Crookedstone, 1 Ballyarnott Road, Aldergrove, Crumlin, Antrim, Co Antrim, BT29 4DT

Crookedstone is a two-storey thatched and harled house located in rural County Antrim, standing at the end of a long private lane and hidden from public view. The building dates to 1699, as shown by a datestone on the porch.

The main entrance faces south-west. The entrance elevation is five openings wide, with two windows to each side of an off-centre porch on both floors. Walls are rendered with wet dash painted white, with a battered profile at the base and a black-painted plinth. A projecting plain eaves course runs along the wall. The roof is thatched between gable upstands with painted concrete copings; the ridge and eaves are protected by chicken wire, with three rows of scallops at the ridge and one row at the eaves. Three rendered chimneys are positioned—one on each gable and one in an intermediate position.

Ground floor windows on the entrance elevation are rectangular timber sliding sashes, vertically hung, with 6 over 9 panes and horns, set in exposed sash boxes within smooth rendered reveals with recessed sills. First floor windows are rectangular timber 18-pane side-hung casements in exposed timber frames, set in similar reveals.

The porch is rectangular with rendered walls that are flush and unbattered. It has a lean-to roof of red tiles, a PVC gutter and downpipe returning to the left-hand side, and a rectangular timber 6-panel door. A datestone reading 1699 is painted on the wall above the porch.

The right-hand gable is two-storey and rendered like the entrance front. The ground floor contains a semi-circular arched neo-Georgian style timber fixed light with 16 panes and a radial fan set in smooth rendered reveals. The first floor has two rectangular timber 12-pane side-hung casements in exposed frames with similar reveals.

The rear elevation is two-storey with walls, roof, and gable copings matching the entrance front, but without the projecting eaves course. A single-storey flat-roofed porch projects from the right-hand side. The first floor has one sashed window matching the ground floor design of the entrance front. The ground floor has three windows: a tall narrow 10-pane casement on the left; coupled two-light 8-pane casements in the centre; and a 12-pane casement on the right, all with exposed frames set in smooth reveals. The porch has flush rendered walls and a smooth rendered parapet above a lower corrugated perspex roof forming an open shelter with steel posts, timber beams, and timber fascia.

The left-hand gable is rendered above a single-storey link block connecting to a new house. This new house is two-storey and gabled with a red tiled roof. A single-storey flat-roofed link block adjoins it. Walls are rendered with roughcast, and windows are mainly rectangular timber sliding sashes with pane sizes similar to the original house.

An L-shaped gabled and tiled extension projects from one end of the original building.

The house stands in its own grounds at the end of a private lane. A tarmac forecourt area fronts the house, enclosed by a low wall of large boulders. A single-storey rendered and slated garage or outbuilding faces the house across the forecourt. A detached rubble stone outbuilding with an asbestos slated roof stands to the south side, with a single circular conically capped whitened rubble stone gate pier adjacent. An expansive lawn extends to the front of the house. A tarmac area to the rear provides access to gardens beyond. Barns and other outbuildings stand well to the south. Flower beds run along the base of the front elevation and the right-hand gable. A pair of tapering Tardree granite bollards stand immediately outside the front porch but are not fixed in position.
