12 New Road, Donaghadee, County Down, BT21 0DR

12 New Road is a large, two and a half storey Edwardian free style terrace house, built around 1905 as part of a distinctive asymmetric block of three dwellings designed by James A. Hanna. The building forms the eastern end of this terrace, which sits on the south side of New Road, north of Donaghadee town centre.

The terrace is characteristic of Hanna's work, displaying a mixture of canted bays with scalloped parapets, half dormer gables, and prominent chimneys, executed in brick, stone and roughcast. No. 12 is largely identical to its neighbour No. 14 to the west, both following ultimately traditional plan terrace houses dressed in Edwardian eclectic façades, while No. 16 at the west end is slightly larger with a freer plan.

The asymmetric front (north) façade features a glazed and panelled front door with a simple four pane fanlight above it, positioned to the right on the ground floor. To the left is a two storey canted flat roofed bay with a decorative scalloped parapet. Each face of the bay at ground and first floors has a simple casement window with six panes; those at first floor are shorter in height. Both windows are dressed with sandstone surrounds. Centred on the bay at attic level is a large gabled half-dormer with a three-pane casement window, its dormer wall edges battered and the gable finished with a moulded coping.

The east gable has two casement windows at ground floor level on its left side: the far left is six-pane while the right-hand one is narrower with three panes. At first floor on the left side is a wide nine-pane casement window. The second floor, set within the gable, has two evenly spaced plain casement windows on either side. A slightly projecting brick chimney breast rises vertically through the ground and first floors, then offsets left before rising to the gable chimneystack.

The rear south elevation has a six-pane casement window to the ground floor on its right side, while the left side is obscured by a two storey gabled return. The western face of the return is blank, while its gabled south face has a small recently added brick-faced lean-to porch to the left at ground floor level. A large, modern single storey flat-roofed extension is attached to the south face of the return, somewhat lower in height than the lean-to.

The return's gabled eastern face has a wide modern window at ground floor left, and a relatively wide two over two sash window to the right. At first floor on the right side are three narrow sash windows (two over two, two over two, and one over one, reading left to right). The centre of the first floor of the return's gabled face has a two over two sash window.

A tall chimneystack rises from the middle of the eaves of the south façade. A small Velux window is positioned at the centre of the main rear roof.

The return, rear elevation, and first floor of the north façade are all finished in roughcast render. The ground floor of the north and east façades are faced in brick. The main and return roofs are covered with natural slate. Cast iron rainwater goods are present throughout.
