[Grammar] On the outskirts of the city,

[Nikitus]

Hello.

Are the following sentences grammatically correct?

"On the outskirts of the city, inside a warehouse, which has been abandoned for years, three men were talking about the robbery they will commit shortly in a small grocery store."

Thanks.

It's just one sentence, but it seems okay. Consider rephrasing it as follows:
"In an abandoned warehouse on the outskirts of the city, three men were discussing the robbery they would soon commit in a small grocery store."
