Engineering a Distillery in the Scottish Highlands

ROGERS Stirk Harbour + Partners and ARUP - the architects and engineers behind London’s “Cheesegrater” (Leadenhall) skyscraper - have designed a new 14,800 square metre (159,300 square foot) showcase distillery for Macallan, one of Scotland’s largest whisky producers.

Located in the Scottish Highlands the new distillery is partly inserted into the landscape and features an undulating green roof.

This unique design is reference to the region’s mountainous topography and acts to preserve and enhance the unique landscape.

Over 400 workers built the 220 metre (722 foot) long, 60 metre (197 foot) wide building, which required the removal of over half a million tonnes of soil prior to construction. Its 300 millimetre (11.8 inch) thick outer walls were poured in-situ.

Each of the four domes within the roof houses a cluster of hand-hammered copper stills and fermentation tanks.

The roof is held up by a steel structure, which was designed and built with a tolerance of just 10 millimetres.

The roof itself is not really curved, but based on a triangulated 3-metre matrix. Its complex geometry was modelled using parametric software to ensure stability and load-bearing capacity.

Austrian timber specialist Wiehag converted this geometry into 1800 individual glulam beams and 2,500 triangular timber elements that make up the roof’s surface. As no two components of the roof are alike, they were numbered and assembled individually.

This £140 million facility is more than just a showcase project: its completion means that the Macallan distillery can now increase its output by up to 30%.
