What to do with an empty paved double drive to make it more garden-like?

[daffodilstreet]

So our diesel car will be kicking the can soon, when it's tax expire - because we live in the soon to be extended ULEZ.

this means we will have a lovely empty double driveway in front of our house! It was done by the previous owners only a couple of years ago so it's very neat and tidy.

We want to maintain the driveway (although we would prefer a front garden!), because they are expensive, and there is no street parking for when we have visitors.

But we want to make it as garden like as possible. I was thinking about putting some raised planters in, ones on legs so that the base isn't touching the ground (to reduce moss or damp).

Has anyone seen any ideas that I might be able to use?

How about with wheels so they could be moved as needed?

Wheels are a good idea. With planters and pots you want them as big as possible to maximise water retention - which then makes them very heavy if you do need to move them.

Is it completely paved? Or gravel?

Could you dig it up and do a beautiful gravel garden with those support grid things for cars to drive on and then it could be a garden most of the time but would double up as parking when you need it? That's what I would do.
