either side by narrower versions, all three topped by transoms without any stone separator, rising from the upper of two stringcourses. Above them, in the apex, are two small recessed double-hung sash rising from a brownstone beltcourse, with the uppermost adjacent stones widening like a capital but flat and plain on the front. A wider brownstone course tops the windows. The gable has the same treatment as the north face. The south gable face is identical to the one on the north facade opposite in fenestration and treatment. On the west, the top gable pierces the roof above two shingle-cut stone courses. The three central recessed double-hung one-over-one sash rise from a stone cornice in which three pierced quatrefoils have been cut in the stone beneath the windowsills. Two joined engaged Corinthian columns divide the central window from those in its flanks, which are in turn flanked with single versions of the column. All three windows have decorative stonework above the lintel; above them is a course of vertical blocks and a cornice that forms a splayed-block arch above the central window. Its tympanum is blind, decorated with sunburst artwork similar to that found below on the front facade. That pattern also fills the gable apex; on the sides of the windows is a checkerboard pattern. Stone shields are affixed to either side; the one at the south has the city's coat of arms on it. The gable edge has the same decorative treatment as the other three. On the roof there are several small skylights next to the eastern and northern gable. A larger one is located higher on the east pitch of the northern gable, with two similarly-sized on the south face of the main gable east of the southern cross-gable. Just east of the southwestern chimney is an 18-cell solar cell array; a 27-cell array is on the east of the main gable just below the apex. Towers At the northeast corner is an engaged round tower with five bays. Fenestration on the first story is three windows with similar treatment to those on the neighboring north facade, except with two double windows on either side of a triple, and another double where the tower meets the east facade. Below are double-hung one-over-one sash, again like those on the north facade but without the bars, one beneath each double and two beneath the triple. On its third
