The only natural use of "some house" or "some other house" or anything similar is when it's used in a casual way to mean "a different house but I can't really be bothered to tell you which one". For example, here is a rather convoluted invented dialogue which includes the phrase:
- What did you do on Saturday evening?
- I went to a party.
- At Dave's house.
- Was it good?
- Not really. At about 11pm, we ditched it and went to a different party.
- Where was that?
- Can't remember.
- Come on, please try. I want to know where the other party was.
- Really, I don't know. It was just at some other house! Now stop hassling me about it.
I can't think of even a convoluted way of incorporating "some other" in the same way (ie without a noun after it).
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
