Description
11 St James Crescent is a terrace of four houses, now used as offices, located on the convex curve of St James Crescent. The arrangement features a central house with five windows, flanked by two houses with three windows each on the left and one three-window house on the right. The exterior is finished in stucco, with band strips at the sill levels of the first and second floors. The second-floor windows are set in shallow moulded surrounds with keystones, while the first-floor windows have stucco bracketed segmental pediments above segmental headed windows. The terrace primarily features horned sash glazing, although some inappropriate modern materials have replaced the original glazing, particularly in No 10. The roofs are slate, and there are large red brick chimneys.
No 8, the leftmost house with three windows, has two dormers and a left bay of two windows that is slightly advanced. It features Doric pilasters at the ends, with the left pilaster clad in artificial slate, which also covers the gable end of the terrace. The paired windows on the second and first floors are complemented by a splayed bay window on the ground floor to the left, and the entrance doorway, which includes an overlight, is situated under an open porch supported by pillars.
No 9, although it lacks the advanced bay, is a mirror image of No 8 but has a rebuilt ground floor bay. No 10, the five-window house, also has Doric pilasters at the ends and three dormers. Its ground floor features a central doorway with a stucco architrave and a panelled door, with glazing throughout.
No 11, the rightmost house with three windows, has three dormers; two windows on the right are slightly offset, and the ground floor features an entrance doorway with an overlight under an open porch with pillars. To the left, there is a splayed bay window with brackets at the angles, although it has modern plastic glazing.
