A Shell lease agreement, common in commercial real estate, is a lease for an unfinished interior that the tenant will adapt to their specific requirements. The term derives from the fact that the rented object is an unfinished “hull” of a building, often a unit in a new shopping mall where the tenant must complete the construction and add all the necessary furniture, furniture and appliances. A structural work contract defines the construction and improvements for which the owner and tenant are responsible. Often, the landlord will offer the tenant a financial incentive for the completion of the work. The lease agreement set minimum requirements for the efficiency of the HLK. Today, some of the leased space my company has worked on since the first core and shell design submission had described HLK devices with better efficiency than in the lease agreement. .
