When we had a smaller garden (well, a tiny back yard really, no bigger than our dining room) we had a similar problem - we made a circular paved patio with a hole in the centre for the leg of the rotary drier - when it was not being used it was taken down and put in the shed, otherwise the garden couldn't be used. As I said, it was a small garden and the washing did occasionally get 'involved' with the runner beans, but we managed to keep the rambling rose away from our undies.
Now we have a bigger garden which had the usual linen posts and line across the lawn. We've removed this and had a sturdy post with a metal ring incorporated in the fencing - two of these http://www.ebay.co.uk/itm/VILEDA-CORDOMATIC-IN-OUTDOOR-WASHING-CLOTHES-AUTOMATIC-RETRACTABLE-LINE-15-METRE-/360662072814?_trksid=p2054897.l4275 are fixed to the house wall, and when the lines aren't being used they are retracted and we can use the whole garden without being garotted. The only thing we had to consider when planning the rest of the garden was the siting of large shrubs, so they're not too close to where the washing lines are when they're in use.
Hope that gives you some ideas
