Wigmore House, 10 Ballydevitt Road, Coleraine, Co. Londonderry, BT51 4DR

Wigmore House is a symmetrical two-storey three-bay linen merchant's house built around 1810, located north of the River Bann east of Garvagh. The house is rectangular on plan with a lower two-storey rear return that incorporates vestiges of an earlier structure. Early twentieth-century modifications include a full-height canted bay to the east.

The roof is pie-ended with shallow hipped form, roll-moulded leaded ridges and hips, and rendered chimneystacks with simple moulded caps. Overhanging sheeted eaves support cast-iron ogee rainwater goods; the rear has simple projecting eaves, and the lower return has a torus moulded eaves course. The walling is ruled-and-lined smooth render, painted white, with a contrasting plinth course and stepped quoins. The ground floor of the main block has a painted masonry cill course.

Windows are 6/6 timber sashes without horns to the main block, and 2/2 horned sashes to the return except where otherwise stated. All windows have painted stone cills. The principal elevation faces south-east and is five windows wide at each floor. The central entrance comprises a replacement timber panelled door with beaded muntin, flanked by tall slender 2/2 sidelights and surmounted by a margin paned rectangular fanlight, all embraced by a pilastered surround with moulded masonry canopy supported on scrolled console brackets. Two low stone steps address the entrance.

The south-west elevation has two windows to each floor, vertically aligned. The rear elevation is abutted at its left side by the full-height return; the re-entrant angle contains a two-storey extension, which is further abutted at ground floor on the right by a single-storey lean-to addition. The exposed right bay has a single window to each floor. The extension has two small 1/1 sash windows at mid-level to the rear and a casement window to the addition. The return is further extended by a lower two-storey rear block of rendered coursed masonry construction, lit at each side by a series of windows to each floor and gable end, generally 2/2 but including a bi-partite sash to the north-east. A modern conservatory obscures the ground floor to the south-west, and a four-panelled timber door provides access at the north-east.

The north-east elevation comprises the main block, remodelled with a canted bay at centre and extended to the right by the north-east elevation of the full-height return, which is flush with it. The roof level is higher over the canted bay and return. The left bay of the main block has a window to the ground floor and two windows to the first floor, detailed as the facade. Thereafter, upper floor windows are segmental-headed, all in moulded architraves. The canted bay has a window to each floor at each facet. The return has two windows to each floor, except for a large twentieth-century insertion to the ground floor right, having a floating hood mould over it with a cartouche reading 'Wigmore / Built 1619 AD / Rebuilt 1806 AD / Restored 1993 AD / Vires Eundo Aquirit'. The lower range is flush with the return.

The house is set within large mature grounds, largely concealed from the road and sheltered by mature trees. A tree-lined avenue leads from Ballydevitt Road, bifurcating to access a gravel forecourt at the south-east and to stable blocks and rear entrance at the south-west. The site is accessed via an alcoved entrance comprising a pair of plain square gate piers supporting wrought-iron gates.

To the rear of the house is a range of single- and two-storey stables and outbuildings bounding a covered stableyard with a Belfast truss roof beneath a long lantern. The structures are a mix of nineteenth and twentieth-century construction, generally of brick (variegated brick to twentieth-century sections) with a rendered north-east elevation and hipped slate roofs throughout. The two-storey south-east range has been converted to disabled accommodation. The south-west elevation shows evidence of blocked openings. A range of timber sheeted doors with multi-light transoms and sash windows face the interior yard, which retains original timber and iron stall divisions.
