Dogleap House, 91 Ballyquin Road, Limavady, Co Londonderry, BT49 9EY

Dogleap House, situated picturesquely on Ballyquin Road near Limavady, is a two-storey harled and painted country house that was substantially remodelled in the early twentieth century. Although not listed, it represents an interesting example of Arts and Crafts influence applied to an earlier structure.

The original building, shown on the 1831 Ordnance Survey map and recorded as "Roe Green" in the Ordnance Survey Memoirs of 1833–35, was constructed in 1828 by William Knox Esquire on the site of former office buildings. The memoirs noted it as "a good house" occupied at that time by William Pollock and owned by James Alexander Esquire. The property remained with the Alexander family through the nineteenth century. By the 1890s it was the home of Mrs Elizabeth Robertson, daughter of Jane Alexander and Edward Ritter, who became involved in a legal dispute with her brother John Ritter concerning water rights at Dogleap.

The house underwent significant architectural transformation when Miss Dorothy Robertson, who inherited the farm in 1924, commissioned renovations by architects Buchanan and Reid. Prior to this work, the building had comprised an eight-bay arrangement with a projecting porch and an end bay to the south, which was slightly taller than the remainder. A conservatory occupied the south gable.

The remodelled house now presents a late Arts and Crafts character. The main elevation faces south towards the Dogleap. This façade features a former gable converted with two projecting bays set at forty-five degrees to the main block, positioned at each corner. These bays are segmental at their ends with sandstone Tuscan columns that conceal window mullions on each floor. Half-timbered dormers crown the bays. The western elevation contains the entrance, marked by a projecting sand cement porch positioned near the front. North of this point, the character changes substantially: fenestration shifts from wide casement windows in the Arts and Crafts style to more traditionally proportioned Georgian twelve-pane sashes arranged regularly on each floor, and the roof level drops correspondingly.

The east elevation, perpendicular to the road entering Roe Valley Country Park, displays a main block with hipped roof and a central rectangular bay, from which projecting bays extend to the front. The rear features dormer projections added to some first-floor windows, with mullion arrangements adjusted to coordinate with the front styling. The ground level rises gradually to the north of the house, matched by dropping ridge lines that culminate in a small coach house at the northern end.

The west elevation, particularly the rear dormers, is considered less convincingly detailed than the south face and lacks the same architectural rigour, though it achieves the desired picturesque effect when viewed from a distance. The alterations have given the building an early twentieth-century character that, while substantially changing its original form, has compromised the architectural integrity that might otherwise have qualified it for listing.

The ornamental garden laid out formally to the south and west during the 1920s renovations remains substantially intact. The building has largely been unaltered since the Buchanan and Reid interventions. The current owner acquired the property in the early 1980s.
