Camstraddan House

Camstraddan House is an earlier 19th century Classical house that underwent later 19th century alterations. It is a two-storey, three-bay structure featuring pavilions, with a painted harl finish and sandstone ashlar margins and dressings. The building includes quoin strips and an eaves moulding.

On the southeast (main) elevation, there is a sandstone corniced door surround with a moulded entablature, displaying the Colquhoun Arms. Flanking the entrance are canted windows at ground level. The first floor has three windows arranged symmetrically, with a single window at the center and bipartite windows on either side. To the right is a lower two-storey pavilion wing with a bipartite window at ground level and a piended dormer head above. A service block is also located to the right, featuring a later bow-ended glass house built against it. To the outer left is a single-storey lean-to wing.

The northwest (rear) elevation is finished in rough cement render. It features a three-bay main block with a transomed and mullioned stair window at the center, flanked by smaller windows to the left. There is a small window at ground level in the center, with a larger window on either side and ventilation grids at the base. A single-storey lean-to bay is located to the outer right, with a window at the center. To the left is a taller block, which serves as the service wing.

The southwest (side) elevation includes a lean-to piend-roofed block with a central door and flanking windows, while the area above is a blank wall. The windows throughout the house are plate glass and four-pane timber sash and case. The roof is covered in grey slate with lead flashings, and there are broad corniced wallhead stacks with circular cans.

The interior was not seen in 1996.

In the grounds, there is an obelisk sundial made of ashlar stone. It features a square shaft with a faceted octagonal capital topped with an obelisk finial on a simple stone base. The sundial has cup, heart, and triangular-shaped carvings, but no remaining gnomons.

Additionally, there is a single-storey rectangular-plan lodge constructed of painted rubble with painted margins and a grey slate roof with lead flashings.

The boundary wall is made of rubble with slab coping, and it includes rubble piers topped with sandstone moulded caps and ball finials.
