Mr. Miche?l Mahon:

As outlined and specified, we can amend or reflect up-to-date costs but it is important to note that the costs are calculated on an average basis. There are many different types of houses. We have clearly set out that we took the case of a house with a partial brick elevation. There will be houses with stone elevations. One cannot capture every house type in this exercise. It is very difficult to answer the Deputy's question, as he will appreciate.
