The building lies close to the main Shrewsbury to Welshpool Road within the township of Trewern.


Largely sub-medieval timber-framed farmhouse with painted brick infilling and slate roof. Plan consists of a 1½ storey main range of the later C14 or C15, set parallel to the road and comprising two unequal bays, and an added mid-late C16 2-bay cross wing at the E end projecting to the S. The early range, of heavy vertical storey-high studs, was probably originally an open hall, floored over with the introduction of a stack in the late C16 - C17, possibly the same time that the cross wing was built.
The RCAHM (Wales) have recorded a date of 1610.

Entrance through a depressed headed opening on S front within a C19 small gabled porch. Timber windows with modern diamond leaded glazing and two C19 two-light gabled dormers with shaped barge boards. W gable has exposed frame and roof truss with single purlin, probably originally covered this end by a further bay, now lost. Cross wing has attic, jettied at the front, and shaped bargeboards. Detailed investigation suggests the wing is of the same workmanship as the early end of Trewern Hall.
Main C17 stack with four cylindrical flues, and brick ribs.


Kitchen, at W end, has renewed fire lintel on gritstone piers, with two C13 male and female heads, reputedly from Strata Marcella Abbey. Very deeply chamfered spine beam and chamfered and stopped joints. Some panelled C18 doors imported from Lancashire. Roof said to have smoke blackened timbers above the ceiling. Cross wing, originally without windows to the farmyard, of 2 unequal bays separated by a framed partition containing a shaped doorhead, apparently moved along when the large stack was inserted. Fire lintel on stone piers, the chamfer continuous. Deeply chamfered cross ceiling beams. Originally a salting room/dairy at NE corner. C17 dado panelling with narrow reeded upper panel.
