Upon entering the building, the size of the vestibule and entrance hall should be noted, and how it is finished; the quality of the wainscoting and its height. If a public hall is wainscoted with marble at least five feet high it will prevent the hand soiling of a decorated wall, which is costly to repair.

A mosaic or marble floor is more expensive and more durable than a ceramic floor. The use of a hard marble is more desirable than a soft one, as soft marble is absorbent and will stain very readily, and after a few years becomes very unsightly. The quality of the marble treads of the stairs and the marble base in the public hall landings should likewise be noted, and as these landings and stairs are being constantly washed, the use of soft marble is particularly undesirable. The marble base should be continued underneath the entrance door trim, in the form of plinth blocks, to prevent the soiling of the trim by the scrubbing to which the tiled floors and base are constantly subjected.

The use of a heavy canvas or wall paper is more desirable than a plain plastered wall for public halls and stairs, particularly in buildings without elevators, as in the latter case trunks and furniture are carried up the stairs, with the resultant breaking and marring of the walls, which would be lessened or avoided by the use of some such material.
