But inquiring minds have to ask - where are most people getting dressed / undressed each day?
Personally, I would want a laundry in proximity to the bedrooms in a house but I understand we all have our preferences. We currently live in a one story home but our previous house was a four level spilt. The laundry facilities were in the basement and he bedrooms on the top floor of the split. That seemed to be quite the pain (especially since we did NOT have a laundry chute....)
I get dressed/undressed each day upstairs. Not sure what that has to do with laundry as dressing/undressing doesn't take much time out of my day. Every morning, after dressing, I take the dirty clothes downstairs to the laundry room and, as I spend the day down, I wash, dry and fold/hang the clothes moving back and forth from kitchen, den, etc. doing household chores, watching TV, or whatever. I can hear the chime when the washer stops and it's just a few steps to the laundry room to move the clothes to the dryer. I can hear the buzzer when the dryer stops. Most of my clothes I hang to dry as soon as the washer stops and have racks to do that in the laundry room. Other times, I go back and forth to take some clothes out of the dryer early and hang them to finish drying. Why would I want to run up and down stairs multiple times to do that? Clean clothes are carried up whenever I do need to go up, but always when going up to bed. They are put away then. Just makes sense to me. But you are right, personal preference.
The best situation we had was when we had a master bedroom down and the laundry room was as one entered the house from the garage and also had a door into the master bedroom closet. That was nice. Right from the dryer to hanging or tucking in drawers in the closet.
Four levels would be really hard, I agree, but I still wouldn't want to have to spend hours upstairs doing laundry when the hub of the house where I spend my day is down.
