In a commercial lease dispute concerning a hospital building developed through a public-private partnership, the court determined the gross rentable area used to calculate annual basic rent.
The lease projected a gross rentable area of 135,000 square feet but failed to properly define that term, and the landlord's architect never issued the certificate contemplated by the lease.
Applying modern contractual interpretation principles and limiting surrounding-circumstances evidence to objective facts known at the time of contracting, the court held that the parties intended gross rentable area to correspond to the architect's gross floor area concept rather than the entire building area urged by the defendant.
The court fixed the gross rentable area at 142,907.5 square feet and left the parties to calculate rent payable from October 1, 2013 onward.
