I don't have a foyer in my house...it's more like a teeny, tiny transition space into my living room or a small viewpoint towards our staircase. If I want to take my shoes off or put my shoes on, I sit on the bottom step of our staircase to do it. I actually put two little hooks to hang jackets/hats near our front door just to make it seem like a foyer. But it's not a foyer, it's a "faux"yer. Is it wrong of me to put on our house-hunting wish list a proper foyer? hmmm, more square footage or a proper foyer? decisions decisions.
Anyways, I think I want a foyer because I already know what I want in one: (1) bench; (2) basket (optional) to hold shoes/mail/doodads; (3) a large enough wall to hang either coat hooks/rack or a large painting or a gallery wall. Simple, but functional all around - my kind of space.
