Rooftop Concept Art

I'm starting off by planning what assets are going to be on the main rooftop, I've drawn out a little plan just below, to help me design.

I've also did a quick sketch of what I would like the Rooftop door to look like, just below.

Below I have drawn out a little sketch of what I would like to occupy the rooftop, it's basically the assets I have named in the plan picture at the top of the page. With a quick sketch of the building next to building #1 of what will occupy that rooftop.
