¶1Appellees brought this action against appellants to recover an alleged balance due on a building contract. Issues were formed on the complaint in four paragraphs by an answer in general denial. Appellants also filed a counterclaim upon which issues were formed by general denial. A trial by jury resulted in a verdict in favor of appellees on their complaint and against appellants on their counterclaim. Appellants’ motion for a new trial was overruled, and judgment rendered on the verdict.

¶5The action of the court, in giving of its own motion, instructions Nos. 3 and 5, and refusing to give appellants’ instructions Nos. 3, 4, 6 and 7, involves but one question. The court by its own instructions Nos. 3 and 5, stated to the jury among other things, that under the issues it should find for the appellees, in the event it is proven by a preponderance of the evidence “that they have substantially complied with the provisions of the written contract upon their part to be done and performed, and such oral modifications thereof as may have been made by the parties, or that the dwelling house wás accepted, by the defendants as sub*272stantially completed under such contract and such modifications.” (Our italics.)
¶6The appellants requested the court, by their instructions Nos. 3, 4, 6 and 7, to state to the jury in substance, that if it found from the evidence that the appellees had failed, omitted or neglected to perform any of the work called for in their original contract in a workmanlike manner or that the materials used were not reasonably suitable for use in buildings of the kind described in the contract, or if it would require the expenditure of money on the part of appellants to remedy any such work so performed in an unworkmanlike manner, or to replace such unsuitable material, appellees could not recover on their complaint.
¶7Appellants admit that the court’s instructions correctly state the law in the abstract but claim they.are not applicable to the issues presented by the complaint in this action ; that the complaint presents an issue that requires substantial performance and the instructions permit a recovery on a waiver of full performance and an acceptance of the building.
¶8Without considering the correctness of the instructions tendered by appellants, it appears from a reading of the instructions given that the jury was not misled as to the issue presented for its decision. The complaint alleges the execution of a written contract to build a house according to certain plans and specifications. It also alleges an oral contract ,for certain specified extras, and that after the original contract was entered into, the plans and specifications were changed in many respects, details of which are fully alleged; that appellants agreed to pay for the extras and the changes were made at their request and mutually agreed upon; that appellees “performed all of the conditions of said contract on their part to be performed”. These averments do not show that appellees were seeking to recover on part performance of their original contract and a waiver of performance of part of the obligations assumed *273by them, but that they were suing to recover the balance due on the contract as modified and for extras authorized by appellants. The detailed changes and modifications alleged in the complaint, if proven, showed that appellants had abandoned or waived performance of some of the provisions of the original contract and by oral agreements had so changed the plans as to make full performance of the original contract impossible. The averments of performance on the part of appellees can not reasonably be said to mean performance of all the provisions of the contract as originally made, but evidently meant, and must be held to mean that they had performed all the obligations resting upon them under the whole contract shown by the averments of the complaint. The latter part of the instruction complained of in substance told the jury that if the defendants had themselves accepted the house as substantially completed under the original contract and the subsequent modifications thereof, that was sufficient proof of performance on appellees’ part to entitle them to a recovery.

¶10The judgment seems to be just on the merits of the ease and no intervening error is pointed out which will warrant a reversal. §§407, 700 Burns 1914, §§398, 658 R. S. 1881; First Nat. Bank v. Ransford (1914), 55 Ind. App. 663, 104 N. E. 604, and cases cited.
¶11Judgment affirmed.
