How is that supposed to work if you don't have any measurements? According to the picture, the room is already full. What do you want to throw away - everything except the measured bed? Whether a door is 70 or 90 cm wide makes a difference. Likewise, where and at what height, for example, the window starts or how big the radiator is. You can't even tell from the drawing which wall is longer...
You want free help here and don't even want to do such simple things? :rolleyes:
