Camatron Sewing Machine, Inc. (plaintiff) leased portions of a building from F.M. Ring Associates, Inc. (defendant). Camatron used the leased premises for manufacturing and also executive and administrative offices. The lease permitted Ring to change the layout or location of the public areas in the building. Ring wished to remodel the building’s lobby. The planned remodel would result in Camatron losing 46.5 square feet, which was approximately 25 percent of its administrative-office space. Camatron brought suit, claiming that Ring did not have the authority to take Camatron’s leased premises. Ring argued that the 46.5 square feet equaled less than 1 percent of Camatron’s total leased space in the building. The trial court granted Ring summary judgment. Camatron appealed.
