Pergolas shade a patio, walkway or garden seating area with an open slatted roof, spanning about 3 m between posts before the beam sections have to grow. KB Carports designs, manufactures and installs pergolas across Cape Town in timber, steel and aluminium — freestanding in the garden, or attached to the house over a patio or entrance.
Want the same slatted roof over your parking instead? That variant is a pergola-style carport — see carport prices for what it costs.

What a pergola gives you
An open beam roof instead of a solid one: partial shade, with sunlight filtering through, plus protection from the sun’s harsh rays and light rain.
- Partial shade, open feel: the open structure keeps the space airy where a solid roof closes it in, while still shading the vehicle and the area under it.
- Garden integration: the open beams take climbing plants, which turns the carport into part of the garden rather than a structure parked next to it.
- Aesthetic appeal: open beam design and decorative elements add visual interest and curb appeal.
- Design range: styles run from classic and romantic to modern and minimalist, to match different architecture and garden aesthetics.
The defining attribute of a pergola is the open roof: beams or slats with gaps between them, so light and air still come through and rain does not. If you want the same structure with a solid roof that keeps the weather off completely, that is a patio covers in Cape Town, not a pergola.
Pergola design styles
| Style | Detail | Suits |
|---|---|---|
| Classic | Evenly spaced beams with decorative elements such as curved rafters or ornate posts | A romantic, timeless look |
| Modern | Straight beams and simple posts in steel or aluminium | Clean lines and minimalist, contemporary properties |
| Garden | Wider beam spacing for more sunlight, trellises for climbers, natural wood or wood-look materials | Planting-led gardens |
| Attached | Extends from the home’s roofline | A covered walkway or patio combined with vehicle parking |
| Freestanding | Stands independently in the garden or driveway | A focal point and a distinct shaded area |
“Pergola with a roof” — what people actually mean
A large share of pergola enquiries arrive worded as a roofed pergola or a pergola with a roof, which is a contradiction in the strict sense: the open roof is the thing that makes a pergola a pergola. In practice the phrase means one of three builds, and naming which one you want saves a site visit.
- A pergola with closer-spaced slats — still open, but the beams are set nearer together so the structure throws real shade at midday instead of stripes. Rain still comes through.
- A pergola with a polycarbonate sheet over the beams — the pergola frame and look, with a translucent roof laid on top. Keeps rain off and most of the light. This is the usual answer.
- A solid roof on pergola-style posts — at this point the structure is a patio cover with pergola detailing, and it is priced and built as one.
All three are things we build. The distinction matters because the roof decides the footing and beam sizing: an open slatted roof carries almost no wind uplift, while a sheeted roof turns the same frame into a sail and needs heavier posts and deeper footings.
Pergola materials — timber, steel & aluminium
| Material | Character | Maintenance |
|---|---|---|
| Treated timber | Pressure-treated for a wood look with increased resistance to rot and insects | Requires regular maintenance |
| Composite wood | Recycled plastic and wood fibres with a wood-like appearance | Low maintenance; resists weather and insects |
| Steel | Robust strength; carries decorative elements well | Galvanisation is essential in South Africa |
| Aluminium | Lightweight, rust-resistant, sleek and modern | Low maintenance |
The full range of material choices sits alongside the other structures KB Carports builds. We install custom carports in Cape Town, pergola structures included.
Integrating a pergola with the garden
- Climbing plants: vines, jasmine or bougainvillea grown over the structure form a living, green carport roof.
- Landscaping: complementary plants, paving and garden features around the carport tie it into the rest of the garden.
- Seating and features: outdoor seating, benches or a small water feature under or near the structure turn it into a garden retreat.
- Lighting: outdoor lighting built into the pergola keeps the structure usable and attractive at night.
What a pergola costs
A pergola is quoted per site, because almost nothing about it is standard — the span, the post count, the timber section and whether it is freestanding or tied into the house all move the number. As a rough frame, a pergola sits below a solid-roofed structure of the same footprint, because there is no sheeting, no waterproofing and no gutter line to pay for. For comparison, published rates for roofed structures start at R13 500 for a 6 m × 6 m shade-net double — see carport prices in Cape Town.
What actually drives a pergola quote:
- Timber section and species — the single biggest line item.
- Span between posts — beam depth rises quickly past about 3 m.
- Freestanding or attached — attaching to the house saves a row of posts and footings but adds a flashing and fixing detail.
- Finish — sealed, stained or left to grey off.
Wooden pergolas
Timber is what most people picture, and it is what most of our pergolas are built from. The grain and the shadow a timber beam throws are the reason to choose it — a steel pergola of the same dimensions reads as a frame, a timber one reads as a garden structure.
The trade-off is upkeep. Cape Town gives timber a hard year: winter rain from the north-west, then months of UV. Left untreated, exposed timber greys off and the surface checks. Sealed on a cycle, the same structure holds its colour indefinitely. We build in treated pine as the standard and in hardwood where the budget allows, using the same sections and the same crews as our wooden carports.
Pergola sizes and post spacing
Two numbers decide a pergola: how far the beams span between posts, and how far apart the slats sit on top. The first is structural, the second is what actually determines how much shade you get.
| Slat spacing | Shade at midday | Reads as |
|---|---|---|
| Wide — gaps larger than the slat | Light, striped | Structure and framing, minimal shade |
| Equal — gap matches the slat | Roughly half | The usual choice |
| Close — gap smaller than the slat | Most of the footprint | Near-solid, still open to air and rain |
Slat direction matters as much as spacing. Running the slats north–south throws moving shade across the day; running them east–west holds shade over one strip and leaves the rest in sun. On a west-facing patio, where the late-afternoon sun is the actual problem, the slats usually need to run north–south and sit closer together than the owner first expects.
Is a pergola right for your property?
It suits homeowners who weigh appearance and garden integration as heavily as vehicle cover, and who accept partial shade and cover against light rain in exchange for an open, ventilated structure. Contact us for a pergola carport design consultation.
