When houses began to be built more than a single story in height, the staircase became an important feature of the hall, and balconies were also introduced overlooking this great room, which was often the full height of the building. In fact, balconies were for a time more conspicuous than staircases, which were frequently located in any convenient secluded place. However, as builders came to appreciate more fully the attractiveness of this utilitarian structure, when embellished with suitable ornament, the staircase was accorded a more prominent position. Eventually it became the most important architectural feature of the hall, for the most part supplanting the balcony, which was in a measure replaced by the broad landings of broken, winding and wing flights. Throughout the Georgian period of English architecture, the hall of the better houses retained something of the size and aspect of the great halls of feudal days, while at the same time accommodating the staircase and serving as a passageway leading to the principal rooms on the various floors. In the more pretentious houses of the period they were the scene of dancing and banqueting on special occasions, and for that reason were of spacious size, often running entirely through the building from front to back with the staircase located in a smaller side hall adjoining. Where space or expense were considerations, or where spacious parlors and drawing-rooms rendered the use of the hall for social purposes unnecessary, the staircase ascended in various ways at the rear of the main hall, usually beyond a flat or elliptical arch, where it added very materially to the effectiveness of the apartment without detracting at all from the use of the front portion as a reception room. Such halls as the latter are as typical of the better Provincial mansions of Philadelphia, especially its countryseats, as of the plantation houses of Virginia and the early settled communities farther south. In the city residences of Philadelphia, built in blocks as elsewhere, the halls were of necessity narrower, mere passageways notable chiefly for their well-designed staircases, which consisted for the most part of a long straight run along one side with a single turn near the top to the second-floor passageway directly above that to the rear of the house on the floor below. In a few of the earlier country houses there are, however, halls reminiscent of medieval times, for the influences of the mother country were very strong in Philadelphia, and its Colonial architecture displays marked Georgian tendencies, some of it the very earliest Georgian characteristics still somewhat influenced by the life and manners of the Elizabethan and Jacobean periods.
