While all our sales are non-refundable, we do offer a one-time Exchange Program within three months of your original purchase date. If you discover that you are unable to build the house design that you have purchased, we may permit you to choose an exchange plan from our existing catalog. You will be required to pay the difference if the cost of your selected replacement plan is greater than the originally purchased plan. The difference in cost will not be refunded given the amount of effort required by My Modern Home in assembling and issuing your drawing packages.
