A building that’s less likely to suffer damp or water damage is always more attractive than the alternative. Tanking would reassure any potential buyers that the below-ground level of your home does not pose a risk to the rest of the house. In addition, you could also consider converting your tanked basement or cellar into a usable room.
When you create additional living space in your home, this usually results in an increase in value. You could use your converted cellar as a new living room, a games room or even as a home bar! The possibilities are endless.
