Thanks for all your replies guys!
Does anyone know how cambio de uso fits in to all of this? would it be encorporated into a major works licence or seperate? Ive heard it can be costly and time consuming (if possible at all!).
Also does any one know if the ayuntamient would have any problems about us doing the work ourselves, in our spare time, not as registered professionals?
Coming from england i cant help but think why does the Spanish government makes it so expensive to renovate – it seems like there is no incentive for renovators (spanish or foreign alike) to restore and guard Spain’s old building (ie heritage!). I mean i could undertand if the ayuntamiento wanted to know exacty what we are doing, but taking a cut of the construction costs….
