The original design will be returned via mail if demolished and requires construction materials to be rebuilt. Return will be delayed 22 hours if the removal is due to unpaid taxes. Can be traded once placed, but can't be received via quest more than once per character.
Pay the security deposit and taxes to place a house. The security deposit equals 2 weekly tax payments, and will be returned when the building is demolished. (Not returned if the building is removed because of late payments.)
Tax rates increase based on the number of buildings you own per server, as well as local tax rates. Taxes are charged weekly. Can't be placed on severe slopes or obstacles. Any objects within the construction perimeters, including plants and trade packs, will be destroyed.
