A few challenges to negotiate here, primarily safety barrier compliance - simplest way is to keep it away from the house have the pool fence lines simple & straight.....maybe consider the fire pit area with integrated built in seating closest to the house, with the pool beyond......resort feel will come from various elements, but typically lush layered planting, balanced surface treatments that respond to an external space that has been "designed" comprehensively to specific function as you would an internal space. Would be worth your while investing in some professional design (an actual architect, not just a landscaper) as these spaces need to be understood as areas to "experience" and this is what our profession specialises in achieving and helping people with....also these areas can become quite expensive so understanding budget and how to manage/distribute it is fundamental to the design decisions Best of luck Cheers PD www.pauldistefanodesign.com

I would talk to your pool builder about the pool detail. They are the experts.

for the banquette to be wide enough to lay on it would need to be at least as deep as a narrow single bed which makes it too wide to sit on comfortably without a very thick back rest or a giant pile of cushions to clutter up the space...why not consider a back and sideless freestanding daybed so the primary purpose is laying down and the sitting to dine is only short term and doesn't need a backrest ....this example or similar with taller legs would be a simple economical way to add the day bed feeling without expensive built ins and two along the window wall could look quite inviting with a simple throw and scatter cushion

I thought you could have doors/windows as long as they were lockable in such a way that they function as a pool safety fence? Though I have no idea if that is still the case and also if it is something than varies or varied in different jurisdictions? If you don't have warm winters you don't want to cover the northern windows with an alfresco, unless it is an opening type roof.
