Integrated

An integrated bat house is a bat house that is part of the building structure. The entrance can be by the roof or on one side of the building. The bat house can be partially or completely in the building, but with no access to the rest of the building. This type of bat house generally gets better heat retention. Dimensions: medium to large size.

Condo

The condo model is a large-scale construction that can accommodate several thousand individuals. Its large volume generally provides a great heat retention. More expensive and complex to build and install, this type of bat house is more often used by environmental organizations as a conservation tool.
