26 Ancaster Square

26 Ancaster Square is a house that has been heavily modernised on the interior and at the rear, but it is listed because its main front, or principal elevation, remains largely unchanged and features 18th century materials similar to those of the nearby No 24, which has its own separate listing. The house is prominently located in the center of the southern range of Ancaster Square, contributing to the overall character of the square. This square was designed as the focal point of the planned town of Callander in the late 18th century and continues to serve as its centerpiece.

The principal elevation faces northeast across the square, with a centrally located main door. To the left of the door is an inserted bi-partite window, and there are three evenly spaced windows on the first floor near the eaves. The southeast gable is attached to 28 Ancaster Square, while the northwest gable connects to 24 Ancaster Square.

The rear southwest elevation has been heavily modernised.

The building features painted render on the walls, with painted stone margins around the openings. It has a timber two-leaf door and timber sash and case windows. The roof is pitched and covered with grey slate, and there is a shared rendered ridge stack with cans on both the northwest and southeast sides.
