Hi, Here's a link to a thread with the same question. Interesting read for you, I think. I would agree with floor first. Have you asked your kitchen fitter for his reason to say floor last? https://www.houzz.co.uk/discussions/3661752/floors-before-or-after-fitting-kitchen-units Good luck with your project. It can be stressful. But worth it in the end.

Schluter, have lots of possible solutions for the above. http://www.schluter.co.uk/movement_joints.aspx

the layout and planting ideas are great, thank you. the garden is south facing, so the evening sun is on the triangular area nearest the front door. I put bamboo screening up but there's a footpath the other side of the metal fence, and it got vandalised so often that I gave up. ditto the few fence panels we had put up against the metal fence to give us some privacy. it's council and of course they refuse to erect a decent fence, or facilitate some sort of system where we pay them back in instalments. I dont expect handouts, I'd have a 6' high fence put up tomorrow if I could afford it. hiring a skip is also out of my budget, so I've gradually been taking stuff to the tip or burning it. I have kids and pets including chickens, and although I'd like to think I'll grow some veg in the raised beds, I know I'll never get round to it! the sheds: one small one is a potting shed, the other small one in the corner chicken run is storage, and the big one is supposed to be a workshop but is currently crammed with stuff that needs sorting and storing or chucking, including all my tools, garden tools, kids toys, camping stuff, etc etc. I'm sure you get the picture! there are 2 greenhouses and umpteen raised beds, stacks of bricks, wood, bits of shed panelling, old Windows etc, because my husband had lots of plabd for the garden and did loads of growing veg etc, but never got round to finishing anything. in his defence this is Wales, it rains all the bloody time, and of course there are never enough hours in the day. however, we have recently separated, so I now find myself staring in horror at the whole overwhelming project, scratching my head, wondering where the hell to start, and then closing my eyes and pretending it's not there.

I think you should ask the tiler for his advice! If the kitchen has not already been fitted I personally think you would be crazy not to tile the floor first. You've already highlighted the biggest problems with doing it after the units have been fitted regarding the moving of appliances. I have to suspect that your kitchen fitter just wants to get on with the job, get paid and get out, leaving the tiler to cut and lay tiles in a more difficult situation (at more time and more cost to you).
