In older french properties is dampness a problem to be treated or a fact of life which is minimaised by adequate ventilation? I previusly owned an old house in UK and despite an injection damp course, it would still smell damp if left closed up for a period of time. Peter

If this is covered in an FAQ please point me at it.....A friend has seen a building 'a renover' in about 1000m2. He would like his renovation to effectively double the size of building. Are there national or regional limits to what he can do? How far should he / can he check feasibility before making his offer? Or is it all down to getting on the right side of the Mairee? Anyone had experience of similar? TIA Peter
