On November 17, 2014, the registration for the preservation of a single house was made on the part of a single house.

Under the contract, the construction cost shall be KRW 79,000,000, but the defendant directly executes the construction cost of KRW 3,000,000,000 and the 1,000,000,000, which is paid by the plaintiff, and if the construction exceeds the above amount, the plaintiff shall bear KRW 1,00,000.

The Plaintiff was paid KRW 60,000,000 as the construction price by the Defendant.

[Ground of recognition] Facts without dispute, Gap 1 through 3, and the purport of the entire pleadings is that the defendant is obligated to pay the plaintiff the balance of the construction cost of KRW 15,000,000 (the construction cost of KRW 79,000,000 for the contract - the amount of KRW 4,00,000 for the direct construction of the defendant - the amount of KRW 60,000 for the payment).
