Wallstreams, with Wallstreams Cottage

Wallstreams, with Wallstreams Cottage, is a farmhouse that has been converted into two dwellings. It likely dates from the early 17th century and has been altered over time. The building is constructed of thin sandstone rubble with quoins and features a slate roof. It has two bays and two storeys, with a storeyed outshut that projects on the north side.

The porch, which is two-and-a-half storeys high, aligns with a ridge chimney at the right end. It has a slightly-arched moulded doorway that is protected by a hoodmould with returned ends. This hoodmould is linked to a dripcourse that steps up and continues around the entire building to the left, stepping irregularly. On the first floor, there is a recessed three-light window with chamfered mullions, above which is a dripcourse that wraps around three sides. The gable features a small ogee-headed blind window with carved spandrels and a hoodmould with figured stops.

To the left of the porch, there is a short section of infilled masonry crossed by the dripcourse. The ground floor includes an inserted door to the outshut, a small square window with a hoodmould, and a double chamfered four-light window. On the first floor, there is a similar two-light window with a hoodmould and an inserted window. A coupled chimney is located on the ridge of this section.

The east gable has another small ogee-headed blind window under a hoodmould with conical stops. The south front features stepped dripcourses on both floors. The house part has a three-light window and a king mullioned window of three plus three lights on the ground floor, and similar windows of three and four plus three lights on the first floor. The eastern bay has a three-light window on each floor, all with deeply-recessed chamfered mullions in chamfered reveals.

Inside, the inner doorway in the porch has a slightly-arched moulded surround, a studded board door with strap hinges, and an original wooden lock on the inner side. Most internal partitions have been altered, and the building was formerly a baffle-entry, but the heck and bressummer have been removed. A former barn, which replaced the original third bay at the west end, is currently undergoing alteration and remodelling as of 1985 and is not included in this listing.
