Subtracting Stroke to Create Negative Space

Hiya! I've been designing in Photoshop for around 5 years now, and recently have decided to learn Illustrator. I'm trying to work on a concept design, but I cannot figure out how to do what I want and was hoping someone would help.

 

Below I have attached an image of my current file. My goal is to remove the black stroke (create transparency, while also deleting the underlying fill of white that the shape has). 

 

Things that I have tried are Object > Expand and Shape Builder tool. Other than this, I'm not sure what I'd be able to do besides unorthadoxly resizing each shape.. which would create improper proportions for what I want.

 

All it is right now is 3 black rectangles manipulated with the shape tool, and an added black inside stroke of 7pt.

 

Thanks y'all.

Outline the stroke, you'll get a compound shape that was the stroke plus the original shape (white), direct selection tool click on the white, select same fill, delete, you'll be left with the compound path, adjust opacity as desired...

You could also apply the Offset path effect with a negative value.

 

(Effect > Path > Offset path)

Like this?

Remove the stroke from the shapes.

Group them, then add a stroke at group level.

Make the stroke 0% opacity.

In the transparency options for the group, tick 'Knockout Group'.

You're amazing... thanks so much! Guess this shows my lack of experience with Illustrator LOL.
