How do you turn a crawlspace into a basement?

I have a good size crawlspace that I would like to turn into a basement.

You will need to either increase the size of the floor or ceiling by raising the supports or lowering the foundation.

There are many ways to do this but basically it is like any unfinished area. You will probably have to fir the walls and insulate them before you sheetrock them. Also you will have to pour concrete for the floor. All of this depend greatly on what condition the area is in and how much space you are stating with.

You will need to install flooring, lighting and ventilation. Make sure you have windows and a stairwell and viola... you have your basement.

First dig a ramp into the crawlspace and then keep digging to the depth you want. At each support, use a post to shore it up. When you reach your target depth, pour a concrete footing and use an adjustable steel post. Once you've excavated to the foundation wall, pour the basement floor.

First you need to check the existing supports. Next, use plywood to create a floor overtop of what you have already and insulate.

The amount of effort required may be substantial. You must shore up the existing foundation in order to dig out the the fill within your crawlspace to start.

Check the height first! If you can't stand up in the finished basement then it will still be a crawlspace.

That's a tricky one. You're going to have to get in there and just dig it all up until it's the size of the basement you want. I would advise that you hire someone.

Get a crane and lift your house. Then have contractors build a basement and lower the house onto your new basement.

Get a licensced contractor to do the work for you. Done wrong, may lead to mold issues and other problems you won't want to deal with.

one of the most important things to look at is water drainage. also, look to see if you have a good foundation. you would probably need some kind of flooring.
