I would like to have the finished floor above the garage have 9 or 10' ceilings, it is going to be a master bedroom with bath and closet, and wanted to do some sort of either coffered ceiling or tray ceiling

I'm also attaching my plan 10 Gideon lane_V3_2nd floor existing.plan

I can't figure out how to raise the ceiling over my garage in home designer pro 2019, without having something go wrong with the rest of my drawing...Any suggestion??? 10 Gideon lane_V3_2nd floor existing.layout
