Kernrechtsfrage
Whether the lease of bare land became a commercial lease subject to the formal notice and tenant-protection rules for business premises.
Extrahierter Entscheid
No. The leased object remained bare land; the containers and their rooms were movable constructions not forming part of the leased premises, so the rules for commercial premises did not apply.
Extrahierte Begründung
A ground lease does not ordinarily become a lease of premises merely because the tenant may install movable constructions. The parties had not agreed that the landlord would acquire the containers or that they would alter the contractual object.
