Douglas fir grown in Dumfries and Galloway was used to clad the exterior of the new Natural Power office near Dalry. Douglas fir was chosen because it is particularly stable and could be sourced very close to the office - within a 2 mile radius. The boards were cut and air dried on site. They are vertical, rough sawn boards and measure 25mm by 150mm. The office was designed by Neil Sutherland, Architect, who was careful to design the building in such a way as to protect the cladding from prevailing weather and maximise its lifespan.
