Power wash to remove any debris or growth, perhaps use a concrete stain to colour them, use a separator, such as grass, treated wood or pebbles to create a pattern and re-lay the slabs. Use the edging to create a raised flower bed along the back or sides, and you might think about some adding a few sections of trellis to bring some vertical height to the walls and break-up the walls. An evergreen type of climber would provide colour and fullness both summer and winter. A few shaped pyramid junipers might do that as well, but they do attract mosquitos.

I have porcelain and Indian Sandstone in my garden. Porcelain comes in different R ratings (R9 - R13). The higher the rater the better the non slip effect. Mine is R13 and is completely non slip even in the pouring rain. The drawback is the non slip finish means it holds onto dirt and can get grubby (mine does), so rather annoying! Never have the R13 indoors as cleaning it is difficult. The sandstone is a natural finish that comes in a riven rustic finish and a calibrated finish which is more modern and straight edged. It comes in many shades from grey, beige, pale green etc. I’m not suggesting what you choose but a paving that is difficult to clean is a right pain!

Celine there are loads of porcelain finishes from the palest of white to wood effect and dark grey. I would avoid white as it could show the dirt a bit too much! Here’s some more images of porcelain. I don’t know what the paving is in your pics but possibly porcelain?

Hi there, I agree with Sarah. The crazy paving path does look like it is coming appart, and therefore I would try and replace that too. I would also make it a bit wider than it is at the moment (a bit more comfortable to walk on, especially if carrying garden tools etc.). You could use bricks to match the short wall that you have there or maybe bound gravel with an edging of bricks would also look charming. I would also line it with some planting, maybe some lavenders, cat mint or something else aromatic. For the gravelled area that you have at the moment, it looks like it is your seating area? If this is the case I would go for a more solid type of paving with a naturalistic look such as sandstone or yorkstone, and maybe have a brick edging as well just to connect the different spaces of the garden.
