Heating systems

[Will Bert]

Hello everyone I'm working on a project. I'm having 2 open livable loft space. My contractor suggested that i put ceramic heated tiles which I will on the ground level but the upstairs I want a more rustic look as the area is populated by artist. So I'm having trouble deciding what type of heat to put. 

1. gas heat -downstairs heated floor and upstairs baseboards

2.25,000 - 30,000 btu AC heat and cold air units 

3. Gas heater with a aluminum duct going across the loft with fans to blow the heat down

4. ANY SUGGESTIONS ARE WELCOME ...PLEASE HELP

trying to post pic's to give an idea but it won't let me ....
