I currently own a 1925 side hall colonial in staten island, new York. In the 1980's and extension was added to the back of the home. It's a two story structure with a crawl space beneath it. In an attempt to gain more living space, my wife and I are considering having the crawl space excavated, thereby extending the original basement. Our questions are:
What is the best way to do this? We have been told that removing the wall that faces the driveway may be best. By doing this we could get some heavy machinery in there. However I am certain this would be the most costly method. Any suggestions?
Whichever way we do it, our main concern is that the job is done right. The last thing we want are structural problems.
This project would also include breaking through the existing cinder block back wall of the basement. The crawl space has a concrete slab base. The joists for the flooring are about 2 to 2 1/2 feet above the slab.
