If she had access to this useful online calculator, the wicked witch in that Hansel and Gretel fairytale wouldn't have had to settle for just a tiny cottage in the woods. She could have built herself a sprawling McMansion with proper planning, complete with a dedicated bakery just for kids.
What's particularly handy about this calculator is that it can serve up batch estimates for a full-sized dwelling, or the more compact creations you actually intend to eat at the holidays. But you know what they say, go big or go home. And for your average 185sqm dwelling, you'll need to bake up 8109 batches of gingerbread. But at a cost of just under $US58,000, it's cheaper than going with timber.
