GRI Global Club

GRI Global Club

The GRI Club is a global fraternity of real estate leaders. Members find the club a useful way to maintain valuable relationships, find new business partners, and strengthen their global networks.

Guided by local and regional advisory boards, ‘Club Meetings’ focus on a theme, sub-sector or micro-market. On a larger scale, ‘Open Events’ bring non-members and members together for high level debates with global participants.


Membership is subject to approval by a committee of peers and is reserved exclusively for senior investors, lenders and developers*.

Qualified individuals (C / Director Level) that believe they could benefit from being part of such a global community are welcome to further details.

*Some leniency is given to those outside this category up to a maximum of 10% ratio of the Club.
