Description

Lower Tresenny Farmhouse is a complex building, dating from the late 16th century to the early 17th century, with later alterations. The farmhouse is constructed of painted rubble stone with a slate roof and brick stacks. The north front faces the road and is divided into three sections. To the left is the gable of an early 17th-century wing, and to the right, the gable of a late 16th-century parlour wing. The parlour wing's gable features two 20th-century six-pane fixed windows in segmental arched openings and a 17th-century six-pane casement below. The main part of the house, set back to the left, is two stories high with a lower roofline. The ground floor on the right has a round-arched entrance doorway with a projecting keystone, a 20th-century transom with cambered stone voussoirs, and a 19th-century 2+2 pane casement on the first floor. A change in the building line is visible at this point. To the left of this section, the eaves are lower and feature 2+2 pane casements on the ground floor. The left-hand gable has a sculptured stone mask under a dripstone in the gablehead, and a six-light diamond mullion window on the first floor. The west front of the parlour wing, which faces the farmyard, has a former centre entrance doorway that has been blocked. Both first-floor windows have deep timber lintels and thin stone sills and are 20th-century replacements. On the ground floor to the left of the parlour wing is an early 19th-century bay window with canted sides and a centre metal casement. The garden elevation displays the gable of the late 16th-century house on the left, featuring a 20th-century six-pane window to the attic, a 20th-century transom on the first floor, a boarded door, and a three-light diamond mullion window in a chamfered frame on the ground floor. The back of the main house has a 20th-century transom on the first floor and a 19th-century 6+6 pane casement on the ground floor. The early 17th-century wing has two boarded doors, two 20th-century windows, and a 17th-century three-light diamond mullion with wooden stanchions. The east elevation is partly derelict but retains eight-light mullions on the first and ground floors of the gable. Further to the right, there’s a three-light mullion in the middle wall and a four-light mullion with iron stanchions on the ground floor.

The original west entry to the late 16th-century parlour wing is now blocked, and it opened into a stone-flagged cross passage. To the left of the passage was the parlour and to the right, partitioned service rooms. Mortices in the headbeams indicate the positions of former post-and-panel partitions. A Tudor arched doorway leads to the pantry. The service rooms have chamfered beams with hollow and fillet ('Wern-hir') stops and joists with a roll moulding at the angles. The parlour features ornate, converging ceiling beams with centre hollows and quarter rounds, and a massive Tudor arched wooden lintel over the fireplace and a blocked fireplace stair to the right. The first-floor best chamber has similar ornate ceiling beams to the parlour; elsewhere, there are chamfered beams with 'Wern-hir' stops. The attic stair has a 16th-century plank and batten door. The attic itself is divided into four bays, with roof trusses originally having collars. A post-and-panel partition has been repositioned against the living room wall. The east end of the house has been heavily altered. The downstairs kitchen has chamfered beams with straight-cut stops. A Tudor arched doorway is located on the floor above. A derelict and floorless two-story workshop does not have a chimney.
