No, there is no recovery for sweat equity in a case like this: the court does not give you compensation for your own time, effort, etc. It is possible you may be able to sue the builder to recover any deposits or downpayment or other payments you made to them; you might also be able to recover for other monetary losses, such as if the problems in construction caused you to have to rent a place elsewhere for a time to live, or put belongings in storage; but you cannot recover for your sweat equity.
