Stairways.
Stairs are a necessity, and their comfort and sightliness depend on several features. Steps must be broad and deep, landings wide and windowed, if may be. If they must be crowded into a narrow hallway it is better that they be made deep and sloping as space permits, and then inclosed with an archway and curtain at foot instead of a door. This also saves heat. But where the great square reception hall can be devoted to them they may be made a thing of beauty.
