Spiral staircase. Perhaps a bit wider so it can accommodate a small lift to be installed in the middle. No carpet runner, and branches off to each floor. Ideally, the library would be kinda open, with this in the center.
exterior "look" grayish wood siding, sleek white smooth stucco, dark anodized doors, lighter exterior concrete color. disregard the pool and pretend there are two homes haha.. we need to discuss- are we doing board formed concrete? or tile for the third element?
