A beehive assembly that includes first, second and third stacked box-like hive sections that are securely interconnected by specially designed corner brackets. An important feature of the beehive assembly resides in the provision of a novel temperature control apparatus that is connected to the first box-like hive section for controlling the temperature of the interior chambers of the bee hive assembly. The temperature control apparatus here comprises a thermoelectric plate, an electrical power source operably associated with the thermoelectric plate and a plurality of fans for circulating the heated air within the hive.
