OK, so this is not actually in Ottawa, but I just had to share this! In the past I published a post on conversation pits in 1970s housing design: The Conversation Pit. I was just perusing through some old articles I had on my favourite tract house architect, the late Barry Berkus, and I happened upon this article from the May 1969 issue of House & Home magazine. One of Berkus's designs in Valencia Hills California has a "fenced martini pit". I love how it is specifically a "martini pit", but also the fact that it is fenced - presumably to keep martini drinkers in the pit and not free to wander around the house!
