Mr. Kevin Kelly:

This is something the individual house owners have to deal with. Ideally, in this scenario, people would work together but, theoretically, there could be a scenario where one house is being done and the other house is not. We can certainly get the information on the breakdown between house types and, even in my own planning lists, quite a few that I have seen are typical estate houses, and are semi-detached and so forth. We can get that information.

There is no co-ordination mechanism at the moment. If there are ten houses in an estate, they could all be having work done individually as opposed to there being some sort of collective mechanism because it is a private issue for the homeowner.
