Shannagh More, 47 Ballagh Road, Newcastle, Co Down, BT34 0LA

Shannagh More is a two-storey, four-bay house built in the early 1920s for the Newell Family within the grounds of their earlier house (since demolished in the 1980s). It is constructed in random granite rubble with a natural slate roof, hipped with deep spreading eaves and granite chimneys at either end, the right-hand one aligned along the ridge.

The south front elevation is asymmetrical. The off-centre main entrance, positioned in the third bay from the left, is sheltered by a porch with a flat concrete roof supported on two stone pillars splayed to resemble elephants' legs. The ground floor windows flanking the entrance are set within segmental bays, each topped with a curved natural slate roof and containing seven-light windows with leaded transoms. The left bay features a triple-paned window with leaded transoms, a treatment repeated across four equi-spaced first-floor windows. All windows throughout the house have metal frames with granite voussoired heads and concrete cills.

The west elevation, which faces the driveway, is dominated by a protruding balcony of similar construction and character to the porch. This balcony is accessed via French windows from the first floor and is furnished with a metal balustrade and metal fire escape. A small ground-floor window sits within this gable.

The north elevation has been compromised by a later two-storey extension at the left, linked to the main block by a short two-storey link. Despite this addition, the original windows and stonework of the main building survive unaltered, though the latter has undergone strap pointing. Four metal casement windows occupy the first-floor level. The extension itself is cement-rendered with a monopitched roof.

The east elevation contains a ground-floor flat-roofed rectangular bay with French doors, a tripartite window to its right, and two further tripartite windows on the first floor.

The house's architectural style—particularly the spreading eaves and splayed columns—is said to reflect that of a Ceylon tea-planter's residence. Its value is compromised by internal alterations and by a modern extension to the rear.

Associated features include a water reservoir to the west, which once powered a turbine for electricity generation. The turbine house, a small single-storey structure with random granite walls and a vaulted stone roof, survives though both turbine and generator have been removed. The main road gateposts are constructed of rusticated granite blocks with projecting pyramidal caps and have been reset, likely when sight lines from the avenue were improved. A short distance south of the entrance gates, a sub-rectangular dressed-granite trough is set into a niche along the boundary wall; its water-feed spout is mounted in a raised rectangular granite panel inscribed '1917'. The original boundary walls appear to have been reduced in height to improve sight lines for the current owners.

The house is shown on the 1938 Ordnance Survey 6-inch map but does not appear on the 1920 edition, nor in the 1900–23 valuation revision books. It was successively occupied by the Tutims, Prentices, and the Southern Education and Library Board from 1977 onwards. The property now operates as an outdoor pursuits centre.
