Petermann: ‘One of the door manufacturers I spoke to concerning the Biennale is really worried about it. Fewer walls means fewer doors.’
Koolhaas: ‘Really?’
Petermann: ‘Yes.’
Koolhaas: ‘No!’
Petermann: ‘They are selling fewer doors.’
Koolhaas: ‘No, but… tell me.. in what way… how did he explain it? What was he worried about?’
Petermann: ‘Well, in homes the doors are disappearing because people want big living spaces, with kitchen, sitting and everything together, so there’s a decline in demand, but there’s also a decline in offices.’
