"Jestem z przodu domu" sounds very unnatural to me. I would say "Jestem przed domem" ;)
Which of the phrases is more commonly used, this or "Jestem przed domem"?
Native here. "Jestem przed domem" is definitely more commonly used. "Jestem z przodu domu" seem rather unnatural.
For some time after you became more active in the forums, I thought you are Polish. Can I ask what's your background? :)
