About 4 years ago I had a single detached garage changed to be a single storey side extension, see photos below for before and after.
I now wish to extend above to make a second storey so that we can add two additional rooms - extra bedroom and a study as working from home is going to become more common.
I am not sure how deep or wide the foundations are for the ex-garage but if they are not as wide as the rest of the house are what options are there to ensure there is enough support strength for a second storey or a solution that can be engineered?
Knocking down the existing extension is not an option.
