Ever had to say you cant have tile?

Have job soon and its throwing up problems, issue im having now is floor had movement so will have to overboard with 18mm wbp before installing decoupler as tile to be layed is travertine BUT now with what id consider is belt and braces the upvc front and back door wouldnt be able to open after tiles were layed. Customers talking about puting door mat inset but im no sure if this will work and wheither tile just isnt suitable.

Anyone come across this type of issue?

can't you remove the old boards, strengthen the joists then lay 18mm ply then ditra and tile. this may be enough for door to open?

Mike, yeah this was my original plan and think it would make the difference needed but the floor will have wet ufh therfore strenghthening the joists by adding noggins unfortunatly isnt possible due to the pipes,insulation and screed. So was going to reinstall chipboard since its t&g then fix ply to it and so on.

thats a strange set up for a floor, i've heard of a few like that on here recently. i think the customer should have planned the set up better regarding the height issues

I agree, as I see it the main issues are she wants a very soft tile layed so I want the floor to be solid to avoid cracking etc and the use of wet ufh. If it was electric ufh then the floor could be strengthened as you suggested and would be a able to remove chipboard altogether and fix ply to joists.
