Seiont Manor (also known as Llwyn y Brain)

Seiont Manor, also known as Llwyn y Brain, is a largely 18th-century manor house, significantly extended in the mid-19th century to form a basic L-shaped plan. The original section is built of regularly coursed rubble stone blocks, with some traces of plaster remaining, stone sills and lintels, and has a hipped slate roof with a moulded wooden eaves cornice, two rendered ridge stacks, and a rooflight. A mid-19th century extension is constructed of rendered rubble stone. The front of the house features sash windows; the ground floor windows have 12 panes, while those on the first floor are smaller, with 16 panes. A shallow, central porch with a pediment contains six-panel double doors and a fanlight. A single-bay extension to the left has a 16-paned sash window on the first floor and a 12-paned sash window on the ground floor. A two-storey canted bay with a slate roof to the right return has six-paned sashes on the first floor and eight-paned sashes on the ground floor. The continuation of this return features sash windows similar to those on the front, a cross window on the first floor, a multi-paned window on the ground floor to the left of centre, and a late 19th-century oriel bay window on the first floor with a cross window to its right; all except the bay window have rendered dripstones. There are rendered ridge stacks to the left of centre and to the right. A flat-roofed projection below the right-hand cross window incorporates three sash windows. A projecting range to the rear of the main range has two horned sash windows on the first floor above a dilapidated lean-to conservatory, accessed by a French window. The rear wall features an 18-paned sash window, lighting the staircase, directly above a boarded door with a rectangular overlight. The long range on this side comprises six unequal bays, with original sash windows on the first floor, a replacement sash window, and a late 20th-century casement window on the ground floor. The ground floor also has two doorways.

The entrance hall, belonging to the early 19th-century section, has a plaster cornice with a ceiling rose and a pilastered elliptical archway leading to a dog-leg staircase. This staircase has a clustered newel post, a moulded handrail, a plain string, and two stick balusters to each tread. A room to the right of the entrance hall features a plaster cornice and panelled window shutters, including those to the bay window. A room to the left has a plaster cornice and an arched recess, originally containing a fireplace. Behind this is a smaller room with a Victorian marble fireplace, featuring tile insets depicting cavaliers and birds. The first floor also has plaster cornices, and panelled window shutters to the canted bay. The mid-19th-century addition has six-panel doors throughout and several good fireplaces, some with pilastered surrounds and console supports for the mantels, and cast-iron grates.
