Description

No. 17 Landport Terrace is a terraced house, now used as offices, built around 1840. The building is finished in stucco and features a Welsh slate mansard roof with fish scale patterned lead on the lower slopes, along with a rendered stack on the rear pitch.

The house has three storeys, a basement, and an attic, with one wide bay. The ground floor is rusticated. Above, the first floor is flanked by tapered Ionic pilasters that are fluted on the first floor and panelled on the second. To the right, there are eight stone steps with attached railings leading to a projecting porch. This porch has an open front with a voussoired segmental stuccoed arch, a vermiculated keystone, and a drip-stone. Behind the front is a recessed three-panelled door with an overlight, where the upper two panes are glazed and the lower is a moulded panel.

On the left side, there is a three-storey canted bay with a wide central sash and narrow flanking sashes, each set under a parabolic arch with a flat soffit, incised voussoirs, a vermiculated keystone, segmental dripstones, a moulded sill, and a panelled apron. A moulded sillband runs across the first floor, supported by three shaped brackets flanking the bay. The first floor features a dentilled sillband, a central sash, and narrow flanking sashes, each with a fixed overlight and set under a flat arch with a keystone. The second floor also has a dentilled sillband, a central sash, and narrow flanking sashes, each set under a segmental arch, with a panelled apron, dentilled cornice, and a low pitch slate hipped roof. At the centre, there is a circular lead-covered dormer with a moulded architrave, a moulded bracketed cap, and a moulded horizontal sill. The interior has not been inspected.
