I tried drying linens and clothes outside the first time I moved from an apartment (with strict controls on what can and cannot be seen on the balcony) to a single family home. I quickly stopped because there was so much dust that would accumulate on your freshly washed clothes in the time they were hung outside. That's not to mention bird poop or feral cats deciding to do some stretching on your sheets.
You need a sun room.
I agree. I like my sun room to be upstairs of the smoking lounge, but next to the library.
That's no longer "basic low tech from centuries ago" any more. Centuries ago there wasn't transparent glass, only colored glass (think stained glass in an old church).
