Marden House Centre

Marden House Centre is a former canal building located at the end of the Calne branch of the Wiltshire and Berkshire Canal, likely once used by the wharfinger. The building dates from the 18th century and around 1830. The central block, which projects, is made of ashlar, while the rest of the structure is built from coursed limestone rubble. The side wings have steep-pitched roofs, with a pantile roof at the rear and a slate roof on the front slope of the left wing, which also features a small square stack on the left gable end. The right wing has a pantile roof, and the main block has a slate roof with a truncated stone stack on the right.

The building has a symmetrical three-window central block that was integrated into the front of the former structure, resulting in a double-pitched, double-depth plan. It stands two storeys tall with two windows in each wing, giving an overall seven-window range. The 20th-century double doors are topped by a 19th-century overlight with four panes, flanked by 19th-century flat arches with keystones above plate-glass sash windows that have margin panes; the ground-floor windows are wider. A cornice below the parapet features a fluted frieze.

To the left, the 18th-century block has a similar first-floor window, an ashlar platband, a small 19th-century plate-glass window on the ground floor to the left, and a 20th-century door to the right. The right wing, likely older, is constructed from softer limestone rubble and has two 19th-century horned 2/2-pane sash windows on the first floor, a platband above a 20th-century door and porch to the right, and a 20th-century plate-glass window at the far right. A small 18th-century window is located at the apex of the gable end of the right return.

Inside, the ground floor of the central block retains panelled window shutters and reveals around the door. In 1914, the first floor was removed, and the roof's timber trusses were replaced with metal to create a scout hall. The building is included for its group value and historical interest.
