The award was presented at the Sibelius Hall, Finland's showpiece of contemporary timber construction, with a nearperfect acoustic. However, remedial work to the three-yearold building was needed over the summer, not to the timber but to the glass screens that enclose the building. The culprit was the weather. In a normal year, Finland has a wide range of temperatures, from cold winters to very pleasant summers. The glazing, described as 'hanging like a shower curtain', has an 8cm space at its base to allow for expansion. But this year the summer was exceptionally hot and, between January and June, an expansion of 7.3cm was noted.
This rang alarm bells, and the expansion space was increased.
