No, there is no need to add the s after "our" in those examples.
Genitive personal pronouns have two forms: a dependent one which is not marked by -s, e.g., our house / their houses etc.,, and an independent one which is marked by s, e.g., This house is ours / theirs. Note that the independent form of "my" is the irregular "mine".
