I checked these in preview on my own small and don't see a problem with the size. They're furnishing that you'd want to design around as opposed to trying to insert into an existing design. They're also using up space, which helps meet player demands for more items that will make yards feel less empty.

I agree that a half size version of the reflecting pool would be a welcome option regardless. But I don't see how the raised deck could be made any smaller and still have the same furnishing detail. The Ivy-canopied Deck is close to the same thing for those who want something smaller.
