I have what Palmera termed "the Spanish Builders Contract", which I received around 10th March 2003. Does this refer to it being a "State Subsidised Dwelling" or something more sinister?. Please elaborate.
Regarding the extras, you're under no obligation to accept or pay for them. If you accept them, it has to be at the builder's cost, unless, out of the goodness of your heart, you want to contribute towards the cost. If not, tell them to take a hike.
