According to your request I will recommend for you an English-speaking renovation team, and a designer or an architect who is comfortable to work with.
If you wish to buy a plot of land, and build a villa or modify the façade of the existing house, you need to start by taking advice from a local architect, who can explain the rules of French urbanism and the opportunities involved.
Many people can be worried when they think about renovation in a foreign country. Sometimes they are ready to pay more for a property that’s ready to live in.
However, I always advise our clients to choose, first of all, a location and a view, and if are you lucky enough to negotiate a prime location for a reasonable price, I will be very happy to organise any renovation or construction works for you with a team of your choice.
