Update the visuals for the box that buildings are contained in

[FifthTundraG]

Currently, the floating-box style building box looks fine visually, but the issue becomes that the buildings can't scale easily horizontally, making integration of the scrollbar a difficult task.

Instead, making the building's boxes look more like they do in the mobile version (connected) would make the boxes change width much easier.

oops that was the wrong issue, reopening...
