A pergola has an open or partially open roof, while a pavilion has a solid roof and a gazebo is usually a freestanding, roofed structure with a distinct shape. The right choice depends on how much shade and rain protection you need, how much space you have, and how the structure will be used.

What is a pergola?

A pergola is an outdoor structure with posts and beams supporting an open or slatted roof. It provides shade while still allowing air and some sunlight through. Some designs can use additional shade features, but a standard pergola is not a waterproof shelter.

Pergolas work well over patios, seating areas, outdoor kitchens, and walkways. In Charleston and Folly Beach, the open design can be useful because it provides shade without enclosing the space.

Pros: Open feel, good airflow, shade, and flexible placement.

Cons: Limited protection from heavy rain and wind-driven weather.

 

What is a pavilion?

A pavilion is generally an open-sided structure with a solid roof. Unlike a pergola, the roof is designed to provide much stronger protection from sun and rain. Pavilions are often used for larger outdoor living areas, dining spaces, and outdoor kitchens.

A solid roof can be especially useful in the Lowcountry, where summer heat, humidity, and heavy rain can make an uncovered patio difficult to use. The roof structure also adds more weight and construction requirements than an open pergola.

Pros: Better rain and sun protection and more usable shelter.

Cons: Usually requires more structure, space, and planning than a pergola.

What is a gazebo?

A gazebo is typically a freestanding roofed structure, often with a polygonal or rounded footprint. It is commonly placed as a separate destination in a yard rather than directly over a patio or outdoor kitchen.

Gazebos can provide shade and rain protection, but their shape can make them less practical for rectangular patio layouts. They may also require more careful placement around existing landscaping, drainage, and property setbacks.

Pros: Defined outdoor space and strong shade and weather protection.

Cons: The footprint and shape may limit furniture and kitchen layouts.

Which structure is best for a patio, kitchen, or pool?

Think about how you expect to use the space. A pergola can work well over a seating area or patio where you mainly want shade. A pavilion is more suitable when rain protection is important, particularly over an outdoor kitchen or dining area.

For a pool area, either can work depending on the layout. A gazebo can create a separate shaded destination, while a pergola can provide shade beside the pool without making the area feel enclosed.

What affects the cost of a pergola, pavilion, or gazebo?

There is no single price because construction varies by size, materials, roof design, attachment method, site conditions, and required structural work. A solid-roof pavilion generally involves more roofing and structural components than an open pergola.

In Charleston-area projects, the site also matters. Sandy or clay soils, drainage conditions, high water tables, and exposure to salt air can affect construction details and material choices.

Do you need a permit or HOA approval?

Permit requirements depend on the structure, property, location, and applicable building codes. Setbacks, structural requirements, electrical work, and roof construction can all affect what approvals are needed.

Homeowners in Folly Beach and the greater Charleston area should check local requirements before construction. If your property is governed by an HOA, review its architectural rules as well.

How do you choose between them?

•Decide whether you need shade only or meaningful rain protection.

•Measure the area and consider furniture, cooking, walking paths, and pool access.

•Check drainage, soil, setbacks, and existing utilities.

•Review local code and HOA requirements.

•Compare materials and construction details based on how you will use the space.

 

Frequently asked questions

•Is a pergola waterproof?

A typical pergola is not waterproof because its roof is open or slatted. A solid roof is needed for substantial rain protection.

•Is a pavilion better for an outdoor kitchen?

A pavilion can be a practical choice when you want a solid roof over the kitchen and dining area. Layout and ventilation requirements should be considered during design.

•Can a pergola be attached to a house?

Yes, depending on the design and property. An attached structure requires proper structural connections and may have additional code requirements.

•Which is better for a small patio?

A pergola may fit more easily because its open structure can provide shade without requiring a full roof system. The available footprint still needs to be checked.

•Planning your outdoor structure

We can help homeowners in Charleston and the surrounding Lowcountry compare options based on the actual site and intended use. Every project starts with a free design and build estimate, including an on-site visit and three price points for the same scope at different material levels. Once a project is booked, we create a custom 3D design so you can review the planned structure before construction.
