Redesigning the layout of rooms in the house

Hello I am taking on the design of my own home, however, I do not have enough experience and sense regarding the layout of the rooms. I found a project that suits most of my criteria, but I would like to change a few things in its right part (the projection of the building attached to the project - red color ). I would like someone to modify the room layout so that: - access to the bathroom from the master bedroom if somehow it coould work in such home; - increasing rooms 8 and 9 to around 13 m2 at the expense of room 7; - the whole house is to contain (except the living room and a small toilet) 3 bedrooms and 2 small rooms (one as a cabinet for the second document for various other junklumber) each could even be as small as 6-8 m2 I am open to various modern proposals. The whole house will be designed from scratch, so the location of load-bearing walls is not important. If you have any questions, I will be happy to answer you. For those interested, i will provide a projection of the building in .dxf or .dwg related to the direction of the world (sun directions)
