Former Devonport Market House

The Former Devonport Market House is a market hall that has been converted into a store. It was built in 1852 by St Aubyn and showcases an Italianate style. The structure is made of squared, snecked limestone with granite dressings and features a cast-iron and mineral felt roof. It has a rectangular plan and includes a northwest clock tower.

On the exterior, the building stands two storeys high and has a three-bay range. The ground floor features three round-arched doorways, with the right and middle doorways blocked, while the left has double doors. These doorways are linked by an impost band and cornice. Above, there are three upper iron-framed fully-glazed gables that contain an arcade of round-arched windows beneath a panelled band and moulded gables with round-arched lights and glazing bars arranged in a 3:6:3 pattern. The corner tower is set diagonally and has a battered rusticated ashlar base with open round arches and a cornice. The tower features rusticated quoins and a cornice that rises over clock faces on each side, along with an open belfry that has keyed round arches and balustrades, a modillion cornice, and a swept leaded roof topped with a weather vane. The right-hand return wall has a stone finish with 1:3 upper windows, while the left-hand side has a brick ground floor with two round-arched doorways. The rear of the building has been altered, featuring a rubble ground floor with a corrugated iron lean-to roof and incomplete sides, beneath a corrugated iron screen and iron gables similar to the front.

Inside, the building contains a notable cast-iron double Imperial stair at the rear that rises to a landing and then turns to the sides, leading to a cast-iron gallery with lattice railings on three sides of the hall. This gallery is supported by round columns with palm leaf capitals and features three parallel iron-trussed roofs. The building is particularly recognized for the architectural interest of its tower and the quality of its internal ironwork and glazing.
