See, the "your" in there is what we call a possessive pronoun. It indicates that something (in this case, my porch) is owned by someone (in this case, me). That makes what you are proposing doing a property rights issue, not cultural criticism.
There's actually a housing shortage in the US so it's not like this is an architecture that is responsive to consumer or cultural preference and demand - local zoning laws do not even permit such freedom.
