180 Mullalelish Road, Derryhale, Portadown, Co Armagh, BT62 3TQ

180 Mullalelish Road is a single-storey vernacular dwelling located in the townland of Derryhale near Portadown, Co Armagh. Formally recorded as existing in the early 19th century, it may be considerably older. The building is Grade B1 listed and comprises the house and barn.

The property occupies a picturesque sloping site and faces east following the contour of the ground, with the barn positioned at the lower end. It stands gable to the road, set back a short distance within the plot and enclosed by timber fencing with elaborate timber gates.

The central portion of the building is thatched without visible skews, as natural slate roofs abut it on both the south and north sides. The thatch exhibits remains of decoration along the ridge and has plain, square-cut eaves. The wall construction comprises mud and stone at the centre, with stone or brick used on the end sections and the projecting entrance porch. The mud construction is exposed at four locations. Two rendered chimneystacks with corbelled and slate cappings rise from the building: one serves the kitchen hearth between the thatched and slated sections, and the other rises from the north gable above the parlour fireplace.

The south-facing elevation, flanking the entrance, features three vertically sliding windows with plain sashes and no sash stops, with sills of traditional depths (the second and third windows having reduced sill levels). The slated section to the north has two similar windows. All windows have exposed framing. The barn at the southern end has a small unglazed opening in the gable and is entered by a stable door. A windbreak porch with curved jambs and sheeted door occupies the northern extremity, with thatch extending over it. The north gable is blank but displays the ends of a sawn purlin projecting slightly below the timber bargeboard.

The rear elevation incorporates a top-hung timber window lighting the back bedroom, two galvanised water tanks, and a multi-paned metal casement window lighting the kitchen. A gabled projection with natural slate roof extends from this side. The timber-sheeted door on the north side of this projection is flanked by a fixed metal window of three horizontal panes, with a top-hung timber window on the opposite side. A small top-hung window in the thatched part, a timber-sheeted door providing access to the barn, and a toilet projection with lean-to corrugated iron roof complete this elevation. The toilet has a timber-sheeted door on the north side and a plain top-hung timber window on the west side. Sills are generally of traditional depths at leading faces, though those lighting the north side of the kitchen and the toilet lack sills. Gutters throughout are of metal, carried on drive-in hooks.

Historical records show a building matching the present structure on the Ordnance Survey map of 1835, with a small outbuilding to the west. The 1860 revised map shows a similar layout but with a considerably larger outbuilding. The property is recorded in the 1862 valuation as the home of Alexander Lappan, with Mrs Bacon as immediate lessor and a rateable value of £1-5-0. A barn was constructed to the south of the house at some point after 1860. Both this barn and the outbuilding were demolished after 1967, with a 2003 survey confirming that only the dwelling remained. The building represents a good example of vernacular architecture incorporating important mud-wall construction and is notable for the arrangement of its elements with natural slate roofs on either side of the thatched central section.
