When the homeowners and their parents open up the front door to the Broadview Sunset House, they enter a foyer with coat closets, a soaring steel staircase going up to the second floor, and a door to the Broadview Sunset ADU. The homeowners walk up the stairs to their home, and the parents open the door to theirs. This one-bedroom ADU is entirely located on the ground floor of the house, and just like the upper two floors, has its own private deck opening up to the west and views of the sunset.
