Picture of Lego Windmill
This is a guide on how to build a windmill out of Legos without buying a Lego windmill kit.
It's a lot cheaper to make a make shift windmill out of stray (so to speak) Legos than to buy a whole kit to build one. This will be a basic windmill nothing too fancy, you could spice it up with special Legos your kids have laying around. The whole thing is made with practically only 2x4 lego blocks, the most common ones there are!

Step 1: The Base!

Building the base of the windmill is pretty easy and there are hundreds of ways you could do it, you may even have a base that would work laying around built already! First I found the biggest lego base I could find and added more to the side of it. To make it sturdier I made sure to criss cross the legos when building the base to give it more stability.

Step 2: Making it taller!

Next, we make the windmill taller and start narrowing it out some. We do this by making a box at first then adding to the box like a pyramid, if you check out the photo's below you can see what I mean. When your satisfied with the basic height, or when your ready to make your tower, cap the box off with a thin lego that covers it all as seen below.
