Description
The Conservators House is a toll-house dating to 1842, as indicated by a stone plaque in the north gable. It is constructed of gault brick with limestone dressings and has a plain tile roof with patterned ridge tiles. The building is two storeys high, with cellars, and is arranged as a T-plan gabled wing to the west of the main north-facing facade. It is designed in the Tudor style, featuring shaped gables with apex finials, and two large ridge stacks with recessed round arched panels and a stone cornice. The north facade has three first-floor windows with two and three lights, featuring mullioned and transomed casements. Below these are two similar three-light windows extending to the height of the plinth in the western wing. The main entrance is a plain, double pilastered stone architrave with a recessed four-panelled door and a patterned round headed arched fanlight. Internally, there is a committee room above barrel-vaulted cellars. The building was used by the Conservators of the River Cam, who were appointed following an Act of 1702 to make the River Cam more navigable from Clay-Hithe-Ferry to the Queen’s Mill.
