Houses in Darkfall Unholy Wars are located in villages and offer various perks to the owner. All player houses are located in villages.
To obtain a house you first need to find a house deed.
House deeds
House deeds can be found in chaos chests, treasure map loot and may even be dropped from monsters.
Once you have found the deed you will need to locate a village with an empty house slot of the same type as your deed. To erect your house, approach the house slot and double click the deed in your backpack.

Once your house is placed you can add decorations to it that you will find in similar places as the house deed.

You will also want to place a door on your house to make it safer. Doors can be destroyed but this takes a long time.
