The reason I prefer low rise (especially in the 3-6 floors range) is because they require less specialized service. Maintaining the systems for a 40 story building requires specialists in hvac, elevators, plumbing, fire suppression, window washing, painting, siding, etc. that are simply less available than the folks who know how to get up on a ladder and just fix it. Low rise also decentralizes services needed to support social housing, and allows local communities to build relationships that are less adversarial with the housing. (Which, imo, might be a uniquely American view that social housing is for the poor only.) So, in the initial rollouts, I think it makes it appear more palatable to American communities. Now, I agree, high rise is more efficient across other axes. And I'd take well maintained high rise social housing over the current status quo. I have preferences here, but I don't believe that high rises are wrong. Just not my preference.
