TBH - expanding the hive question

[Boom Buzz]

My friend has a TBH that can take a medium frame (depth and width) and the length is about equivalent to 3 langstroth supers, so it can take maybe 30 frames.  He is thinking about expansion plans for next year if the colony builds fast and his idea is to use medium supers as a second level to give the bees additional space and to prevent swarming.  Is this a reasonable approach?  If not, then how do you address additional space and prevent swarming with a TBH?

Thanks for any comments

BTW - 40 miles north of Denver and had a 12 inch snow last week, this week days in the 60's, bees are flying and bringing back pollen...

I have seen some people create supers to add on top of tbh's.  it is done.

Mostly, TBH's space is managed by keeping an eye on the honey bar section and making sure they do not get honeybound. So by taking a bar or two here and there and by spacing out the brood bars by placing empty bars in between ( one empty space between two) can help much if preventing swarming is what you are trying to accomplish.
