Well in which case…off you go!
We too have done up several houses, which is why we wanted a project like this. However it was certainly more complicated doing it in France…administration and public services are not there to help you, and simple things like sorting our new electricity connection took months. There seems to be less of a culture of renovating houses (building a new one is much more popular) so a lot of things I took for granted are not available.
Final thought, garden maintenance services are phenomenally expensive, so be careful about the amount and complexity of land you buy. There is a reason why many french people had dead flat, square gardens with not much in them as most economical to mow with a ride on mower.
