110 Irish Street, Downpatrick, County Down, BT30 6BT

110 Irish Street is a fine three-storey Georgian terrace townhouse of circa 1760, situated on the east side of the south end of Irish Street in Downpatrick. The building now functions as flats following subdivision in the 1970s.

The west front is asymmetrical. At the centre of the high ground floor is a timber-panelled door with a plain semicircular fanlight, surmounted by a broken pediment supported on console brackets. The doorway surround is now covered with Tyrolean finish. The door sits at the head of a double flight of stone steps with plain wrought iron railings. To the left of the door are two sash windows with Georgian panes in a 6/6 configuration. To the right is a single plain sash window. The first floor contains four evenly spaced sash windows, similar to those on the ground floor left but slightly shorter. The second floor has four 3/3 sash windows, positioned as before but considerably shorter. The windows to the first and second floors are aligned vertically, though the two sashes to the left of the ground floor sit slightly out of line with those above. The front façade is finished in unpainted lined render with moulded in-out quoins along the left-hand edge. The eaves course projects slightly. The basement windows to the front have been blocked. The north gable is blank and rendered as the front.

The east rear façade has two two-storey returns. The southern return is a lean-to, leaning against the return of its neighbour. The central return is flat-roofed. The east rear of the original building is largely obscured by these returns, but to the left of the flat-roofed return, the first and second floors are exposed though blank. The second floor has three small window openings with modern timber frames. The left side of this façade originally had a full-height recess, now mostly obscured by the later returns except at the top. The south face of the flat-roofed return has one first-floor window opening with a modern timber frame and a blocked door opening at ground floor. The east face of this return has two small ground-floor window openings and one similar opening to the first floor, all with modern timber frames. The east face of the lean-to return has a wide ground-floor window opening with a modern timber frame and a similar window to the first floor. The main roof is covered with natural slate; the flat roof appears covered with bituminous felt. The rear elevations are finished with lined render. On either side of the main roof ridge are chimneysstacks. The northern stack was rendered, resulting in loss of detail, and has three plain pots. The southern stack is brick, appears to have been reduced in height, and has no pots. Rainwater goods appear to be mainly cast iron.

The site is shown as occupied on the town plan of 1708 and all subsequent plans. Based on the front façade, particularly the pedimented doorcase, the present building probably dates from circa 1760 or slightly later. In the 1838 valuation returns, the resident was recorded as Mrs Nevin, with the house possessing a rateable value of £24.
