What is "うち" in "ごろうち"?


I recently came across this sentence:

> たかしは7時ごろうちに帰りました。

I do understand that it probably means たかし came home at around 7, but from
what I learnt to say "around 7" it's:

> ７時ごろ.

So it has no うち. In other words, the うち is throwing me off.

Can someone explain this to me?




If you had the original kanji, it'd be more clear, but as Robusto [mentioned
in the comments](https://japanese.stackexchange.com/questions/14044/what-is-
uchi-in-goro-uchi#comment30246_14044), the うち in your sentence likely refers
to "home" instead of "around".
