I am having the same problem. My builders are adept - 6 of them and they are now 64 yrs old and since they were 39 I have been dragging them back to the huts and repairing them and even though it says the builder has improved at construction - the line has not moved. I have built every hut, cleared the rock of leaves, cleared the rubble, repaired the bath. There is nothing else I can do to encourage improvement other than repairing the huts and I seriously don't think that 25 years of improvments to the huts can result in no improvement but it appears that way.
