Why was the design created this way?
Based on the forum and what we actually need

What is the most important / fundamental question about the floor plan, summarized in 130 characters?

The sloping ceilings concern me a bit. On the upper floor plan, I drew a 1.2m (4 ft) line, where the ceiling height should be 2m (6 ft 7 inches). I assume a knee wall of 80cm (31 inches) (since 75cm (30 inches) is measured on the outside). Otherwise, we hope you can point out “blind spots” we no longer see 🙂

Thank you in advance for your constructive criticism.
I hope we haven’t forgotten anything.

Best regards
