The Warré hive was invented by the abbot Émile Warré. It is also called “ruche populaire” (fr) or “The People’s Hive” (en). It is a modular and storied design similar to a Langstroth hive. The hive body is made of boxes stacked vertically. It uses top bars for comb support instead of full frames similar to a Top-Bar Hive. The popularity of this hive is growing among ‘sustainable-practice’ beekeepers.
The Warré hive differs from other stacked hive systems in one fundamental aspect. When the bees need more space as the colony expands, the new box is “nadired”. i.e. positioned underneath the existing box(es). This serves the purpose of warmth retention within the brood nest of the hive, considered vital to colony health.
