Seafield, 123 Killowen Road, Killowen, Rostrevor, Newry, Co Down, BT34 3AQ

Seafield is a one and a half storey, three bay double-pile house built between 1800 and 1819, located south-facing in a small mature garden with outhouses to the rear. Although of historical interest due to its connection with Lord Russell of Killowen (Lord Chief Justice of England), the building now retains few original features either internally or externally.

The roof is double pitched natural slate with concrete-coped verges and three large triangular gabled dormers rising from the eaves on the front pitch. Each dormer has a plain painted timber bargeboard and truncated timber finial. The rear pitch of the front block has a single skylight. Chimneys are set on each end gable, both in painted smooth render with a pair of square stacks set at 45 degrees, each with a single yellow clay pot. Rainwater goods are ogee cast-iron with painted metal downpipes. All walls are painted cement dash over a smooth painted chamfered cement basecourse.

The front door is set centrally within the facade and comprises a plastic door with double glazed sidelights and a segmental fanlight, all contained within a semi-elliptical headed opening with smooth render reveals. The facade wall insets to form an apron below each sidelight. All windows are plastic 1/1 top-hung casements with integrated 6/6 glazing bars and narrow painted concrete cills. The left bay contains one window and the right bay contains two. Dormer windows have cill levels running just below the eaves. The left gable has a single ground floor window on the left; the right gable is blank.

The rear pile abuts the left and middle bays of the back wall of the front block. Its exposed section of the main block is blank. The rear pile has a pitched, concrete-coped natural slate roof with chimneys matching those on the front block. Its walls match the main block. The rear pile's back wall is abutted on the left by a mono-pitched return with a natural slate roof and at the centre by a single storey flat-roofed kitchen extension. This wall has two top-hung plastic windows at eaves level with cills just above the extension roof. At ground floor level, to the right of the extension, is a smaller window matching those of the facade. To the left of the extension, at the head of a narrow passage with rear return, is a single plastic window. The left gable of this pile has a modern 6/6 window to each floor. The right gable is blank and is abutted by a small wet-dashed store with a flat concrete roof accessed from the rear kitchen. The walls of this return are dashed as the rest of the house. The end gable of the return has a small metal window, and its left cheek has a small four-paned window at ground floor level. The kitchen extension has a modern picture window on its right cheek and a similar window and door on its rear wall.

To the rear is a farmyard with whitewashed outbuildings. The front and side gardens are small and mature with decorative beds and shrubs. Garden access from the lane is via a wide wrought iron gate with cast iron posts. The garden also contains a plain granite sundial with bronze face and gnomon.

The house was once the residence of Lord Russell of Killowen. It was occupied in 1819 by Joseph Nicholson, a farmer. In 1838, it was described in a valuation as measuring 32 feet by 21 feet by 13 feet 6 inches high, with the owner given as James Small. In the same year, Arthur Russell, a Newry brewer, moved here with his family. Charles Russell, who later became Lord Killowen and Lord Chief Justice of England, was brought up in this house. The family returned to Newry in 1845. The house was described in an 1863 valuation as "a very neat little concern and good marine view."
