The most characteristic essential of domestic architecture in Holland is the steeply-pitched gable. It was derived from Gothic sources. Gables owning this influence almost invariably have the lines of their two ascending sides broken by a series of steps which continue upwards from base to apex. They are consequently called "stepped," and such gables will be observed in the drawing from Middelburg mentioned above. The acute rake of the gables determined the slant of the roofs. This circumstance, together with the fact that houses usually had little frontage to the streets, gave great roof spaces incapable of being adequately lighted by windows inserted in the walls. So the fore part consisted of a room (or rooms) which was generally assigned to servants, and the rear area, lighted by dormers, was used for storing and kindred purposes, one all-important among the latter being that of "drying washing." These dormers were quite important factors in architectural composition; each had hinged and painted shutters and a little steep roof. Sometimes they were elaborated, as may be seen, for instance, in the drawing from Hoorn (page 37). The dormer eventually became a much developed feature. In examples such as those shown from Leiden (page 39), where two of the houses are not ended by a gable, the main roof would be hipped back. A certain number of dwellings were built with one of the longest sides occupying the main frontage. The house at Hoorn (page 36) was so constructed. The floor-joists, carried through the walling, are exposed to view; they project beyond the face of the ground floor wall and support an overhanging upper storey. Similar examples occur at Vlissingen (Flushing), and there the joist-ends are carved with representations of small human heads, each of different design. Very noticeable, both in early and later work, is the great height of ground-floor rooms and passages. They not uncommonly measure from eleven to thirteen feet, or even more, from floor to ceiling. The windows, proportionate to the rooms, are extremely lofty. Over entrance doorways are fanlights of conspicuous size, which are occasionally nearly as large as the doors themselves. Some houses, with very high front rooms abutting on the street, have at the back two stories contained within this same height. The example from Woudrichem (page 38) is disposed in this way; the fore part of the hall, from which the drawing was made, together with the adjoining room are almost twice as lofty as the passage seen beyond; the stairs give access to the imposed intermediate floor. Heights of rooms gradually diminish upward from the ground, and the string-courses that externally mark the position of the floors, are consequently nearest together far up the walls and gables.
