Practical answer
How can I divide an open-plan room without walls?
Open rooms divided by routes, light and movable furniture rather than permanent construction.

Map the walking routes first, then give each activity one boundary signal: a rug, lamp, shelf, curtain or the back of a sofa. Repeat one material across the zones so they remain connected.
Start here
Keep direct routes between doors and windows unobstructed.
Use one visual cue per zone instead of decorating mini rooms.
Choose boundaries that can move when the room’s use changes.
