In domestic architecture Palladian windows were employed chiefly to light the stairway landing, as at Whitby Hall; to light the upper hall, as at Mount Pleasant; and rarely to light the principal rooms each side of the front entrance, as at The Woodlands. They not only charm the eye as interior features, but when viewed outdoors relieve the severity of many ranging square-headed windows and provide a center of interest in the fenestration, lending grace and distinction to the entire facade. No Palladian windows in Philadelphia so thoroughly please the eye or so convincingly indicate the delightful accord that may exist between gray ledge-stone masonry and white woodwork as those set within recessed arches at The Woodlands. The proportion and simple, clean-cut detail throughout are exquisite. The engaged colonnettes of the mullions contrast pleasingly with the pilasters of the frame, each of the two supporting an entablature notable for its fine-scale dentil course, and these two in turn supporting a keyed, molded arch. The central window has twelve-paned upper and lower sliding sashes with an attractively spaced fanlight above. The narrow ten-paned side windows are stationary. Unusual as is the use of these Palladian windows, their charm is undeniable, and they are among the chief distinctions of the house.

There guests are welcomed to the fireside, and there their first impressions of the home are formed. The architectural treatment of the hall sets the keynote of the entire home interior, so to speak. Its doorways and open arches frame vistas of the principal adjoining rooms, and its staircase, usually winding, affords a more or less complete survey of the whole house from various altitudes and angles. It is the place where the master puts his best foot foremost, as the expression goes, and happily the recognized utilitarian features of the typical Colonial hall permit a notable degree of elaboration at once consistent and beautiful. Throughout the feudal period of the Middle Ages the hall was the main and often the only living, reception and banquet room of castles, palaces and manor houses. It was the common center of home activities. There the lord and family retainers, servants and visitors were accommodated, and all the common life of the household was carried on. In early times there were, besides the hall, only a few sleeping rooms, even in the greatest establishments. Later, more retired rooms were added, and gradually the hall became more and more an entranceway or passageway in the house, communicating with its different parts.
