Unhappy lowering a basement floor

My husband is interested in lower our basement floor. How can he do that safely without compromising the structure of the house. We want to lower it about an extra foot or two.

Basement floor

What type of foundation construction do you have? Is current basement floor concrete?

Without knowing the specifics wirepuller asked about, I would suggest talking to a couple of contractors, you could be opening a huge can of worms.

I almost had that done with my basement and I kinda wiish I had. Too much work for my tired self but it's pretty simple. They (notice I say they not I lol) chip up the old floor and dig down. All support columns must have footers poured or repoured along with the deck. It is a huge amount of work and not really a DYI project.

To do it properly, you must be well inside the footings by an amount you are below the original level. Just a foot or two of extra depth makes a big difference in the load on the wall system.

Not a DIY project.

First check code there for what you will have to do. For how far away you have to stay from the footing you have now.
