Build a Cold Frame Using Old Windows. You'll only need basic tools to build a cold frame.
Since the cold frame will be pretty large, it's best to build it outside or in a garage, or you may not get it out the door... A hand-held drill (cordless or corded) A miter saw (powered is better, but you could do it with a hand saw and miter box) A jig saw, circular saw or table saw (really, anything that can cut large sheets of plywood) A screw driver A Tape Measure A marking implement of some sort A paint brush.
