Description

Lilac Cottage is a timber-framed and rendered cottage, likely dating from the 17th or early 18th century, extended to the rear in the 20th century. The front and right side elevations are rendered, the left side is weather boarded, and the pitched roof is covered with stone slate, featuring a central brick stack.

The cottage has a two-bay plan, originally comprising four rooms, with the central stack serving the front two rooms. The exterior displays an asymmetric pitched roof with a short, shallow slope to the front and a longer, steeper slope to the rear. 20th-century windows are present throughout, and a 20th-century boarded door is located on the south-west elevation. The rear extension is thought to be brick-built beneath the render.

Inside, the original rear wall of the cottage is visible within a cupboard beneath the modern staircase, showing stud timber framing with a straight downwards brace, infilled with brick. Elsewhere on the ground floor, the framing is concealed behind plaster and wallpaper, but sill and wall beams are largely visible, along with substantial transverse, stopped and chamfered bridging beams. Some ceiling joists have been replaced in the 20th century, while many earlier examples remain. One fireplace is a 20th-century replacement, the other possibly originating in the 17th century, but with later alterations. A 17th to early 18th century plank and baton door with contemporary hardware survives in the front left room.

On the first floor, the timber framing is generally well-preserved, with wall plates, tie beams and corner posts clearly visible behind the wallpaper. Some beams are attached to the wall plates with iron straps. Original 17th to early 18th century plank and baton doors with original hardware, including hinges, handles, and bolts, are retained in the front two bedrooms. The rear bedroom and bathroom, likely modern insertions located in the roof space, obscure part of the roof structure. The survival of tie beams at ceiling height suggests that the original roof structure remains above. Fireplaces on the first floor have been boarded up, tapering towards the roof.

Several outbuildings, including a garage, sheds, and a glass house, are located to the side and rear of Lilac Cottage. These are of mid to late 20th century construction and do not possess special interest.
