I think you may be underestimating the amount of power needed to heat 1000+ gallons of water in a pond in a shed. I would expect you might need 3000 watts or more of heat, not to mention filtration pumps. This could end up costing over $100/month (or more!) to run pretty easily. Of course this all depends on what the temperature is like where you live.
I don't mean to discourage you, but you do need to consider this.

If I lived in one I would have a t.v, fridge, heater, fan, my xbox, and fish tanks on the first floor. A bed and another t.v and a bed on the 2nd story.
