Clothes horses - heated ones are useful
Outdoor clothes line
Enough clothes so you're not immediately short of underwear if you can't do washing a particular day.
Designated DIY / work clothes that are allowed to get stained because they're only used for messy jobs
Designated clothes for messy animal care.
Aprons for cooking / messy arts and crafts
Gaiters for grown ups / rain suits for small children who play in mud
And the most important one:
Only washing clothes that are dirty / smelly. Unless either of you is incontinent or suffering horribly heavy periods or you have a tiny machine you shouldn't be able to generate a load of washing per day between two of you. There should be maybe two loads a week, which is much more realistic for drying stuff around the house.
Things that really need washing after one wear in the UK in winter: underwear, socks, tights, vests, maybe the t shirt layer, teenage + adult sports kit + muddy child sports kit. You do have to wear underwear under long johns etc otherwise they have to go in the daily washing pile.
Trousers, skirts, jumpers that aren't visibly dirty or smelly will be fine being worn multiple times without being washed.
Towels can be aired and used again - they take a while to dry.
It's manageable if you minimise washing by stopping most clothes from getting dirty and by only washing things that are dirty.
