Description
The Round House is a former outbuilding that has been converted into a house, dating from the late 18th century. It is constructed of whitewashed brick and features a hipped slate roof with a central ridge stack at the front. The building is arranged around a nearly circular courtyard and is single-storey in height. On the north side, there is an angle bay to the left of center, and a bay that is set back at the left end. The front facade has six 4-centred arched windows adorned with "Gothick" decorative glazing bars. To the left, there is a 4-centred arched, planked door located behind an angled porch hood supported by two columns with fluted pilasters on the walls. A glazed extension is present at the right end, and a verandah with wooden posts encircles the interior.
