What Do the Hosts Picture When Belinda Blinked Says Chalet?

At the start of the chapter, Jamie Morton, James Cooper, and Alice Levine stop on the word. One of them pictures beach huts, the wooden sheds on the sand, and is told that is a beach hut, not a chalet. Another thinks of the log cabins at Center Parcs. Another associates a chalet with skiing. They add that James's mother used the word for the garden shed, and that Rocky Flintstone had just built a shed at the bottom of his garden and called it the pavilion, which may be where he writes. The chapter itself is the Duchess taking Belinda off during the company party. The argument happens before anyone reaches the door.
