3 Tollumgrange Road, Chapeltown, Downpatrick, Co. Down, BT30 7SR

3 Tollumgrange Road is a detached late Victorian farmhouse built around 1875, set prominently close to the road at the east end of Tollumgrange Road in the small rural settlement of Chapeltown, within the townland of Ballyedock Upper and the Lecale Area of Outstanding Natural Beauty. The house is situated in the townland to the west of St Mary's Roman Catholic Chapel, with the former Ballyedock National School and St Mary's church immediately to the east, and a former glebe house directly opposite.

The house is symmetrically composed, two storeys in height and three bays wide, with a rectangular plan. A single-storey gabled porch projects from the centre of the principal south-facing elevation, and a two-storey flat-roofed rear extension was added around 1930. The roof is pitched natural slate with clipped verges, angled clay ridge tiles, and yellow brick gable chimneystacks with gauged brick caps and no pots. Rainwater goods are half-round cast iron. Walls are finished in block-marked cement render with raised quoins.

Windows throughout are generally margin-paned 1/1 timber sliding sashes with horns, set on painted stone sills. A distinctive feature is the decorative 19th-century glazing to the margins of the ground-floor windows, incorporating blue, red and patterned glass. The rear extension has concrete sills rather than stone, and one window within it is a plain 1/1 sash without margins.

The principal south elevation is symmetrically arranged about the central porch, with aligned openings to each bay. The porch has a window to its south gable and, on its west cheek, a six-panelled painted timber entrance door retaining the remains of a cast-iron knocker and a cast-iron knob; the east cheek of the porch is blank. The west gable has a single window at first-floor level on the left. The rear elevation is largely obscured by the extension; the exposed section retains a window at each floor in the left and right bays, preserving aspects of the original rear elevation within the later fabric. The extension has two replacement hardwood entrance doors to its north elevation and two windows of differing sizes at first floor; the west cheek of the extension has a window at each floor, and the east cheek is blank. The east gable has two first-floor windows and is abutted by the framework for an external door that separates the front garden from the rear yard.

The house is set back from the road behind a mature garden with fruit trees in the south-east corner. The boundary is formed by a schist rubble-stone wall with saddleback coping, and the garden is accessed through a wrought-iron pedestrian gate hung on cast-iron piers. A cast-iron cow-tail water pump stands to the rear of the house, and a late 20th-century post box is located at the main gate.

To the rear is a concrete farmyard enclosed on three sides by ranges of outbuildings, with a two-storey barn at the north-west corner. The outbuildings are generally single storey and slated; walls are a mix of schist rubble and in-situ cast concrete. Throughout the ranges, original painted timber sheeted stable doors are retained, some with red brick dressings. The yard-facing elevation of the east range has been modified with semi-circular headed full-height windows and glazed timber doors. Reclaimed patent cast-iron windows have been inserted into the north elevation of the north range, lighting a converted WC block. The barn has external steps formed in concrete, with a timber stair gate at mid-level. The farmyard is accessed from the road via wrought-iron field gates with seven rails and nine stiles. A secondary farmyard to the west, of little architectural interest, contains two Dutch barns and monopitched concrete outbuildings.

The history of the site is well documented. The first edition Ordnance Survey map of 1835 shows a rectangular building on the site aligned along the roadside, with a perpendicular structure on the site of the current west outbuilding. By the second edition map of 1862–3, the outbuilding had been extended to the north and the house appears to have been enlarged, though not yet corresponding to the existing building. The third edition map of 1899–1904 shows the current house in place, without the rear extension, and the farmyard in its current form, though the perpendicular outbuilding is absent, suggesting it was demolished and later rebuilt.

The Townland Valuation records, though not entirely clear due to amendments, likely correspond the property to plot no. 4, described as the house of Nugent Gilchrist, noted as "part built", standing at 6.6 feet in height and valued at £2 5s 6d, with all properties in the townland recorded as exempt. Griffith's Valuation records the occupier as Eugene Gilchrist, holding on land leased from Aubrey de Vere Beauclerk, with house, offices and land; buildings were valued at £5 5s, subsequently revised to £4 10s. Eugene Gilchrist is also shown to have sublet several properties within the townland. The Valuation Revisions record a change in 1874 in which the buildings valuation was raised to £5 10s, likely reflecting construction of the current house, and the ownership transferred to Thomas Gilchrist at this point. New offices are recorded in 1887, with a further rise in valuation to £6 10s in 1889, indicating additional improvements to the farmyard.

The 1901 Census confirms Thomas Gilchrist (aged 72) as head of the household, living with his nephew Peter, his niece Elizabeth, and a female servant named Alice Magorian. The accompanying Buildings Return records the property as a first-class house with ten occupied rooms and thirteen out-offices; the outbuildings comprised two stables, a coach house, three cow houses, one calf house, one dairy, one piggery, one barn and one potato house. In 1903 the property passed to Peter Gilchrist, and the family purchased it outright, probably under the Land Acts, in 1912. The Ordnance Survey Memoirs note that the name Gilchrist is a prevailing name in the parish and is of Scottish origin. The same family remains in occupation today.

In the latter half of the 20th century, the house accommodated a post office, operated from a room in the rear extension with separate rear access, and the distinctive red post box at the farm gate survives as a reminder of this function.

The former landlord, Aubrey de Vere Beauclerk (1840–1898), was the 10th Duke of St Albans and lived for a time at Ardglass Castle. He was a radical politician who was close friends, and possibly intimately involved, with the writer Mary Wollstonecraft Shelley, creator of Frankenstein.

The property retains its original margin-paned windows with decorative coloured glazing, original boundary features in local stone, wrought-iron gates, and the farmyard complex, all of which contribute to the character of the rural settlement of Chapeltown. The house is of local interest for its architectural quality, historic associations, and social history.
