Number 29 And Walls Attached To South West

House, now offices, incorporating part of the precinct wall of St Mary's Abbey, Museum Gardens. The abbey remains from the early 14th century; the house itself dates from the late 18th century.

The terrace wall is built of magnesia limestone ashlar. The house is constructed of buff-brown brick in Flemish bond, with the rear in orange-brown brick in random bond. The ground floor features ashlar. The building has a timber doorcase and eaves cornice, with a slate roof topped with moulded stone kneelers and brick stacks.

The front elevation presents three storeys and three bays. The entrance features a 6-panel door with a radial glazed fanlight set within a doorcase of sunk-panel pilasters, a fluted impost band, and a dentilled open pediment supported on attenuated grooved consoles. The tympanum is enriched with composition garlands and ribbons. The windows are 16-pane sashes, except for two 12-pane sashes on the ground floor, all with painted stone sills and segmental brick arches of one course. Ground floor windows retain sunk-panel shutters. The right-hand window on both upper floors is blocked. A moulded modillioned eaves cornice runs across the front.

The garden front to the right displays two storeys and an attic. It includes a gabled bay with a shallow two-storey canted bay window. On the ground floor, a glazed and panelled door beneath a 6-pane overlight opens to the terrace garden, with flanking tall 8-pane sash windows. The first-floor window is tripartite with a 12-pane centre sash. The attic has a lunette window with a casement. The terrace garden wall features a high chamfered plinth beneath four blocked vertical slits. The right return contains a shoulder-headed doorway and a 2-light window with cinquefoiled heads, both blocked. An octagonal bowl font, much weathered, is positioned as a flower container in a blocked doorway.

The cellar contains a stone fireplace with a chamfered segmental arch and moulded mantelshelf. The ground floor entrance hall has a stone-flagged floor and a close string staircase with turned balusters and ramped-up handrail. The right room features a cupboard formed from a blocked passage and a shoulder-headed doorway to the former Almonry. Its fireplace has voluted jambs and a moulded dentilled shelf.

The first floor left room has a plain fireplace with a moulded dentilled cornice shelf and round-headed grate. The right room contains a fireplace with panelled pilaster jambs enclosing drops, palmette capitals, and a frieze enriched with garlands and urns, together with a panelled window recess. Both rooms have moulded plaster cornices.

On the second floor, the left room has a plain fireplace with a moulded shelf and hob grate with figures in the cheekpieces. The right room has a moulded plaster cornice and a plain fireplace with paterae and moulded and dentilled cornice shelf.

The attic features the top flight of the staircase with quatrefoil balusters and a door of raised and fielded panelling on H-L hinges at the head.

Attached to the western corner is a wall approximately 3.5 metres high and 20 metres long, returning to the south-east for approximately 2.5 metres and enclosing a raised terrace garden. This wall probably forms part of the Almonry of St Mary's Abbey.
