If I were my own suggestion, I would do it like this 1. The raft foundation thickness may be more economical 2. There are protrusions in the architecture, don't you apply it to the static 3. You can remove the k23 beam and lay the cassette in that area (you can do the same with your symmetrical) 4.25/50 beams, you can make some of them continuous and in the same size (for example 02 You can make your beam 60730) It would be more appropriate if it was made parallel to the small edge in 5. rib beams.
