Coln St Dennis House

Coln St Dennis House is a large house dating from the early to mid-17th century, with extensions added in the mid to late 17th century and the 19th century. It is constructed of limestone rubble with dressed stone quoins, and has a stone slate roof, with ashlar and brick stacks. The building has a rectangular plan, with an early 17th-century range and a later 17th-century range at right angles to the rear right. A 19th-century extension runs along the left gable end of the early range, with a further extension at right angles to the rear left.

The early to mid-17th-century range is two storeys and has an attic. It features a large gabled front at the left and the rear right. The front has a single-light casement with an ovolo-moulded surround, alongside a three-light double-chamfered stone-mullioned casement with a relieving arch to the ground floor. The first floor has a single-light casement with an ovolo-moulded surround and two two-light stone-mullioned casements, one ovolo-moulded. A single ovolo-moulded stone-mullioned casement, retaining some leaded panes, is visible in the gable. All the casements have stopped hoods. A 20th-century part-glazed door is set within a flat-chamfered 'Tudor'-arched dressed stone surround, likely dating to the 19th century, and faces the gable. An 18th-century gabled open-sided timber porch is supported by low dressed stone side walls.

The 19th-century extension has two four-pane sashes with horns to the ground floor, and two two-light stone-mullioned half-dormers. The rear of the 17th-century range contains a single-light and a three-light double-chamfered stone-mullioned casement, again with stopped hoods, along with a four-light stone-mullioned bay window. There is also a single two-light slate-hung roof dormer. Gable-end and axial stacks have moulded cappings, including one single diagonal stack and one twin diagonal stack. The interior has not been inspected.
