What is a build over / agreement?
Where a property or part of a property is build over a public asset, such as a water main or sewer, it is advisable to check that permission has been granted in the past for the building or extension to have been built.
If you have an asset under your property, there are certain risks associated and the responsibility lies with both the property owner and the statutory undertaker to ensure that the risk to the assets are minimised. If, for example the weight of the building causes damage to the asset underneath, it may be possible that the property owner is held responsible, and similar if a broken asset causes damage to foundations, it may be that he statutory undertaker is held responsible. These cases are extremely rare but can cause problems.
