I got out of the car and walked the few kilometers my friend's home

[tufguy]

We say "I got out of the car and walked the few kilometers home." Do we say "I got out of the car and walked the few kilometers my friend's home"?

No. If it's someone else's home, you need to add "to".

Home is a tough one, Tufguy. It often stands alone with no room for a preposition, as in I walked home. At other times, a preposition is optional, though it may change the meaning slightly: I wasn't [at] home.

You may also see another use of home, where it's a short version of "home base", the first of the four bases on a baseball diamond. Some baseball-derived idioms have become so universal that they've been adopted into British English.
