Allt Dinnie, Birsemore

Allt Dinnie is a villa dating from the later 19th century with a two-story Italianate tower added in the late 19th or early 20th century. The villa is constructed of finely finished, squared and snecked granite with long and short quoins. It has overhanging eaves with timber bargeboards.

The west-facing principal elevation is asymmetrical, featuring an early 20th century decorative timber porch, which forms a balcony for the attic floor of three bays on the right side. To the left of the porch is a single window, and in the centre a canted four-light window. A canted four-light window is also located on the right side at ground floor level. A glazed opening is located to the left of the attic floor. A square-plan, part-engaged tower is advanced to the penultimate bay on the left, with a bipartite window to the centre of the ground floor. A panelled timber door with a semi-circular fanlight is set within the right return at ground floor level, flanked to the left by a pink granite "cheese press" and a window above the balcony. A rough-faced dividing band course is present, and the tower has three round-arched single-pane windows on each elevation of the first floor. A dentil-moulded eaves cornice runs beneath the deeply overhanging eaves, which support a shallow pyramidal slate roof topped with an iron weathervane. There is a window on the ground floor of the outer left bay, and a gabled dormer with a canted roof encloses a window to the attic floor above.

The south elevation is also asymmetrical and two-bayed. An advanced bay to the left features a rectangular-plan tripartite window at ground floor level, topped by a four-light timber window that breaks the eaves to the attic floor. Irregular fenestration and lean-to additions are visible on the right return. A gabled bay to the right contains a timber doorway flanked by windows at ground floor level, with a bipartite window set in the gablehead.

The east-facing elevation is asymmetrical and two-bayed, with a gabled bay projecting to the right and regular window placement.

The north-facing elevation is asymmetrical, with a gabled bay to the right. A tripartite, rectangular plan window is advanced to the ground floor, accessed by two stone steps, and another tripartite window is set in the gablehead. Flanking bays to the left were not visible in 1999.

The villa has predominantly two and four-pane timber sash and case windows, and a purple-grey slate roof with lead ridges. Coped granite wallhead and gablehead stacks, topped with circular cans, are also present, along with cast-iron rainwater goods. The interior was not inspected in 1999.

Decorative cast-iron gates and gatepiers are located to the southeast of the house, with a pedestrian gate flanking to the east.
