I have a similar hallway, but it is a bit wider. It works, but it’s not super practical. What surprises me, regardless of the planning here, is the size of the utility room. I have the "small technical equipment" in the hallway, behind the door that swings open. Water connection, telecom, meter box, converter. Everything fits nicely shallow against the wall. Nothing sticks out more than 20 cm. In the actual utility room, I have the ventilation system, the hot water tank, washing machine, filter system for rainwater washing machine, heat pump control, and a 90x50 shelf. The room is almost 300x100. That way I only use 4 sqm. So why does one need 8 sqm in a house? If the saved sqm can be added to the hallway, then it could also become sufficiently wide, I believe. Apparently, a "walk-in" utility room is necessary. But why actually?
