“But we mustn't be too general, we've got to support our points by referring to specific cases. So that'll need a lot of work. MIA: I'm afraid so”
B: the tutor insists on 'specific cases' rather than general statements, so any benefit for city residents must be evidenced before it is claimed.
“MIA: Good. We'd better decide now what type of housing we're going to focus on. How about housing for different generations living together? LEO: We could do. Or accommodation for one person? MIA: I think someone else is doing that. I was wondering about housing for the elderly? That's likely to become more important.”
A: Leo prefers Mia's intergenerational idea to housing for the elderly, since separating older people risks the isolation option A warns about.
“But I think the solution is to design multi-storey apartment blocks. MIA: Building up rather than out, yes”
B: the solution is 'multi-storey apartment blocks' — building up rather than out — which suits city residents short of land.
