Fig. 54 is a plan of a platform stairway with two return, or wing, flights, suitable for a public building. The flights and platform may be wainscoted, and, by the introduction of half newels set against the wall opposite the regular newels, a good structural effect is obtained. The regular and wall newels may be carried up as columns and pilasters, further improving the treatment. The flat, ornamental arches may also be introduced between the newels and half newels, to break up and panel the soffit spaces. For a public stairway of this character, executed in either wood or iron, a better effect is produced by omitting the plaster and showing the framework of the structure.
