280 Tennent Street, Edenderry Gardens, Belfast, Co Antrim, BT13 3GG

280 Tennent Street is a three-storey, single-bay terraced house of brick construction dating from 1907–09, located on the western side of Tennent Street in the Shankill area of Belfast. It forms part of Edenderry Terrace, a group of similar houses built in stages between 1907 and 1909 by the Edenderry Spinning Company, which operated a flax mill to the west of the site.

The house was designed by the Belfast architectural partnership Hill and Kennedy. It is an asymmetrical, two-bay two-storey-with-attic structure, facing east with a rectilinear plan. A two-storey gabled return with internal yard extends to the rear.

The pitched red tile roof features roll-moulded red clay ridge tiles and a single brick chimney with heavy bands and tall clay pots bearing rosette motifs. A wall-head dormer with attic window and half-hipped roof is positioned to the left side (formed jointly with the adjoining property). A replacement skylight has been added centrally to the rear roof.

The walling is Flemish bonded brick to the front, with English Garden Wall bonding to the rear. Roughcast render has been applied to first-floor levels. Decorative terracotta vents are present on both the main façade and rear. All rainwater goods are replacement uPVC.

The principal elevation features two ground-floor openings. The front door is uPVC with a moulded brick surround and camber arch decorated with egg-and-dart motif, surmounted by a deeply projecting flat-roofed canopy in uPVC and timber. To the right is a fully glazed flat-roofed canted bay window above a brick plinth, surmounted by a string course of brick moulding. A central first-floor window has a small roughcast canopy above. All windows are uPVC replacements. Brick sills are painted offset with flat arch heads.

The south elevation is abutted by the adjoining terrace. The rear (west) elevation includes a two-storey pitched-roof return to the right; the west gable contains a central first-floor window and is heavily covered in ivy. A single-storey boundary wall and former coal shed have been largely demolished and replaced with a block wall extending westward with an access door. A timber shed with lean-to roof is abutted to the gable of the return. The rear elevation has a central window and roughcast to the first floor, with an attic window above the return.

The north elevation is abutted by the adjoining property. The setting includes a small front garden with replacement paving, dwarf wall, cast-iron gate and railings fronting Tennent Street, and a long narrow rear garden plot. A paved walkway extends along the rear of all properties in the terrace but has been sealed with locked gates.

The house was built on a previously undeveloped site that formed part of the Edenderry flax spinning mill complex. It first appears on the fourth edition Ordnance Survey map (1920–31) and was added to the valuation record in 1909 at a value of £14. The first occupant was Henry Haddock from County Cavan, followed by Josiah Haddock in 1911. The house was initially listed as No. 8 Edenderry Gardens in the 1910 Street Directory but was later renumbered as part of Tennent Street.

Constructed following the building and sanitation regulations of the late 19th century, the house represents early 20th-century terrace housing design, intended for occupation by a single family with modern amenities including a rear yard accessible by a passage at the front and multiple windows on the main elevation. The building demonstrates detailing from the Arts and Crafts movement, including dormers, bay windows, roughcast and irregular rooflines. The Edenderry Spinning Company retained ownership of the property until at least 1972. The mill continued to operate until 1988, after which the site became an industrial park. The building has undergone late 20th-century repairs and alterations. Although the terrace was designed with Arts and Crafts elements, the group as a whole has suffered from inappropriate incremental changes including loss of historic fabric and detailing, compromising their special architectural and historic interest.
