Affordable solutions for working on the car in this weather

Morning folks. The weather gods hate me and seem to only rain when I've got a day off so I'm unable to sort the bits on the car I need (taking doors apart, bleeding brakes - stuff which needs dry weather).

What's everyone's affordable solutions for working on the car in the driveway when it's raining? My driveway is outside the living room window so I can't build a garage - that would also take me ten years to save for lol. I did look at this like this but these are well out of my price range.
