Metal building with living quarters rough in

[Jdm8460]

Metal building with living quarters the panel is on the outside and about 20 feet away from new build that will be 2x6 what type of shielded wire do I need to run and will it need a junction box to convert it to romex? Would it be best to add a secondary panel inside of the new build I would prefer not to since I have plenty of space on existing panel
New living quarters consist of 1 bed one bath living room and kitchen

My advice would be to add a sub panel inside. That would make the wire pulling a whole lot easier than coming from the outside panel. Use the outside panel for the HVAC unit, and an outside building. Hope this helps.

Thanks for the input I will start ordering supplies for sub panel

Good luck with your project and I’m starting in 2 weeks to install the same thing as you.
