Love the white house, with the grey/green "greige" door and trim. I think you could do the door/shutters in the grey color and the house and porch white. Or, the house white, the porch/trim in the greige. and the do the shutters and door black.
Beam and floor color - Rough hewn, hand scraped wooden beams create coffered ceiling; brick paver, reclaimed wood floors, arched doorways, and neutral decor in an open concept give us so much to love here.
