psj roof terrace

Briefing

I would like a modern style and include the following elements:
BBQ, Dining area (table and chairs for 4 to 6, sunbeds (2) and living; some plants and light (solar energy as there is no electricity)
Constraints: no structural works as I do not own the area, I can only use it
Area is very windy so low plants and no umbrellas but I would like to add a shadowed area if there is a viable solution
