Value of a builders mistake
	
	
		I am currently building with a large builder and have run into SEVERAL issues. The biggest one is that I selected and elevation that significantly altered the entry-way to my future home. The change has altered the appearance and is severs feet narrower than I was expecting. After reading through the contract and paperwork I could technically get out of the home because they did not disclose this info to me. My question is, I am going to propose they do something to "make me happy" in a sense, so how do you put a value against that?  They cannot alter the entry, so how would you propose a value (money towards closing, additional upgrades at no cost, etc.), any suggestions help.
Thanks!
