Most places now have a plan local d’urbanisme (PLU) in place to guide local developments, and they are usually revised every 10 years or so. They can be organised at the commune level for larger communes, or between several communes, at the com-com level and so on. Issues of sustainable development now figure much more. Because communes get money for extra population and building there has been an “inclination” to agree things that are really environmentally unsound. So the newer approaches help temper this.
So despite consultation if yours is developed at the com-com level then the wishes of one commune can be over-ridden.
