Drenagh House, 15 Dowland Road, Fruithill, Limavady, Co Londonderry, BT49 0HP

Drenagh House is a large two-storey house of ashlar sandstone with a slated roof and lead ridges and hips, situated at Fruithill near Limavady in County Londonderry. The house displays refined Neoclassical architectural detailing, though built in a manner typical of early 19th-century Irish country houses.

The principal south-east façade is dominated by a single-storey tetrastyle Ionic portico with double columns flanking the central entrance, supporting an entablature with detailed cornice surmounted by a balustrade returned to the main wall plane. The columns are unfluted and taper gracefully to a necking decorated with classical motifs. Pilasters with Ionic capitals and matching necking are reflected on the wall surface flanking the portico. The entrance door features a semi-circular fanlight with narrow round-headed windows to either side. Two string courses run horizontally across the principal façades: one aligns with the sill line of the upper windows; the other continues the line of the portico cornice. Ground-floor windows are restrained Georgian compositions with chamfered reveals, while first-floor windows have architraves with curved lugged bottoms and thin cornices above. The wall terminates in a full entablature of simple design, with the cornice echoing the portico details. Open balustrading rises above the cornice across four bays, with a solid central infill.

A lower two-storey six-bay wing extends to the north-east, similarly faced in sandstone with smaller 12-pane windows. The south-west façade contains six bays; the central two form a positive breakfront marked by a distyle arrangement of Roman Doric pilasters supporting an unadorned pediment. The balustrading continues around this face, interrupting at the pediment.

The north-west façade is more restrained in treatment, comprising five bays modelled only by two canted bays on either side of a ground-floor French window with an elliptical fanlight that opens onto an extensive flat lawn. A lengthy balustraded wall bounds the lawn, with a ha-ha beyond separating it from the rolling demesne landscape.

The north-east return incorporates a lower wing containing offices and a land steward's house. Its north-east face features a centrally placed breakfront gateway with an elliptical arch, above which rises a three-storey section terminated by a plain pediment containing a clock face. This façade is seven bays wide, faced in pink ashlar sandstone with storey heights defined by plain and moulded string-courses. Through the gateway lies a paved courtyard surrounded by more utilitarian office buildings, three walls of which are finished in rubble stonework with brick-trimmed openings, while the wall adjacent to the main house has a smooth rendered and painted finish. Outside steps in the courtyard lead down to a basement extending beneath one-third of the main house, marked by semi-circular depressions serving basement windows.

The house is designed by Lanyon and demonstrates the progression of his Neo-classical vocabulary across its various facades, from the disciplined and successful main elevation to the more utilitarian treatment of service areas.
