Think of a door that has simply been left unlocked. Nobody at the door is checking a list, nobody had to be invited, and behind the door there is something worth seeing — a home, a classroom, a house that is for sale. For as long as the door stays open, anyone may walk in, look, and walk out again.
可以想成一扇沒有上鎖的門。門後面有東西可以看：一個家、一間教室、一間要賣的房子。門口沒有人對名單，也不用邀請函。在門開著的那段時間裡，誰都可以走進去看看，看完就走。一種想法是：open house 講的其實不是房子，而是「門開著的那段時間」——這段時間可以長到好幾年（英式的 keep open house），也可以短到一個下午（星期天的開放看屋）。
