Probably C17 or C18, a three-unit farmhouse entered at the north side. Marked as Trewern-fawr on the Tithe Survey of 1839; owned by Frances Roberts and occupied by Richard Edwards with about 206 acres (83.43 hectares). In 1867 the house was doubled in size with a three-gabled south extension. At this time the original part was renovated and given a false west chimney. The house was replanned to face south, but is now again normally entered at the north side, through a later porch.


A large farmhouse in quasi-rubble masonry apart from a low rendered north porch which is probably in brick, all painted white; slate roof with tile ridges. The triple roof of the newer part is taller than that of the original house. Yellow brick end- and mid-chimneys.

Three-window north elevation of the original range with 12-pane horizontally sliding sash windows above and a single 16-pane sash window below; low modern lean-to porch at left.

The south, designed in the C19 to be the front, is the most significant elevation. This is in three gables with a datestone at the head of the central one, reading 'Rebuilt by / W[illiam] and M[ary] Morris / 1867' The fenestration of the left and centre gables is treated as a three-window composition, with 16-pane sash windows vertically aligned and a central semi-glazed main door. Stone sills, timber lintels. The ground storey window to the left is in a small canted bay. The doorway has a timber porch on brick footings with slate roof and gable facing and lattice panels. In the right gable are two similar upper windows set at a lower level with the mark of a walled up attic window above, and a small window below. One similar window in the east elevation, two in the west elevation. The sashes are generally hornless but several appear to have been restored with horns.


The hallway of the C19 entrance has straight stairs to one side.

Stairs in the central unit of the earlier (north) range are now secondary. Large lateral farmhouse chimney in the west unit, also chamfered main beams and rough joists. Boxed in oven believed to survive in the east unit.

Reasons for Listing

A three-unit vernacular farmhouse which has been enlarged in the C19 to a fine farmhouse of gentrified character, with gabled front - a noteable C19 form in this area.
