The southern façade presents four bays of tall window openings dressed in elaborate plaster surrounds, pedimented at ground-floor level and entablatured above, where an entablature is the horizontal decorative band, drawn from classical architecture, that sits across the top of a window frame like a shallow cornice. A plaster string course, the projecting horizontal band that divides one storey from another, runs between floors and sharpens the whole composition into something considered and deliberate.

By 1842, when the Ordnance Survey recorded the area at six-inch scale, the house was already known as Woodlawn, suggesting it had acquired both a name and a settled identity since its construction in the late eighteenth century. The eastern end is where the building becomes most architecturally interesting. A two-bay bow projection anchors the front elevation and wraps around to the north face, where a tall pedimented stairway window lights what would have been the main staircase. The entrance is also on this eastern elevation, set within a pedimented plaster surround and flanked by sidelights folded into the door frame itself, a detail that manages to be both elegant and efficient with the available space. The square-hipped roof over the eastern bows is thought to be a later addition; the angles of its hips are carried outward from the curve of the bow on long timber brackets, a practical solution to the awkward geometry of roofing a curved projection that also gives the roofline an unexpectedly lively silhouette when seen at close quarters.
