I also don’t understand why the OP doesn’t rotate the bed. Because of the window on the front side? If that were a highlight, I could understand, but so far I only see random memory.I don't want to be a spoilsport, but with a width of 3.62 RBM up there between the exterior wall and the stairs (bathroom/bedroom), furnishing the new bedroom won’t work if you add a wardrobe next to the double bed and expect to still comfortably get out of bed.
You lose about 2 cm per wall due to plaster. 60 cm is quite tight. It certainly works, but we have calculated with 80 cm. For comparison, we have a width of 3.85m and I wouldn’t put a large closet next to the bed there anymore. We only place a dresser with a depth of 30 cm. You don’t want to squeeze along the bed in the house. After all, it’s a house; it should all be a bit more spacious when you have the opportunity.Thank you for the comment. The walls are supposed to be 11.5 cm thick. How much do you lose due to plaster, etc.? We have adjusted the floor plan to have 3.75m RBM. That should be enough for us. The bed is 1.90m and we have calculated 60cm space on each side. That should work well, right?
