Diocletian window in gable apex. Left of the gable, paired narrow small-paned sashes on each floor and a 4-light dormer within the roof, offset to right.

Left hand gable return (SE elevation): Distinctive form given by dip of roof low over ground floor of garden front to form asymmetrical gable; fenestration forming a balanced composition, with tripartite small-paned oriel window in gable apex, mullioned and transomed small-pane sashes either side at first floor, with similar window aligned to ground floor right. Five-sided bay window offset to left, with small-paned sashes, and similar window wrappping the left hand angle, forming part of a glazed verandah.

Rear elevation: Dominated by advanced central gable anchored by very tall right hand stack. This gable has full-height canted bay window with small-paned sashes, leaded apron swept up from the wider (3-light) lower window, to the narrower (2-light) upper window. Upper window similarly detailed, and flanked by small side lights aligned with the upper panes of its sashes; Diocletian window in apex. To right of gable, the roof sweeps down over the verandah (with modern glazed infill); to its left, are original small-paned sash window to first floor, other windows renewed.
