Troy House

Troy House is a mansion built in three distinct phases, with the appearance largely defined by an imposing late 17th-century classical block on the north side. This main block is constructed from mixed random rubble with red sandstone dressings and a slate roof. It follows a double-pile plan and has a hipped, two-span roof, rising to three storeys plus attics, with a full basement level.

The north facade is a symmetrical composition of four, five, and four bays, with the central three bays projecting slightly and topped by a pediment. Regular dressed quoins mark this central projection and the outer corners. A prominent, T-plan stone staircase, featuring nosings on the steps and solid ashlar parapets with plain, ramped copings, leads to a large doorway framed by a moulded architrave and a swan-neck pediment resting on consoles, enclosing tall, panelled double doors. The ground-floor windows (the piano nobile) are tall, 24-paned hornless sash windows with simple architraves, each with a shallow relieving arch of rubble above. Similar rubble arches are above the basement windows, which now have modern joinery and glazing arranged in a cross-window pattern. Second-floor windows feature cross-window joinery and small-paned glazing. The roof is punctuated by four gabled dormers on each side of the central pediment, each containing a small-paned, two-light casement window. Four wide ashlar chimneys with cornices at the tops rise between the roof ridges. The three-bay west return wall mirrors the fenestration, although the first-floor windows have cross-window joinery and small-paned glazing.

According to historical records, a smaller, four-bay, four-storey 18th-century block is set back at the east end, concealing an early 17th-century wing, which was originally built for Sir Charles Somerset. A further wing projects to the south, also likely from the early 17th century.

While not currently visible, reports indicate that the central hall leads to a state dining room on the left and a suite of withdrawing rooms on the right. A broad staircase, located in a large, square volume at the rear of the hall, rises through two storeys. This staircase is described as magnificently spacious and open-well, with thick, twisted balusters grouped in fours and a ramped handrail. Plaster ceilings are also noted among the interior features.
