The design approach was aimed at meeting the BREEAM ‘Excellent’ target, and sustainability targets that included a 100-year design life. Wood formed the basis for both the structure and the ongoing heating, with a wood-fired carbon-neutral heating system.

 

The complex roof geometry incorporates six elliptical domes, whose undulating contours are covered internally by a western red cedar panel lining. Constructed directly over the chamber and continuing up to the roof level, is a stunning 12 metre high ‘funnel’ structure, also clad in pre-formed cedar panels. Combined, a total of 60,000 linear metres of cedar was used on this project.
