Your disclosure statement will tell you that the floorplans are subject to change that that there can be a variance in sqftage within a certain %. You don't have much recourse unless you can prove that the developer knew without a doubt that the unit was going to be not like presented at time of sale and that the changes didn't happen afterwards. You're best option is to seek legal counsel and perhaps work with the builder and if you can't reach a suitable compromise ask for your deposit in full back and consider this a lesson learned when buying presales.
