Calder House

Calder House is a mansion dating from the 16th to 17th century, which incorporates walls from an earlier fortalice. It has a traditional L-plan layout, with a main block that is three storeys high, including low floors to the north, and a garret. The exterior is constructed of random rubble and features gabled, slated roofs. Notable architectural elements include corbie steps and a buttress at the west end, as well as skews, oculi, and corner stones at the eastern extension. The chimney heads are rusticated.

The northwest wing, which was extended in the later 17th century, is four storeys tall with a low floor and includes similar skews at its gable end. Additional structures were built around 1780 and in 1880, located in the re-entrant angle and on the west side of the wing.

The interior of Calder House has been greatly altered. The older part of the first storey of the main block contains three contiguous vaulted chambers. Above this, the drawing room, also known as the Great Hall, features pine panelling and tall windows. The kitchen and a fine scale-and-platt stair are located in the wing.
