We have a nearly 2 year old dd and have a serious amount of building work going on starting tomorrow! We're having several walls knocked through, a new kitchen put in (building works moved forward so will have no kitchen for at least a weeks as kitchen is ready for original date and takes a week to put in) and we had previously organised to stay at my in laws.
They were okay with this, said it was fine and we told them we would pay to stay, buy our own good and do our share of cleaning up.
We've called up today after telling mil a week ago that our building work had been moved forward to this week rather than next and mil was fine with it. She was happy to have us stay and looked forward to seeing us tomorrow, about to get off the phone and fil goes apeshit in the background basically saying he hasn't ever agreed to this (he had), we don't live by their "standards" and that he doesn't want us staying until he's had a proper sit down with us and outlines the "rules".
For gods sake, we aren't strangers, we know the rules! The child only eats in high chair, she doesn't touch anything she shouldn't, nappy changes happen only on tiled floors with a nappy mat, we tidy up all mess immediately and clean up after ourselves- we get this is their rules their house it's fine!
Fil then tells us we are dirty (we really aren't, our house is pretty spotless tbh but dd does make mess constantly so toys do send up on te floor) and that we will be their for months, not two weeks.
We now have nowhere to stay because dp is devastated that his df has basically called us all dirty and made it very clear we aren't welcome in his own childhood home.
I do like my in laws, like all of us they have some awkward traits but we try and get along best we can but nobody and I mean nobody feels at ease in their home. Fil has blatant OCD and it is cleaner than most show homes but I think if rather stay their unwelcome than at a building site with no kitchen with a toddler.
I reaaaally don't know what to do here 
Sorry for the rant!
