About 1 kilometer away from our home is a correct grammar?

The grammar is technically correct, but it's a bit awkward. Here are a few ways to improve it:

More natural options:

* Our home is about 1 kilometer away.

* There's a place about 1 kilometer from our home. (If you're referring to a specific place)

* We live about 1 kilometer from here. (If you're talking to someone in the general vicinity)

The original sentence feels a bit clunky because it puts the distance before the location. The suggestions above make it clearer and sound more natural.
