came to see me to/at my house

[NAL123]

Consider these sentences of mine, please:

1) He came to see me to my house.
2) He came to see me at my house.
3) I will come for you to your office at 1pm sharp, so be ready.
4) I will come for you at your office at 1pm sharp, so be ready.

Which are correct between 1 and 2, and 3 and 4?
As far as I know, it should be "come to a place", and not "come at a place".

#2 and #4 are correct, as are;

1a) He came to my house to see me.
3a) I will come to your office for you at 1pm sharp, so be ready.

I think the same reasoning applies to:

Please come to room number 3 for your interview. (an announcement for an interview)

Please come for your interview in room number 3.

Am I right?
