Description

Tynohir is a large, three-unit house dating back to the 18th century, built of whitewashed rubble stone with a slate roof and tile cresting. It has a group value, representing an important contribution to the local heritage. The south-facing front features an external stone stack to the right of centre and a stone end stack to the left. Many of the windows are modern, from the mid to late 20th century, though some retain their original sash design. A late 19th-century porch, with a narrow gabled design, projects from the left of centre. The lower level of the porch is of blue brick, the upper level timber-boarded, with a timber-framed gable featuring curved struts and wide barge boards. It contains an inset doorway with a boarded door and small four-pane lights on either side. A large five-light top-hung window illuminates the first-floor chamber of the porch, while smaller two-light windows are positioned on the sides, also top-hung. To the left of the porch is a canted bay window constructed of rubble stone with a hipped roof, featuring small-pane, top-hung wooden windows. To the right of the porch, rebuilding in brick is evident in the central unit, incorporating a top-hung window under a large slate lintel and a shallow, 20th-century small-pane window in the upper storey. A twelve-pane horned sash window sits to the right of the lateral stack, also beneath a large slate lintel. The east gable end displays sixteen-pane horned sashes under slate lintels, with a central ground floor window and two upper floor windows. The west gable end has two narrow top-hung windows in the upper storey, above which is a false collar beam supported by large corbels. The rear of the house is characterized by plain-glazed 20th-century casements and top-hung windows. A lean-to staircase projection extends from the left side of the rear, projecting into the hall and featuring a top-hung window and a two-light window with a slate lintel to its right. A boarded door is located to the right of centre on the rear. A pentice, roofed with slate and supported by narrow timber posts with decorative braces, runs from the staircase projection to the service wing at the right end, with three three-light, shallow windows with slate lintels above it. The wing at right angles is a single-storey service block, built of whitewashed rubble stone with a slate roof and a stone end stack to the right. It originally had a central doorway, now blocked with stone, replaced by a boarded door to the left end, underneath the pentice. The rear of this wing has two two-light, 20th-century windows.

The front entrance opens directly into the former service rooms, now used as a kitchen, bathroom, and stair-hall. An open-well staircase features decorative balusters and carved newel posts with oval finials. The reception rooms have been plastered, largely concealing original details. The hall, with a lateral fireplace and a rear staircase, was originally on the right. The parlour, located to the left, retains a ceiling with deeply chamfered spine-beams with cut stops. The upper storey walls are plastered, but parts of the tie-beam trusses and purlins are visible.
