The Beehaus is the most modern beehive having been launched in 2009.
It is based on similar principles to a Dartington.
The top-bar or Kenya-hives were developed as a lower-cost alternative to the standard Langstroth hives and equipment.
They are used by some devotees in the United States, but are much more popular, due to their simplicity and low cost, in developing countries.
Top-bar hives also have movable frames and make use of the concept of bee space.
