Like many above posters, I have always had a rotary dryer, cemented in to make stable. Never had a problem, washing dries fine, I like to see it turning in the wind. It is on the small lawn near the drive, not visible from the road as it is screened by a tall hedge and a fence.
At my previous house, when the children were small, my dad fixed a contraption outside the back door for the nappies. He ran a pulley line between a bracket on the wall and one on the back of the garage. I could stand at the back door and peg out the nappies, pulling the line along as I worked. Hard to describe, but the first one pegged out ended up at the far end of the line. It was a godsend, held about 15 nappies and I loved to see them blowing in the wind!
