SLOW DEATH OF A LAWN

My lawn has suffered terribly this winter.  It's full of weeds, yellowing grass, and balding patches.  It's a far cry from the beautiful, pristine, lawn that I had only a year or so ago.  It has to go.  It's far too much work for me constantly feeding, aerating, putting down weed killer, not to mention mowing, and I have to think of my cat and all those chemicals.  The problem is, I love a nice lawn and it seems such a pity to get rid of it but I have in mind, perhaps, a path through herbaceous plants.  Lawns are high maintenance, if you want a decent one, and I think the occasional weeding is far less labour intensive than dragging a lawn mower out of the shed once or twice a week, picking up all the cuttings, and trimming the edges around the border and the stepping stones.  You can see the difference in the before and after images below.  What a difference a year makes!

I just don't think I can bring back the lawn below to the above standard without starting from scratch.  One of the big problems in the quality of the soil below the grass.  In areas, it's less than an inch deep and below that is so much sandstone that it is almost impossible to dig up and impenetrable with a fork.  I wonder if at one time the land on which my home stands was once fields and that there was a wall which has been bulldozed and spread across the ground and then soil spread on top of that.
