Sizing a triple or four-bay carport
Triple carports and four-bay carports start at R19,000 in Pretoria. Count the widest thing you park, not just the cars. A 9m × 6m triple takes three sedans, or two cars and a single-axle trailer; a 12m × 6m four-bay takes four vehicles, or a boat-and-trailer plus two cars. On a plot the span often needs a taller 2.7–3.0 m beam for a bakkie with a canopy or a horsebox, and a mid-post layout the boat can reverse between.
| Structure | Size | Typical use | Price band |
|---|---|---|---|
| Triple | 9m × 6m | 3 cars, or 2 + trailer | R19,000 – R38,000 |
| Four-bay | 12m × 6m | 4 vehicles / boat + cars | R27,000 – R52,000 |
Wide spans, sun and hail
A wide roof catches more sun, hail and wind, so the engineering matters more on a triple than on a single. KB Carports uses heavier galvanised steel sections and full-length IBR runs on these spans, with the roof pitched to shed a Highveld downpour fast and reflect the bushveld heat off the vehicles below. The gauge-and-pitch reasoning also feeds the sun, heat and UV guide.
Where triples get built
Most triple and four-bay work is on the plot belts — the Cullinan and Rayton smallholdings east of the city, the Roodeplaat and Bon Accord holdings to the north, and the eastern agricultural stands — where there is room. Price the exact span on the carport prices in Pretoria page, or start with a double carport if the third bay can wait.
Triple and four-bay frames are the largest of the carports in Pretoria KB builds, and they use the same galvanised sections as the smaller sizes with heavier beams.
Common questions
How much is a triple carport in Pretoria?
A triple carport in Pretoria costs R19,000–R38,000 supplied and installed at 9m × 6m in galvanised steel with IBR roofing. A four-bay (12m × 6m) runs R27,000–R52,000.
What size carport covers a boat and trailer?
A four-bay 12m × 6m carport, or a triple with an extended bay, covers a boat-and-trailer alongside two cars. Specify a 2.7–3.0 m beam height so a boat on a trailer or a bakkie with a canopy clears the roof.
Can you build a large carport on a plot or smallholding?
Yes. The plot belts around Cullinan, Rayton and Bon Accord are where most triple and four-bay carports go, using heavier steel sections and taller beams for trailers, boats and caravans.
