Rosebrook, 275 Drumrane Road, Dungiven, Co Londonderry, BT47 4NL

Rosebrook is a 2½ storey house of three bays with a centred doorway, gabled end with chimney stacks, and slated roof. A 2 storey back return with further single storey additions extend to the rear. The house is situated at Ardinarive, with a double avenue approach, one avenue having a pair of decorative metal gates, and enjoys a good setting with mature trees.

The entrance façade has good proportions overall. The centred doorway features a segmental arched opening with smooth rendered surround, lugged and finished with a keystone. The door itself is a hardwood panel door with sidelights and plain fanlight, all of recent date. Shallow single storey canted bays flank either side, topped with flat roofs and fitted with contemporary wooden windows. At first floor level are three vertical sliding sash windows with plaster surrounds matching the treatment of the doorway. The central window is round headed with five panes, three in the upper sash, each round headed. The other two windows are segmental headed with four panes each. The wall is finished with pebble dashing and has bold painted quoins. The pebble dashing is returned on each gable. The gables are largely windowless except for a pair of small square headed windows set high under the barges. The roof has been reslated in asbestos slates and the chimneys rebuilt in redbrick. There is no overhang to the long sides and only a meagre soffit to the barges. Gutters and downpipes are in PVC.

The rear of the house has been much altered. Two Velux-type windows have been inserted on the centre of the rear slope. Windows to the rear and back return have all been replaced, though natural slates have been retained on the 2 storey part and on a lean-to small roof which appears to be part of the earlier structure. The rear walls are smooth rendered and painted white. The northwest end appears to have been extended outwards. Farmyard buildings form a courtyard to the rear.

Historically, the site is shown on the Ordnance Survey map of 1832 as a rectangular block with back returns. The Ordnance Survey Memoirs describe it as "the residence of Mr James Douglas in Ardinarive consists of a long thatched cottage of 1-storey. It is much ornamented by belts of planting and a large and extremely fine orchard. The office houses belonging to the house are very ample and well suited to the extensive farming pursuits in which this gentleman is engaged". In the Griffiths Valuation of 1858, James Douglas was listed as lessor with Robert Taylor as occupant; the valuation was £14. At that time there was a miller's house, corn mill and kilns adjacent to the property. The Douglas family retained possession until the early 1920s when the Ross family acquired it. The present house is likely to have been built around 1850. It is possible that the outbuildings behind the house occupy the location of the single storey thatched house mentioned in the memoirs.

The character of secondary elements such as doors and windows is not sympathetic to the building's period, nor are materials such as asbestos slates, pebble dashing and rustic brick chimneys. The house is not considered to be of sufficient quality to merit listing.
