We know that one may not carry anything on Shabbos outside of a private domain (rishut hayachid). A person's house is considered a private domain. My question is: how far outside of the house is considered still part of the private domain?
I have seen many people carry things (like seforim, etc.) to outside patios to use them outside on Shabbos. Is this truly an acceptable practice? How far outside of the house must someone walk to no longer be considered within the house's private domain? Does it matter if it is in the back of the house--away from the street--or in the front of the house? Does it matter if the house has an overhang that the person is sitting beneath? If something is sitting on the end of one's driveway, may he bring it up the driveway on Shabbos as long as it was within his personal property before he picked it up?
