Ive seen these Dutch doors used for a childs room or play room. Kind of like a baby gate so you can keep them from crawling all over the house but still be able to hear them playing. home-front-door-lanai-porch-patio
Neat floor and door. The addition has a separate entry with stairs to the second-floor family room. Built-in cabinets and drawers under the stairs provide space for storage and house a sound system. Shiplap siding and a brick floor keep the space casual.
