Briefing

First of all a video of the location:

I will use this terrace for bbqs, brunches and evening/night parties.
I'd like to have a small pool like tubes or hydro.
Also green planning around will be very appreciated.
I also attached a "my first idea" but please forget it an feel free to create.
For covering i saw something like this: http://www.brianzatende.it/it/esterno/scheda.jsp?codice=151
