No Lawns

I hope these type of requests are allowed here. Otherwise just let me know and I'll remove my post.

I'm soon moving to a new house and it has a little garden area of 5.5 m wide and 4.4m long. And surrounded by a tall hedge (that I don't want to remove)

At the moment, as you can see on the pictures below, it's all tiled. I initially intended to remove about a third of the tiles and make a mos, clover and wild flowers lawn that my cat and dog can use now and then. Then maybe make some tall planteres for wild herbs from stacking the removed bricks up in a square and adding some wood planks.

But now i got the idea of asking you guys if you have any better ideas for how to use this space for a little sanctuary for me and my pets. I'd love to see some inspiration, sketches or ideas from you on how i get more use out of this space. Maybe removing the tiles is not the best idea?

I live in Denmark so the climate is a bit mixed. I'm not a big gardener type of person so something simple that mostly takes care of itself is ideal. Lavenders, sage, oniongrass types of herbs and Viola tricolor and wild flowers for easy and pretty colors.
