I made such a study to put my foundations on the adjacent side to -0.5 (my normal foundation level is -2.5) due to the adjacent order on two sides and the absence of basements of these adjacent buildings. I can't understand why it's high. Is it the proximity of the foundation and the rigid diaphragm to each other? Knowing that it is not a correct solution, I can always get a report by laying a raft foundation in basic dimensions (since the raft does not basically check for cutting safety), two projects are attached. Thank you for your comments and help.
