheaper to buy or build a pergola?

Building a pergola yourself is generally less expensive because you save money on labor. Pre-fab pergola kits give you a balance of convenience and cost. Custom pergolas are the most expensive due to labor and site-specific construction costs.

Should I buy a standard pergola kit or a custom pergola?

Pergola kits are less expensive and easier to install than custom builds, but cannot be tailored to meet specific design or size requirements. Custom pergolas are more expensive, but can be made to your exact specifications.

How to anchor a pergola?

To properly anchor a pergola, gather the right tools and equipment, such as drills with masonry bits, wrench or socket sets, levels, tape measures, ladders, shovels, and mounting hardware. Then, choose the appropriate mounting method, which will differ based on the surface type.


Concrete Slab

  1. Place the pergola’s posts in their desired locations on the concrete and mark the positions with tape or a pencil.

  2. Drill holes into the marked spots.

  3. Attach post brackets to the concrete with concrete screws or anchor bolts.

  4. Slide each post into the brackets and secure them in place with bolts or screws.

Decking

  1. Place the pergola’s posts in their desired locations on the deck's joist structure and mark their positions.

  2. Fasten post brackets directly to the joists with heavy-duty screws or bolts.

  3. Slide each post into the brackets and secure them in place with bolts or screws.

Pavers

  1. Choose the preferred location of the pergola posts on the pavers and mark their locations.

  2. Lift the pavers in each marked area to expose the base material or ground beneath.

  3. Dig a hole beneath each paver with a shovel or post-hole digger — make sure they're deep enough to create footings that support the posts (at least six inches below the frost line).

  4. Mix up some concrete and pour it into each hole. Let it cure fully — roughly 24 to 48 hours.

  5. Anchor the brackets directly into the cured footings.

  6. Connect the posts to the brackets with bolts or screws, then replace the pavers.

How close can a pergola be to the house?

Leave at least two to four inches of horizontal space between the pergola’s head beam and your home’s exterior, and eight to 12 inches of vertical space between the top of your pergola and any gutters, soffits, and roof overhangs. This extra space ensures adequate air flow, prevents water leaks, and allows room for maintenance.
