German Schmear applied without mention in contract

[Kiran Kumar]

My builder (in Texas) applied german schmear on the front elevation (brick) of our new house under contract without our knowledge. The elevation looks rustic and we don't like it at all. When asked the sales agent said he missed to put this in the "selection" sheet of the contract and apologized for his mistake via email. As per the builder the city has mandated that certain elevation needs to have this German Schmear but it wasn't brought to our attention while signing the contract and not mentioned in the contract as well.

 If I cancel the contract will I get my earnest money and appraisal fee ? 

If the builder refuses to give back the earnest money what options do I have ?
