Dear client,
based on your explanation, I put master room in the east and And I assigned a bigger bathroom to the master's room and changed the location of the door so that the master can use it exclusively.
In the upper part, I assigned the bedroom to the guest bedroom, which can be extended to two beds. The guest bedroom door has been changed to place the service outside the bedroom. Not changing the arrangement of services due to water and sewage pipes, which may cost you a lot.
Next to the wc, I dedicated a part to the laundry.
Also, I separated the space between the office and the living room with a partition, which can be made of glass or wood, which can be easily folded and the space will be bigger if there are guests. Inside the office, I put a work extension in addition to a sofa bed that can be used by your guests.
