Glass House, Drumlanrig Estate

The Glass House at Drumlanrig Estate was designed by architect Charles Howitt and built around 1877. It is a large, 10-bay, lectern-shaped structure that features a unique design, rising over the rear wall to create a buttressed clerestory. At the back (north), there is a lower lean-to that serves as a boiler house, store, and office, extending the full length of the glass house.

The glass house has a polished red ashlar base and vertical supports that carry the roof timbers, with a door on either side. The lean-to is constructed from rubble with ashlar dressings and includes three doors facing north, along with four small-paned sash windows. The roof of the lean-to is continuous and covered with graded slates, and there is a modern boiler chimney.

Inside the glass house, there is continuous shelving along three sides and a perimeter passageway surrounding a rectangular bedding area, which has a red ashlar wall. Thin iron columns support the roof timbers in the bays.
