Tunnel House

Tunnel House is a detached house built in the late 18th century, with alterations made in the early 19th century. The main south facade is constructed of limestone ashlar, while the remaining walls are rendered with ashlar dressings, copings, end gable stacks, and a slate roof. The building has a double-depth plan featuring a central entrance that leads to a staircase, with two reception rooms on either side.

The exterior is three stories high and has a three-window range. The south front includes a plat band above the ground-floor windows, sills on the upper floors, a plain cornice, and a blind parapet that ramps up to the stacks on the return walls. The ground-floor openings consist of late 20th-century French windows, while the upper floors feature late 20th-century multi-paned casements. The central recessed doorway has an early 19th-century eight-panel door with a decorative fanlight above, which is obscured by a modern canopy.

Inside, the entrance hall has stone flags, and there is an open well late 18th-century staircase with a deal handrail and stick balusters. Several early 19th-century reeded cornices and similar surrounds can be found around the doorways. The back right-hand room on the ground floor contains two early 19th-century china cupboards with shelving. The bedrooms feature early 19th-century chimneypieces with stopped roundel or reeded surrounds and contemporary grates.

The house is named Tunnel House because the Great Western Railway's Bristol to London line was built directly underneath it. Isambard Kingdom Brunel purchased the property in April 1836 and conveyed it to the Great Western Railway company in December 1837; the railway line was opened in 1840.
