I have a Colonial Revival, built in 1922. The kitchen was redone inexpensively sometime in the past, and I am going to re-redo it in the spring. I'm putting in marmoleum floors, soapstone counters and subway tile with oak cabinets. I'm pretty sure that the original kitchen was unfitted; I'm not going to go that far in restoration, but I want the kitchen to be period-appropriate.
The door to the dining room is a folding louvered door which is screamingly anachronistic. Since every doorway in this house had a door at one time (many have been removed and are stacked in the basement), I'm almost certain that the kitchen-dining room door was a swinging butler's door. All of the other doorways from which doors were removed still have hinges on the woodwork and strikeplates for the latches, but this doorway has unmarred woodwork, and signs in the floor that the mechanism for the swinging door was there at one time and had been removed. Sadly, the doors in the basement all have hinges and doorknobs; not one swinging door in the bunch, so apparently it was discarded when it was removed.
The contractor who is doing my kitchen agrees with me that it's almost certain that a swinging butler's door used to be there and feels that it would be a simple matter to put one back in. We have a friendly disagreement, though, about whether or not there would have been a window in the door. My mind's eye sees a square, rotated 45 degrees so it's oriented like a diamond. Or an oval, perhaps, oriented with the long axis up. My designer feels that there would not have been a window. I know that my dining room never had a bell or buzzer under the table to let the maid know when to bring in the next course, so it's my contention that she had to be able to monitor the progress of the meal through the window. (Can you tell we're having a lot of fun with this?)
Anyway, what's your best guess? Window? No window? What shape? Stupid idea all around? What?
