Or Kenya top bar hive. The nice thing about the top bar hive is it allows the bees to draw their own comb (no foundation forcing them into drawing an unnatural cell size, people made foundation has a larger cell size than what a bee would naturally make, the idea was to make bigger bees that can produce more honey). However, you can also do this with the traditional Langstroth hive which is what I do. The foundation you are going to buy is made from wax produced by the big bee operations. These wax are full of chemicals used to treat the hive; bad stuff. With the top bar hive you do need a starter strip of some sort to get them drawing the comb properly (if you don't have a starter strip as a guide they can draw the comb perpendicular to the bars and you are then screwed, no managing the hive then). If done right and the bars are made to honor 'bee space' (a hugely important thing), the bees will draw beautiful comb that is only attached to bar and not the sides.
