How much will a basement conversion add to the value of my house?
In virtually all cases a basement conversion will add to the value of a property. However the exact increase in value will depend on a number of factors such as local property prices, the size of the basement, and the quality of fittings and decor in the basement.
In areas where property values are particuarly high, such as Central London, the increase in property value can be considerably higher than the cost of converting the basement.
Even where property values are lower, creading additional living space by converting a basement can make financial sense when compared with the cost of moving house (stamp duty, legal costs, estate agent's fees, etc...).
