sure, but the things we're talking about are 10m^2, or a little more than 300sqft.
If you are building for me, you have a water closet with toilet and shower, and then a sink, but no real kitchen. I eat out or at work anyhow; a desktop convection oven is overkill for my kitchen needs.
I mean, I think at this point we're around/above the size of the bedroom most people rent around here? I mean, at that size, I want a murphy bed, but even without, this is a size a lot of people live with right now.
Sure, I'd prefer some place bigger... but if you sell me 10m^2 in the bay area, say, for a quarter million dollars? I'd vastly prefer that to the really big place that a quarter million gets me in the midwest.
Preferences vary.
