Usually, when we use a
preposition with a place, we have got 3
parts.
1. You
begin with a preposition, the
prepositions are in, to, on, at under,
behind, over, up, through, with, from, among, and
between.
2. In the middle, you
put a, an, or the OR a possessive pronoun (my,
his, our, etc.) OR
this/that, these/those. One and
only one of these middle words.
NOT the my/ his that.
3. You
end with a
noun of place (the house).
Like this:
in our house
This rule is good for 95% of cases.
