Ah, there’s your answer. I love rowhouses and think they and other “missing middle” are a great compromise for getting denser, more walkable, more transit-oriented communities while still avoiding being like Manhattan. True low-density sprawl (as seen in so much of the US and Canada) is detached single-family homes with large setback requirements, large parking minimums, and typically large lot size minimums. It’s purposefully designed to essentially enforce car-dependent sprawl.
The style of development you describe is what we call streetcar suburbs, as they were generally developed along streetcar lines in the days of yore.
