Outbuilding, East Lodge, Mount Stuart House

East Lodge at Mount Stuart House is a late 19th century, asymmetrical, two-storey, two-bay house designed in the Old English style. It features half-timbering and has a single-storey, single-bay pitched addition on the outer left. The exterior is finished with whitewashed harl, and includes a raised, painted string course and painted margins. The eaves are overhanging and supported by timber brackets, with dormers that break the eaves line. A three-bay arcaded verandah is located at the front, and there is a single-storey, rectangular-plan outbuilding to the northwest, which is partly built of whitewashed brick.

On the southwest (entrance) elevation, there is a centrally placed two-leaf timber panelled door at ground level. The pitched verandah extends to the outer right and is supported by red brick plinths beneath stop-chamfered square-plan timber shafts, timber brackets, kingposts, and braces. To the left of the entrance, there is a single window at ground level and a dormer above. The single bay addition to the outer left has a single window centered in it.

The southeast (side) elevation features four-light canted windows at both ground and first floors in an advanced, gabled bay to the left of center. There is a single-storey pitched verandah to the outer left and single windows at both floors in a recessed bay to the outer right. The windows predominantly have leaded timber casement glazing. The roof is covered with red clay tiles, some of which have fish-scale detailing, and is adorned with decorative terracotta ridge-tiling and finialed gableheads. The ridge and apex stacks are coped, and there are various circular cans.

The interior was not seen in 1996. The outbuilding on the southeast (side) elevation has a timber entrance in the outer right bay and a single window in the flanking bay to the left, with a graded grey slate piend roof.
