[White Out 403]

Hey all. I'm about as useful as tits on a boar, to quote on my favourite movies, and I need some advice. I have an unfinished basement and we won't be able to afford to finishing it for a few years at the least, but it's now become my home office. I installed a couple of baseboard heaters but they're not powerful enough for the basement which is around 800 sq feet with high ceilings.

So, what I need to do is get creative to keep myself from not freezing. I thought of some sort of temporary walls? Is that something people do? What kind of possible solutions are out there that are feasible do to divide off an area but not involve framing and drywalling?
