What RO say

"CUBE provides a unique opportunity for us to collaborate with our tenants as we continue our journey to a more sustainable future. As a landlord, engagement with our tenants is paramount, and improving energy efficiency across our buildings is a key priority for us. CUBE is a first for the real estate sector and the competition comes at an important time"
