The GreenHouse patrons include Mary Robinson (former President of Ireland and global environmental campaigner) and Al Gore (former US Vice President and global environmental campaigner). The GreenHouse is also supported by the London Development Agency (LDA) and the London Climate Change Agency (LCCA).

Several partners are already involved in making The GreenHouse a reality, including: Buro Four (Project management); Bates, Wells and Braithwaite (Lawyers); and King Sturge and Colliers CRE (Property advisers). A competition will be launched to find an architectural firm for The GreenHouse.
