Nope, sorry, just pick one adept builder (PICK THE ONE WITH MOST SKILL) to focus on and repeatedly put him back to fixing huts again and again until he becomes Master. You could also make the exercise potion repeatedly and get him/her to drink it and hope that s/he gains building experience each time.
Highlight below for SPOILER potion
Black orchid + tiger lily + cactus = exercise
