Hi,
He should return the downpayment upon demand. If not, you'll have to sue him in small claims court if it is within the money limits of the court or retain an attorney to sue him for it. Hopefully it won't come to that. Alternative if you need to move: assign/sell the contract (if allowed in the contract) to someone who can wait for the completion of the unit. Maybe you can make a profit :-).
