If it matters we have slab foundation.
Not without consulting a structural & civil engineer! You may have several bearing issues that will require beams and columns for support.
Yes, you can. We don’t specialize in doing this but I know some contractors that do. First you would need to contact a GC (general contractor). Reason you would want to hire a GC to supervise the process is so that it all goes as planned and the liability is on them. They will line up crews to come in and disconnect your electrical, plumbing, etc. Then, depending on the house, someone will come in and raise the house up off the foundation it’s on now. Now the demo starts, they will dig out your basement to your desired depth, pour your footings, form your walls, then pour your new basement. After all that mess is complete they will lower your house back on top of the walls. (Check building codes and soil to make sure you can dig down first.)
A crawlspace is the space under the house which provides access to the plumbing, electrical, and heating systems of the home. The height of the crawlspace can range from just 1-foot of space to 4-feet. Some crawlspaces share similarities with basements, but they are generally on a dirt floor with little insulation.
It is impossible to have a crawlspace as an extra living space. Many people use them for storage; however, it is mostly for outdoor equipment that will not be affected by the humidity and exposure to outside temperatures.
Do it right the first time, hire a good general contractor with a good safe approach. Make sure he is knowledgeable in that particular scope of work.
I am a contractor myself and heard of a case where a house partially collapsed during the basement digout. It was due to improper bracing and house weight distribution. They dug too close to the foundation resulting in insufficient lateral support on soil under foundation. Luckily no one got hurt but the project was stopped until proper engineering was made and a new safe approach was implemented. The homeowner didn’t have to pay extra but I could imagine what a head ache it was.
Bad idea. just add on or buy a new house.
i do not believe it is possible, as the height of the crawlspace is very low, never meant to be a basement. basements cost more to do from the beginning of building the house. crawlspace costs less. there is also a minimum height for ceiling height to pass inspection.
You will have to most likely extend the foundation down to support the existing foundation. This is a difficult job and should be done by an experienced contractor.
