All I can say is I hope they aren't finished yet!

What are we seeing here?? Whatever it is, it's done poorly.

You are looking at the bottom edge of a hood enclosure with the built in exhaust fan element installed. It is not a complete hood/exhaust fan, but a built in. The desire is to give it the same look as a complete hood/exhaust fan combination. Your thoughts appreciated on this incomplete project.

Start over and use an insert ( not a regular hood covered with drywall) designed to have a surround. Then have someone who knows what they are doing do the project. That's not salvageable.

It does have an insert, it is not a hood covered with drywall
