Sydney Wave 10' x 20' Cantilever Carport- Black Aluminium & Corrugated Polycarbonate Roof Panels
The Sydney Cantilever Carport gives you the freedom to park without extra posts. Ideal for turnaround areas or car charging stations, cantilever carports are a great way to protect your vehicle while taking up minimal space. The versatile carport kit boasts panels that transmit sunlight while still providing UV-protection and ample shade, allowing it to work as a flat top carport, patio cover, or outdoor covered lounge area.
Measuring almost 10 feet wide x 20 feet long, this two-legged car shelter is engineered to withstand volatile weather conditions. The ultra resilient polycarbonate carport includes an internal gutter and is 4 in. wider than competitors. The advantage of the unique design is that the Sydney can be installed as a double carport in an apex or wing shape. Protect your vehicle from snow, hail, wind, and UV-rays in a modern and versatile parking carport.

Frequently Asked Questions
1. Do your products come with a warranty?
Yes, all Gradwell Group products come with a manufacturer’s warranty for your peace of mind. Warranty periods vary depending on the product type, but most of our aluminium and GRP ranges offer 10–25 years of coverage against structural defects, corrosion, or weathering.
2. Can you deliver anywhere in the UK?
Absolutely. We offer UK-wide delivery on all products, including large or heavy items such as carports, patio covers, and conservatories. Delivery times may vary based on location and product availability, but we’ll always keep you updated every step of the way.
3. Do I need planning permission for your products?
In most cases, our products do not require planning permission—especially for carports, door canopies, patio covers, and roofline items. However, we always recommend checking with your local planning authority for large installations or if you live in a conservation area or listed building. Our team can provide specifications to assist with your application if needed.
4. Can I install the product myself or do I need a professional?
For larger structures like aluminium carports or lean-to conservatories, we recommend using a qualified installer for best results. We can also arrange professional installation services through our trusted partners.
