Hi I currently own a semi detached house with attached garage. The garage is full length of the house and currently converted into a bedroom and half of the rear kitchen. The garage has a tiled roof. There is a crawl space under my house about 4 foot. Would you say the foundations are stable for the extension on top of the garage already? Would I still need to dig a test hole outside the house to please building control.
Cheers
Mark
