Large Shaded Beach Cabana Design

I’m planning a beach cabana whose primary job is to give generous shade. I only need an initial concept and basic blueprint that covers a shaded footprint of more than 20 sq ft, easy to transport and set up on sand. the cabana itself should be approx 2m x 2m. stand approve 1.8m high, have a single extendable pole in the middle. i also want the edges to be scalloped. if you're looking for inspo, i'm trying to create a rival for cool cabanas. but fancier.

Here’s what I’m looking for:
• Schematic drawing with dimensions and a clear indication of the shaded zone.
• Simple material list—lightweight, corrosion-resistant parts I can source locally.
• Assembly notes so two people can pitch it quickly without power tools.

If you can suggest clever ways to maximise airflow while blocking midday sun, all the better. A straightforward PDF or SketchUp file is fine; no photo-realistic renders required at this stage.
