On May 5, 1923, the plaintiff executed a written lease to the defendant of the second *595floor of a building, then in the course of construction, at an agreed rental of $18,000 for a 5-year term, payable monthly in advance. It was agreed that it should become operative when the building was completed and ready for occupancy. The lessor agreed to equip it for office use, and to “furnish steam heat at his own cost for said entire second floor.”
On August 4, 1923, defendant served a “notice of cancellation” of the lease on the plaintiff. The material specific reasons assigned therefor were, the failure to partition and equip the premises as agreed; the failure to provide for the furnishing of steam heat; the permitting the floor below to be used for a pool room.
The premises leased were completed and ready for occupancy on August 15th; The plaintiff was unable to rent them for the sum defendant agreed to pay, and brought this action to recover the damages sustained by him thereby. The case was tried before the court without a jury. He filed findings of fact and conclusions of law, and entered a judgment for plaintiff for $4,470, of which defendant seeks review by writ of error.
The lease was prepared by the defendant’s attorney on a form in common use. It stated that,the premises were leased for the term of five years “from and after the......day of July, 1923,” but provided, as before stated, that it was “to operate from.the day the building now being built by first party is complete and ready for occupancy.” It was insisted that the 31st day of July was the time limit for completion of the building. The trial court said:
“These two provisions of the lease, taken together, mean simply that the parties were expecting *596to have the premises ready in July; if they were ready earlier, then the defendant company would be ready to occupy the premises, and would be liable for rent. On the other hand, if the premises were not ready by July, the defendant company would not be responsible for rent until such time as the premises were ready for occupancy. There is no ambiguity about these provisions of the' lease, and if there were any such ambiguity as claimed by the defendant’s counsel, the counsel himself is responsible for the ambiguity, as the testimony shows that the plaintiff went with the defendant’s president to the attorney of the company and prepared the lease which was signed by both parties.”
In our opinion this conclusion was justified by the above provisions. The plaintiff undertook to complete the building within a reasonable time, and the testimony shows that he did so.
The trial court found that the partitions and equipment as installed were’ approved of by the president of the defendant company. He also found that it was contemplated that special heat from the Central Heating Company would be secured, but that at the time the building was completed this-company’s mains had not reached the building. Plaintiff did install what is spoken of as an “Areola System,” which furnished the heat by hot water instead of by steam. It "was carried through the radiators as steam would be, and the lack of installation of the steam heat was, under the circumstances, no sufficient justification for the cancellation of the lease. The occupancy of the first floor was in no way restricted under the terms of the lease. Its use. as a pool room in no way violated any of its provisions.
When the plaintiff was examined as a witness, he testified to conversations had with T. L. Gillespie, *597defendant’s president at that time, in which he expressly consented to the changes made in the partitions and equipment of the premises. He was- cross-examined by defendant’s counsel relative thereto. At the conclusion of his testimony, defendant’s counsel moved that all conversations with Mr. Gillespie be stricken out because he was the'n deceased. This was the first intimation the court had of Gillespie’s death. Error is assigned on the court’s denial of the motion. It is without merit.
“Counsel camiot sit by and permit incompetent • testimony to be introduced without objection and afterwards, when it is found to be unsatisfactory, have it stricken from the record.” Simmons v. National Live Stock Ins. Co., 187 Mich. 551, 560 (Ann. Cas. 1917D, 42).
It is urged that this testimony was inadmissible because it varied the terms of the written contract. "While a contemporaneous parol agreement is inadmissible to vary the terms of a written contract, it is competent for the parties thereto “to add to, take from and modify the terms of the written agreement” by a parol agreement entered into after the execution of the contract. Kennedy v. Lynch Timber Co., 227 Mich. 269, 273.
Plaintiff’s declaration was filed- on February 18, 1925. In the bill of particulars, filed on the 27th, he claimed for loss of rental to that time. • On May 26, 1928, plaintiff moved to amend the bill of particulars by extending the claim for loss of rental to May, 1927 — in all, $5,270. An order granting such leave was made on that day. Defendant moved to vacate this order. There was dispute as to whether a written motion had been served. This motion was reserved when made to be presented to the judge trying the case. It was then renewed, *598and denied. The granting of the motion to amend was within the discretion of the court, and, as the trial was not had until several months thereafter, no prejudice justifying a reversal resulted to the defendant therefrom.
The other errors assigned have received due consideration. They present no reversible error.
• The judgment is affirmed.
