Description

Glan Ithon, including attached farm buildings

A farmstead comprising an L-plan rubble stone house to the south, a slightly lower brick and stone stable block attached to its north side, with a rubble stone barn and cart house at right angles, forming a U-plan block around a cobbled yard.

The main front of the house faces south, away from the yard. It has 2 storeys and 3 windows, beneath a slate roof with end stone stacks and projecting eaves. The central entrance features a Tuscan portico, panelled door and overlight. Windows are 3-light casements under tooled stone segmental heads. The left end is slate-hung, with the gable end displaying a 3-light casement window on 2 levels. In the rear wing, a dairy window has a central glazed light flanked by iron meshes. Facing the yard, the rear of the main range has 3-light windows similar to the front. The 2-window rear wing has openings under cambered lintels imitating voussoirs. It has a boarded door and overlight to the back kitchen, with small window to the left and 3-light window to the right. An added blockwork lean-to is at the right end. The upper storey contains 2-light and 3-light windows.

The stable and chaff room block has a brick elevation to the yard. At the left end is a segmental-headed passage doorway with boarded door. Further right are 2 boarded doors under overlights, each with a window to the left. The loft has a central loading door flanked by ventilation strips. The rear and right end of the stable block are rubble stone.

The barn has central large double threshing doors, with boarded 'lifts' at ground level serving as a barrier to small animals entering when the doors are open. There are 2 tiers of ventilation strips. The west gable end also has ventilation strips. The cart shed has a wide opening below a weatherboarded loft with window. In the east gable end are stone stairs up to the loft doorway. The north elevation of the barn is similar to the south. At the northwest angle, between barn and stable, is the lean-to roof of a covered pig yard.

Interior and Historical Character

The interior of the house is unaltered to an exceptional degree, illustrating the living and working patterns in a mid 19th-century farm. The building retains all its doors, fireplaces, architraves and skirtings. The ground floor consists of front and back kitchens, parlour, larder/dairy where butter was made, and a cellar for storage of dairy goods. Bedrooms occupy the first floor.

The front south door leads to a passage with a 19th-century wooden stair. To the left is the parlour, where the fireplace is flanked by elliptical-headed recesses with cupboards beneath. To the right of the passage is the front kitchen, which has a chamfered beam, a large fireplace with wooden surround and mantel, and a floor of large square stone flags. The back kitchen has a chamfered ceiling beam and flagged floor. At the north end is a large fireplace with iron range with wooden surround and mantel, incorporating a bread oven retaining its iron door and a boiler. At the south end is a secondary wooden servants' stair with cupboard beneath. Between the back kitchen and parlour is a pantry/dairy with fitted wooden shelves, a window with shutters to iron meshes, and a stone flagged floor. A doorway beneath the passage stairs leads to a cellar with stone stair beneath the parlour, fitted slate slab, and a window. The rooms on the upper floor all retain original boarded doors, architraves and other woodwork.

The barn range has king post roof trusses of oak and pine, with diagonal struts from tie-beams down to walls. On each side of the threshing floor are wooden platforms with boarding facing the threshing floor that has small doors for sheep. The cart house contains 2 re-used oak beams.
