When I dream, spaces take on lives of their own and come together in ways that are non-traditional, but make sense in that dream.

Stairs wind up to each bedroom. Not the most efficient, but it offers a unique way to preserve the sense of space, and offer each bedroom access to the shared space.
If any of this is hard to visualize, here's a floorplan for the upper level of the house:
