Adam Tarr - United Kingdom
Adam Tarr, Founder and Principal of Mzo Tarr Architects, London UK has developed a reputation for designing buildings based upon the principles of Game Theory. Adam studied at the Architectural Association, London, where he received the Eileen Gray Scholarship Award & Alexander Memorial Award. Adam is an award-winning RIBA Architect (Royal Institute of British Architects) and continues to practice, teach, lecture and write internationally on the potential of Game Theory within architecture.
We were approached to design a GAME THEORY concept for a 13 storey residential tower on the site of an existing Indian restaurant, near Canary Wharf, London for the private rented sector, to assist with the site’s investment. (And as of September 2015, due to our work, 4 parties are competing to invest & develop the scheme).
Again collaborating with Dr Andy Lewis-Pye, we used the famous NASH EQULIBIRUM (named after the late Nobel Laureate, John Forbes Nash, also of ‘A Beautiful Mind’ fame) to create a non-zero sum game which enables a win-win scenario for both the developer and tenants.
For Londoners, the priorities when choosing a property are location and space. In this context, space refers first to the size and quality of internal space, and secondly, whether there is private garden space. In the course of our research, we also identified that a tenant is more likely to renew their lease if they have a good relationship with at least one neighbour. With this information about tenant priorities and behaviour in mind, we created a game that encouraged the flat occupants to create garden space.
Each floor consists of 5 private flats (shown in green). The shared communal space (highlighted yellow) in the centre will encourage community spirit as well as offering a certain level of garden privacy. However, flat occupants have to trade part of their private floor space to create it. The amount they trade is up to them; they can trade as much or as little as they choose but to encourage the tenants, the rules of our game state 2m2 of communal garden would be created for every 1m2 of private space given up. The amount of garden space created, depends upon the decisions made by the flat tenants. Some tenants of course chose to be selfish, giving up no space in the hope they could use the garden created by the other four flat occupants more selfless decisions. But the largest spaces in terms of private and communal garden space were created on those floors where tenants were unselfish. Greater collaboration led to better results. Our tower game enables a win-win scenario for both developer and tenants.
A simple concertina glazing system makes the external envelope flexible in response to the tenant’s desires/priorities, because the game takes into account that we are all different. This approach brings the structure to life and provides a physical representation of the interactions occurring inside the building between the flat tenants.
The exterior glass changes as different tenants arrive and a new Nash Equilibrium is reached.
The game enables a win-win scenario [non-zero sum game]:-
1. The short-term tenants can revert to the original size of floor space at any time;
2. It enables the tenants to trade private space for a larger shared internal garden for their floor;
3. The landlord benefits, as good neighbourly relationships have been proved to increase lease renewals by 90-95%.
