Please don’t do it, fashionable or not.
It’s eco-unfriendly for a huge number of reasons:
- the production process - it’s plastic and it isn’t even recyclable.
- it kills the wildlife - absence of worms and critters keeps away birds as well.
- it overheats in the summer, so it may need watering to keep cool!
- micro plastics are washed off it into the underlying soil.
- any leaves, etc that fall onto it won’t decompose, so you will need to keep it clean (Some people hoover it!)

Paving will also overheat and prevent water flow.
Keep your lawn, accept that it won’t be perfect but it will be much better for the environment. I personally don’t even like the too-uniform look of a fake lawn and prefer the patches and mud of a real one!
If you like it, clover is a nice alternative which will look less patchy and will need less maintenance and mowing.
