42 Quarterland Road, Rathgorman, Killinchy, Co. Down, BT23 6TX

42 Quarterland Road is a small, single-storey vernacular house of probable pre-1834 origin with a thatched roof. It stands on the south shore of a sheltered bay on the east side of Quarterland Road, approximately two miles south-east of Killinchy, largely cut off from Strangford Lough by the Ringhaddy peninsula to the east.

The original house has been substantially extended at the rear in recent times with a large modern single-storey block, though the front façade appears to have witnessed no significant external alteration. The front (north) façade features a partly glazed door positioned to the centre left, flanked by a four-pane casement window to the left and two identical windows to the right. These windows may have been enlarged at some stage. Both the east and west gables are blank. The rear façade retains two small windows with modern multi-pane frames to the left, with a glazed door to their right. The large modern extension stretches to the west of the original house, roughly occupying the site where a gabled outbuilding or dwelling stood when the property was surveyed in September 1978. This extension has a part gabled and part hipped roof.

The original house is finished in roughcast and painted. The roof is gabled and thatched with rendered parapets and rendered chimney stacks to each gable, and a further similar chimney stack to the west of centre on the ridge.

To the east of the original house stands a converted outbuilding now serving as a recreational room and shed. To the north, near the rocky shoreline, is a low rendered wall with a simply decorated wrought iron gate, which originally stood between the east gable and the adjacent outbuilding.

A building matching the size of the original section appears on the 1834 Ordnance Survey map but was not noted in contemporary valuation records. It is recorded in the second valuation of 1861, with occupant John Moore, lessor Lord Dufferin, and rateable value of £4.
