4 John Street, Omagh, Co. Tyrone, BT78 1DW

A detached three-bay two-storey Italianate former house, built around 1880, located on the east side of John Street in Omagh.

The building is well proportioned with a simple rectangular plan form facing west, typical of the Italianate style, though extensive interior alterations have compromised its architectural interest. It is not considered one of the best examples of the type, being of relatively late date.

The exterior is rendered over a plinth with chamfered quoins. The pitched natural slate roof features yellow brick chimneystacks with moulded cornice caps and octagonal terracotta chimneypots. The eaves are caved and bracketed. Gutters are half-round cast iron. The principal (west) elevation has a square-headed painted timber bolection six-panelled door with brass door furniture, painted timber lintel over console brackets, overlight and architrave with keyblock. Remaining bays each have a single window. Windows are painted timber with 1/1 sashes, featuring segmental arch heads with lugged moulded architraves and diamond-headed keyblocks over bracketed sills (ground floor windows are square headed).

The north gable has a variety of windows without architraves; two round-headed painted timber 2/2 sashes light the second floor apex. The rear (east) elevation is partly obscured by a modern projecting bay of no architectural interest. The south gable is abutted to the ground floor by an adjoining building, with the exposed section detailed as the north gable.

The building dates from around 1880 and first appears on the 1882 valuation town plan of Omagh, replacing a previous structure. Annual Revision records from 1895 list it as occupied by Mrs Treanor and leased from the Representatives of the Reverend Robert Hamilton, valued at £27. Valuers' notes indicate the construction cost was £500. The building comprised a two-storey house with an attic and basement (used as a coal house) constructed of rubble masonry and slated. By 1934, the property contained a kitchen, scullery, pantry and two rooms downstairs, with six bedrooms, a further room and bathroom and water closet upstairs, then occupied by Joseph Mulgrew with a value of £29. In 1949, Francis Mullan was the occupier and had built a shop in the adjacent area to the south (formerly his outbuildings), leased to Arthur Kelly as a chemist's shop.

The former house is situated on an elevated site on John Street, with a parking lot to the north and an adjoining building to the south. It lies within a conservation area and is now in office use.
