12 Bridge Street, Dromore, Co Down, BT25 1AN

12 Bridge Street is a two-bay, three-storey end-of-terrace commercial premises predating 1833, situated on the west side of Bridge Street to the north of the River Lagan in the centre of Dromore. It incorporates the upper floors of the neighbouring building at No. 10 Bridge Street, and the two properties are considered to have group value. The building has been restored in recent years and, while much of its original character survives, modern commercial interiors have largely replaced the original fabric. It is a good example of an urban commercial premises that developed incrementally over time, and its gable makes a prominent contribution to the streetscape in relation to the river.

The building has a rectangular plan with a shop-front at ground floor level, recessed beneath jettied upper floors, and a two-storey return to the rear (a later addition). The pitched roof is covered in natural slate with blue-black angled ridge tiles and rendered chimneystacks to the gables. Cast-iron half-round rainwater goods sit on a red-brick eaves course. The external walls are finished in painted ruled-and-lined render with straight quoins to the upper floors.

Windows throughout are 1-over-1 timber-framed sash with horns and painted projecting sills, except on the second floor where they are 2-over-2, and on the south elevation of the return where they are 3-over-3 with margin panes.

The principal elevation faces east. At ground floor level, the shop-front is recessed beneath the jettied upper storeys, which are each two windows wide and supported on three cast-iron columns — a distinctive and characterful feature of the building. The shop-front to the left has plate glass windows set on a chamfered stall riser, divided by timber partitions with trefoil detail to the squinches and timber-sheeted soffits. To the right of the shop-front is a replacement half-panelled timber entrance door. The entrance to the upper floors is at first-floor street level.

The south elevation is three storeys tall, with the ground floor sitting at river level. It has two windows at second-floor level and a window to the first and ground floor on the left. The west (rear) elevation has a 1-over-1 window at second-floor level on the left, and is abutted at ground-floor level by the two-storey return, which meets it at an angle. This return has a 1-over-1 window to the ground floor on the left and two multi-paned windows to its south elevation. The north gable abuts the neighbouring No. 10 Bridge Street.

The building sits directly north of the bridge over the River Lagan, forming the end of an early 19th-century terrace in Dromore town centre. To the north of the principal elevation, a timber-sheeted latch-gate gives access to a side alley leading to a rear yard, which is partially lawned and enclosed by a mature hedgerow.

The history of the building is well documented. It first appears on the first edition Ordnance Survey map of Dromore in 1833, and on the contemporary Townland Valuation plan of around the same date, which recorded it as having a rear return that extended to — and apparently into — the River Lagan, suggesting the building may originally have incorporated a mill or water wheel, though no trace of any such structure now exists. The Townland Valuations of around 1830 valued No. 12 at £13 6s. and recorded it as administered by a Mr. Adam Agnew of Rath House. By 1861, Griffith's Valuation recorded the property as occupied by Mr. Henry Graham, a surgeon, who leased it from a Mr. Thomas Stewart, with a value of £13. By 1867, ownership had passed to Hugh Stewart, also of Rath House, who served as Stamp Distributor for the local area.

In 1891, the property passed to George and William Preston, auctioneers, valuers and estate agents. Following William Preston's death in 1901, George Preston continued the business under the name George Preston and Son. George Preston remained the recorded occupant until his death in 1925, though the 1911 Census noted the building was unoccupied as a residence and was being used as an Auction Market — effectively an office for the auctioneering business. George Preston purchased both Nos. 10 and 12 Bridge Street in 1924, shortly before his death in 1925 whilst residing at Greenmount in the townland of Quilly.

The rear return that had originally extended into the River Lagan had been taken down by at least 1903, as confirmed by the third edition Ordnance Survey map. It is possible that this return was removed when the current Downshire Bridge was constructed in 1885, though the property's valuation remained unchanged at £13 until the end of the Annual Revisions in 1930, providing no definitive date for the alteration.

In 1969, the architectural historian C. E. B. Brett described Bridge Street as "rather a jumble, consisting largely of tall peeling stucco houses in a state of decrepitude but with one or two cheerful notes," and specifically noted No. 12 as a commercial premises with its "shop-front attractively set back behind simple iron columns." Brett also recorded that the entrance door formerly featured "curiously romantic mock-stained glass, portraying an angelic warrior on horseback," though this has since been removed.

Nos. 10 and 12 Bridge Street were listed in 1977 and have continued to be used as commercial premises. In 1998, the owners, Mr. and Mrs. W. Black, were awarded the Historic Buildings Council Award of Merit for the painstaking restoration of Nos. 10–12 Bridge Street.

The two-storey return to the rear of No. 12 does not appear on the 1973 Ordnance Survey map but can be partially seen in a survey image from 1975, suggesting it was either constructed between 1973 and 1975 or was present earlier but omitted from the map, possibly dating from the early 20th century.
