It’s another place to peer, for example (5,2,7)

I believe the answer is:

house of commons

'example' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?

I don't understand the remainder of the clue.

(Another definition for house of commons that I've seen is " One chamber of Parliament".)

I've seen this clue in The Times.
