According to the allegations of the complaint the plaintiffs purchased their property from the defendant corporation (Bobrick Enterprises, Inc.). The conveyance to the plaintiffs was not offered in evidence and we are unable to find in the record the name of the grantor; but inference from the testimony support this allegation of the complaint. According to Mr. Bobricks testimony, there was a contract (apparently with the defendant corporation as vendor and contractor) dated April 30 (no year given) under which the plaintiffs were to purchase the land, upon which the contractor was to construct a residence. The deed conveying the property to the plaintiffs was dated September 18, 1965, and the plaintiffs moved into the new residence on September 20, 1965. A week or ten days later those portions of the property which were not occupied by the residence were graded by the defendant corporation. According to Mr. Bobrick, the contract of April 30th provided for a "fenced in" back yard. This fence was not constructed until the last few days of 1965.
