We are considering buying a home with a block foundation basement that the owners added a second story atop. We would like to add an addition next to the block one. The block basement we would be adding to has two L shapes to it. We would also have to dig the new basement lower than the old block basement. Would this undermine the existing block basement?
Can we pour the new basement right next to the block one or would this cause the block one to collapse. Please let me know if this is commonly done and is it much more expensive than just pouring a new basement without worrying about the old one. Any suggestions you have would be greatly appreciated. We really enjoy your show. Thanks for the help
