It covers the main structure of your investment. If it were to subside, burn down or be damaged or destroyed by extreme weather, the policy will cover the costs of rebuilding or repair. It also normally covers any permanent fixtures. Do check your building's insurance policy for any exclusions: most policies will include coverage for outbuildings, boundary walls, gates, drives and paths as standard. Such policies will also typically cover the cost of temporary accommodation should the building need to be rebuilt or if there is a need to move out because the building is severely damaged—for instance, by flood.
