Case studies

The David Douglas Pavilion, a small but innovative new building constructed almost entirely of Douglas fir, is the central feature of the Scottish Plant Collectors Garden at Pitlochry.

The theatre accommodates a variety of formats to suit drama, dance, music theatre and musical performances as well as school assemblies. It is also a highly sustainable, low carbon building, achieved by the use of a timber structure and cladding together with a natural cooling and ventilation strategy.
