Digging Down Basement Floor

And the mechanical room with a cross section so you can see how far down we went.
Digging down basement floor. If you need to start digging down however or you have no space under your floors at all at present then the cost will be at least double. I would like to dig out the 1 foot to 2 feet of the basement floor to achieve ceiling heights of around 7 6 to 8 6 to make to the basement a usable dwelling unit. After removing the concrete and a little bit of digging. Lots of head room for a comfortable apartment.
Loss of my backyard parking space. Digging down a few feet means removing dirt and concrete making new concrete footings below the existing ones and pouring a new concrete slab floor. The new floor ended up close to the level of the top of the footers. If you already have a basement then converting it to living space will cost about the same as converting your loft.
Noise from some jack hammering. Check my blog post on an in depth guide on flooring options once you are done lowering the basement. After the digging was mostly finished. In simple terms your dig out the dirt to make enough headroom extend the foundation all the way below fix the drainage system put in a floor and finish up the basement.
That could have been prevented by putting down rozen paper before the work started. Down side to the dig out. Digging basement deeper cost versus a loft conversion. There was lots of dust on our first floor.
If you are making a new basement where there is only a crawl space or if your existing foundation is not structurally adequate it may require lifting your house while the new foundation walls.
