Level 23 buildings???

A few of my lads including that of myself are level 22 in a lot of our buildings. would it be possible to get an added few levels into the game?, as no doubt we will max out at 23 if you just up it one level

Kind regards

we should get to level 30 building instead of 23.
I agree we could do with a challenge other than snack and goodies shops I've only got the guild hall I can upgrade once my finance office is complete which is currently on upgrade to 22
