Density has many advantages: shorter water and sewer lines per unit, less sidewalk and road maintenance per unit, better public transit with more potential riders.
A complex can be heated and cooled with an environmentally friendly geo-thermal plant that quickly pays for itself with almost zero operating cost. Higher density doesn’t have to be an ugly rectangle flush with the sidewalk.
Moshe Safdie designed an admirable high density community with terraced units for Expo ‘67 in Montreal.
Perhaps the plans can still be dug out of the archives.
We need density but density with imagination and concern for the environment.
