You've decided you want a garden structure. Something to sit under, entertain beneath, or simply give your outdoor space a sense of purpose. So you start researching - and almost immediately, the terminology starts to blur. Pergola, loggia, gazebo, pagoda. Are they the same thing with different names? Roughly similar? Or genuinely distinct?
The honest answer is that these four structures each have a real identity of their own. They differ in their origins, their roof design, how they sit in a garden, and what they're actually good for. Understanding those differences will save you from making an expensive mistake - and help you land on the right choice for your outdoor space.
Here at Cedar Nursery in Cobham, we talk to homeowners about garden structures every week. This guide covers what each one is, how they compare, and which might suit your garden best.
What Is a Pergola?
A pergola is an open-sided structure with vertical posts supporting a framework of horizontal beams and open rafters overhead. The roof is slatted rather than solid, which means it filters light rather than blocking it entirely. That quality of dappled shade is part of the appeal.
The design has Italian and Mediterranean roots, where pergolas traditionally framed walkways and terraces in warm, sunny climates. In British gardens, they've become one of the most versatile structures you can add - partly because they work equally well as a covered dining area, a shaded walkway, or a frame for climbing plants.
Roses, wisteria, and clematis all thrive when given a pergola to climb. Over a few seasons, the structure becomes part of the planting itself - which is a genuinely beautiful thing to watch develop.
For UK weather, a pergola with a retractable canopy or louvred roof panel is worth considering. It gives you flexibility: open the roof on a warm July evening, close it when the clouds roll in. Timber, aluminium, and composite are all available, each with its own character and maintenance requirements.
Best for: Outdoor dining, walkways, framing a view, or supporting climbing plants. The most versatile of the four structures.
What Is a Loggia?
A loggia is something rather different - and it's the one that most people are least familiar with. The word comes from Italian Renaissance architecture, where a loggia described a covered gallery or corridor open on one or more sides, typically built into the façade of a grand house or villa.
The crucial distinction is this: a loggia is attached to the building. It has a solid roof - not slatted beams - and it functions more like an outdoor room than a freestanding garden feature. Think of it as a covered terrace that is structurally part of the house itself.
In contemporary garden design, the loggia concept has found a new audience. Architects and garden designers use it to describe covered extensions that blur the boundary between inside and outside - often with large sliding doors, polished concrete or stone floors, and a seamless connection to the living space within.
You're unlikely to find a loggia commonly mentioned as it's more relevant to architectural extensions and exclusive design projects than to a typical off-the-shelf purchase. But it's worth knowing what the term means, because it's used increasingly in design conversations.
Best for: Extending your living space outwards. The most architectural of the four - essentially an outdoor room attached to your home.
What Is a Gazebo?
A gazebo is a freestanding structure with a solid roof - typically pointed or domed - and open or partially open sides. Unlike a pergola, it doesn't rely on climbing plants or a canopy to provide shelter. The roof does that job on its own.
The name is thought to be an 18th-century invention - a playful Latin construction meaning "I shall gaze" - which captures something of the gazebo's character. It's designed as a destination within the garden: a place to sit, look out, and enjoy the view.
Gazebos are most commonly octagonal or hexagonal in shape, though square versions exist. Timber is the traditional material, and a well-made timber gazebo has a warmth and solidity that feels genuinely at home in an English garden. Metal and vinyl options are also available, with different trade-offs in terms of cost and longevity.
For UK conditions, the solid roof makes a gazebo genuinely usable across most of the year. You can sit inside during a light summer shower or on a cool autumn afternoon in a way that a pergola simply doesn't allow. If year-round use matters to you, a gazebo is worth serious consideration.
Best for: A sheltered garden retreat, outdoor entertaining, or a strong focal point in a larger garden. The most weather-resilient of the four.
What Is a Pagoda?
A pagoda is defined by its roof - specifically, a tiered roof with multiple levels and characteristically upswept eaves. The form originates in Buddhist religious architecture across China, Japan, and Southeast Asia, and it arrived in Western garden design during the 18th century, when a fashion for chinoiserie swept through European landscape design.
You can see the influence in historic gardens across the country - the Great Pagoda at Kew being the most famous example. In domestic gardens, smaller pagoda-inspired structures are available as decorative buildings, but they remain more ornamental than practical.
The tiered roofline offers some shelter, but a pagoda's real purpose is visual. It makes a bold architectural statement. In a garden with the space to carry it, a pagoda draws the eye and anchors the landscape in a way that few other structures can match.
It's a more specialist choice than the others - and honestly, it suits a particular kind of garden. If you're drawn to formal or Japanese-inspired design, or you have a larger plot where you want a genuine focal point, it's worth exploring. If you're working with a typical suburban garden, a pergola or gazebo will likely serve you better.
Best for: A bold decorative focal point in a larger or formally designed garden. The most ornamental of the four.

Which Structure Is Right for Your Garden?
The right choice depends on three things: how you want to use the space, how much room you have, and the aesthetic you're drawn to.
- Smaller garden? A pergola or compact gazebo will give you structure and shelter without overwhelming the space. A pergola attached to the house is particularly good at making a small garden feel like an extension of the home.
- Larger garden? A gazebo or pagoda can serve as a genuine destination - somewhere to walk to, sit in, and enjoy the garden from a different perspective.
- Love climbing plants? A pergola is the natural choice. Give it a few years and a well-chosen climber, and the structure almost disappears into the planting.
- Want year-round use? A gazebo with solid sides, or a pergola fitted with a louvred or solid canopy roof, offers the most reliable protection against the UK's variable weather.
- Extending your living space? Think about a loggia-style covered terrace attached to the house, or a pergola with a proper canopy roof that connects directly to your back door.
None of these structures is universally right or wrong. It comes down to your garden, your habits, and your taste.
Frequently Asked Questions
What is the difference between a pergola and a gazebo?
A pergola has an open or slatted roof, providing partial shade and a framework for climbing plants. A gazebo has a solid roof and is fully freestanding, offering more reliable shelter and functioning as a dedicated retreat within the garden. A pergola is more flexible in how it can be used; a gazebo offers more protection from the weather.
What is a loggia in garden design?
A loggia is a covered, open-sided gallery or corridor that is attached to a building rather than standing freely in the garden. It has a solid roof and functions more like an outdoor room than a traditional garden structure. In modern garden design, it often describes a covered extension that connects the interior of the home to the garden.
What is a pagoda in a garden?
A pagoda is a decorative garden structure inspired by East Asian architecture, characterised by its tiered roof with upswept eaves at each level. It is primarily ornamental and works best as a striking focal point in a larger or formally designed garden. It offers some shelter but is chosen more for its visual impact than its practical function.
Which garden structure is best for UK weather?
A gazebo or a pergola fitted with a louvred or solid canopy roof offers the best protection from the UK's variable weather. Both allow you to use your outdoor space comfortably even when conditions are unpredictable. A standard open-roofed pergola provides partial shade in summer but limited protection from rain.
Do I need planning permission for a garden structure?
In most cases, garden structures such as pergolas and gazebos fall within permitted development rights for residential properties. However, this depends on the size of the structure, its position within the garden, and whether your property has any specific restrictions - such as being in a conservation area or having had permitted development rights removed. It is always worth checking with your local planning authority before installation.
