Mayne frequently thumbs his nose at convention—you expected this, but I'll give you that. A large overhang, for example, seems to be there to shade the adjacent walkway, but it doesn't—quite. The complicated structure might suggest a giant garden pergola, if it didn't resemble the unpoetic underside of stadium bleachers. Such jarring effects are either challenging or irritating, depending on your point of view. I admire Mayne's sense of architectural conviction, and it's not that public buildings can't occasionally flaunt convention, but in his case, the flaunting seems both willful and arbitrary, the architectural equivalent of wearing a baseball cap backward.
