A house may also have windows that are all the same size or have a variety of types and sizes that give emphasis to certain parts of the building. Historic buildings in the downtown commercial district are characterized by regularly spaced windows in their upper facade. These windows, in conjunction with their neighboring buildings, provide a pattern of openings in the wall of entire blocks. Windows in the front facade are often more decorative than the more utilitarian windows on side or rear elevations. Types of Windows Double-hung windows are the most common type of windows for most architectural styles.
Leaded windows contain patterned designs of colored glass.
They were popular during the Victorian period and early twentieth century. Composite windows are groupings of windows such as a double-hung window flanked by leaded windows or a set of similar windows. Dormer windows project from the roof of a house to provide light as well as increased floor and head space in a roof area. Decorative windows come in many shapes and sizes, such as circles or diamonds. Casement windows open on hinges rather than sliding within a frame, as double-hung windows do.
