Tbe defense relied upon by defendant to plaintiff’s recovery upon tbe cause of action set out in the complaint, is that plaintiff has not performed bis contract with defendant, in that be has failed to furnish plans and specifications for the work contemplated in accordance with tbe contract. Defendant alleges that it was expressly understood and agreed that the plans and specifications to be furnished by plaintiff should be so drawn and prepared that tbe cost of construction in accordance therewith should not exceed $17,000, whereas tbe lowest bid submitted for tbe work in accordance with tbe plans and specifications as furnished by plaintiff exceeded $22,000.
Tbe contract in writing, between plaintiff and defendant, consisting of tbe proposal and acceptance, does not provide that tbe cost of construction in accordance witb tbe plans and specifications which tbe plaintiff agreed to furnish should not exceed tbe sum of $17,000— indeed, there is no reference in tbe written contract to any sum as tbe maximum cost of tbe work contemplated. The proposal contains tbe following clause:
“Tbe construction work contemplated shall be as approximately outlined in the preliminary sketches and comprise remodeling tbe present bouse witb tbe necessary additions.”
Defendant agreed, by bis acceptance of plaintiff’s proposal, to pay to plaintiff for bis services in acting as defendant’s adviser, in furnishing plans and specifications for tbe work contemplated, in drawing tbe contract, and in supervising generally tbe construction of a block of six stores to replace tbe present first floor and two apartments to occupy tbe second floor of defendant’s present residence, corner Road and Main streets, Elizabeth City, N. C., five per cent of tbe construction cost of said building.
There was evidence to tbe effect that prior to defendant’s acceptance of plaintiff’s proposal, as a result of negotiations between them, plaintiff prepared and submitted to defendant preliminary sketches of tbe *169work contemplated, and tbat after full discussion plaintiff estimated tbat tbe cost of construction in accordance witb said preliminary sketches would not exceed $17,000; tbat defendant informed* plaintiff tbat be would not undertake tbe remodeling of bis building unless tbe work could be done for a sum not in excess of $17,000; tbat plaintiff made and submitted figures witb tbe preliminary sketch showing tbat tbe cost would not exceed this sum; tbat after tbe plans and specifications bad been prepared and submitted to defendant by plaintiff, plaintiff assured defendant tbat tbe work could be done in accordance witb said plans for a sum not in excess of $17,000; tbat thereupon, by means of advertisements, bids were sought for said building in accordance witb said plans and specifications as furnished by plaintiff; tbat tbe lowest bid secured for said work exceeded tbe sum of $22,000; tbat this bid was rejected by plaintiff, acting for defendant, and tbat thereupon defendant refused to accept said plans and specifications and declined to proceed further witb said work.
There was evidence from which tbe jury could have found tbat tbe entire contract between plaintiff and defendant was not contained in tbe written proposal and acceptance. Tbe terms of tbe contract, which defendant contended were not included in tbe proposal and acceptance, and which tbe parol evidence tended to establish, do not contradict, vary or add to tbe terms of tbe contract as contained in tbe writing. If, therefore, tbe jury shall find tbat tbe entire contract was not in writing, defendant may by parol evidence establish the terms of said contract, which were not included in tbe proposal and acceptance.
Tbe plans and specifications which plaintiff proposed, in writing, to furnish for remodeling defendant’s building are not definitely and specifically described; tbe said proposal leaves it doubtful or uncertain as to what tbe plans and specifications should provide witb respect to tbe building; it is provided tbat tbe construction work contemplated shall be approximately as outlined in tbe preliminary sketches which had been submitted to defendant by plaintiff. Defendant may therefore show by parol evidence what tbe agreement was witb respect to said plans and specifications. If plaintiff agreed to furnish plans and specifications for work which would not cost to exceed $17,000, defendant may show this agreement, not to contradict, vary or add to the terms contained in tbe written contract, but to make certain what plans and specifications plaintiff agreed to furnish in order tbat tbe jury may find whether those furnished were in compliance witb tbe contract.
“We have no disposition to modify or disregard the settled rules, intended for the ‘protection of the provident,’ and not for ‘the relief of tbe negligent,’ which prohibit tbe admission of parol evidence to *170contradict, add to or vary tbe terms of a written contract, even where a part of a contract is in writing and a part is in parol, Moffitt v. Maness, 102 N. C., 457; but we must adhere to the long line of decisions which hold that where the contract is not one which the law requires to be in writing, and a part is written and a part is not, evidence of the unwritten part, if it does not contradict the writing, is admissible for the purpose of establishing the contract in its entirety. Twidy v. Saunderson, 31 N. C., 5; Manning v. Jones, 44 N. C., 368; Daughtry v. Boothe, 49 N. C., 87; Braswell v. Pope, 82 N. C., 57; Cumming v. Barber, 99 N. C., 332; Palmer v. Lowder, 167 N. C., 333.” Adams, J., in Henderson v. Forrest, 184 N. C., 230.
“It is a well-established general rule that if the parties reduce their entire contract or agreement to writing, whether under seal or. not, the court will not hear parol evidence to vary or change it, unless for fraud, mistake or the like; but if it appear that the entire agreement was not reduced to writing, or if the writing itself leaves it doubtful or uncertain as to what the agreement was, parol evidence is competent, not to contradict, but to show and make certain what was the real agreement between the parties; and in such a case what was meant, is for the jury, under proper instructions from the court.” Davis, J., in Cumming v. Barber, 99 N. C., 332.
We must hold that the instruction of the court to the jury upon the first issue was erroneous. The assignment of error based upon said exception is sustained.
It may be conceded that there is no evidence from which the jury could have found that the agreement with respect to the maximum cost of the building was omitted by mutual mistake of the parties; defendant’s defense, however, is not dependent upon' the reformation of the written contract as prayed by him. Plaintiff cannot recover in this action unless the jury shall find that he performed his contract with defendant by furnishing plans and specifications in accordance with his contract. If plaintiff agreed to furnish plans and specifications for remodeling defendant’s residence as outlined in the preliminary sketches at a cost not to exceed $17,000, and the cost of doing the work in accordance with the plans and specifications prepared by plaintiff, will exceed the sum of $22,000, plaintiff cannot recover, for he has failed to perform his contract. It is not contended that plaintiff as architect guaranteed that the cost of construction would not exceed $17,000, but that he agreed to furnish plans and specifications in accordance with which the building could be done at a cost not to exceed the sum of $17,000, and that he has failed to furnish such plans and specifications. See Feltham v. Sharp (Ga.), 25 S. E., 619.
*171The exception to the 'introduction as evidence of a copy of the Kidder-Nolan Handbook, 17th edition, cannot be sustained. It is expressly provided in the contract that this handbook shall be authoritative on any question arising under the contract. If plaintiff has performed his contract with respect to the plans and specifications, and the work was abandoned by defendant, through no fault of plaintiff, plaintiff is entitled to recover, under the contract, a sum equal to 60 per cent of the reasonable cost of doing the work in accordance with the plans and specifications furnished in compliance with the contract.
For the error in the instruction upon the first issue, there must be a
New trial.
