Rem Koolhaas on OMA's current preoccupations

In the second instalment of our video interview with Rem Koolhaas, the OMA co-founder discusses two of his current preoccupations: the countryside, which he is addressing for the first time; and generic architecture, which could result in neutral, copyright-free building forms.

Both topics are discussed in the OMA/Progress exhibition which opened at Barbican Art Gallery in London last week.
