Can't say I've ever heard of parking structure. I've heard of multi-story car parks and lock-ups (private garages rented from the local council by home owners, which stand in a row at the bottom of the street). Also parking bays (where it's not a garage as such, but the parking areas outside homes are covered with a roof on pillars, to give some protection from the elements, but the sides and front are open to the air).
But, as always, that comes with a caveat that the UK is a big place, made up of many regions and more than one country, all with their own phrases. So just because I've never heard of it doesn't mean it's not in use somewhere.
Artemis, I'm not sure what your biscuits would be. From the description, I think the closest might be scones - but few people would have those for breakfast.
