The Umbra, 645 Seacoast Road, Benone, Limavady, Co Londonderry, BT49 0LH

The Umbra is a mid-Victorian seaside residence located on rising ground at the base of Binevenagh, overlooking Seacoast Road with views north-west towards the sea across sandhills. Built around 1844 by Henry Tyler through the enlargement of two existing cottages, it represents a rare example of a well-preserved shore house in the Magilligan region and is Grade B1 listed.

The house is constructed of coursed basalt with a slate roof and comprises two storeys arranged in five bays with a one-bay extension and greenhouse at opposite gables. It has a notably shallow plan. Three chimneys sit at the roof apex—one centrally placed and two at the former gables.

The principal facade is formal and urbane, raising the black stone vernacular of the region to a more considered composition. The centrally placed panelled entrance door has a pitched roof with decorated barge and is approached by four steps. Directly above is a centrally positioned broken casement window with round head to frames measuring approximately 1100 by 1500 millimetres. Similar casement windows without round heads flank this entrance at both ground and first-floor levels. The end bays each contain a bay window surmounted at first-floor level by a tripartite window with stepped granite lintel and brick quoins. Each end bay is topped by a gable with decorative barge. The joinery work on the bay windows is finely executed. The north-east bay is rectangular while the south-west bay is canted.

A two-storey extension to the north-east has a matching first-floor window. At the south-west gable, a Victorian greenhouse lean-to abuts the building. This structure features fine cast iron mullions that sweep down from the wall and curve into an iron trough, though it is now in need of restoration. The gables are windowless; the south-west gable is rendered in sand-cement with a door at base accessing the greenhouse, while the north-east gable has a blocked high-level window and a ground-floor door, both with decorated barges.

The rear elevation is coursed basalt with Georgian sash windows of irregular sizes and intervals, finished with brick lintels. Two bays project from the rear: one from a first-floor bedroom at the south-west end, and one with clear glass roof and frosted glass panes from the living room at the north-east end. Behind the house, a jumbled collection of brick and stone outhouses sit hard into the slope and align with the main structure.

The interior remains remarkably unaltered, though the building is now in need of maintenance. It has retained its original character under the care of its long-standing residents, notably Lady MacDonald Tyler, who died in the mid-1980s aged 90 and was the last to permanently reside there. She refused to allow modernisation of the building. The house has remained in the Tyler family throughout its history, and the current owner's daughter returns regularly from England with her family.

The setting and gardens are of particular note. The Ordnance Survey Memoirs of 1835 record that three small cottages existed at the Umbra townland at the foot of Binevenagh, built by the late Dr Tyler and Messrs Moody and Cather of Newtown Limavady. A notable wild garden climbs the cliffs behind the house, with ornamental species still visible, and if restored could be of international interest due to the unique flora of the region documented in the Ordnance Survey Memoirs. The Heritage Gardens Inventory divides the house and surrounding area into ten zones: the house itself; the conservatory; fruit and vegetable garden; former summer house; mountain garden; south-west orchard; planted trees on the mountain; low-level forest; sand dunes (now the Umbra wildlife sanctuary); and the gardener's cottage at 730 Seacoast Road. Much of this surrounding land is now the property of the neighbouring house 'Ferns'.

An extension was added at the turn of the twentieth century. The house forms an imposing group with its neighbour, together raising the architectural quality of this rare coastal setting.
