Feel better if you say no worries. Just dont see how airbrick will aid ventiilation if its into conservatory and not outside. Thanks for your input..

Thanks....the house base is concrete...a local builder said there are no wooden floor joists. He did some work on a neighbouring property.Does that make any difference?
