How to build Apiary in Skyrim Hearthfire
The Apiary can only be added to the Lakeview Manor in Falkreath. It cannot be added to other houses.
You should have the option to build the Apiary from the Carpenter's Workbench once you have added a door to your house.
The Apiary is found under the MISC tab in the Carpenter's Workbench
