I grew up in a city of mostly rowhomes and I love them. Plan on buying one one day.
You still get walk-ability, sense of community and good population density (not as good as a high-rise but still good), but also more privacy, and the space is more conducive to raising a family than an apartment. Also they’re cute as fuck and people can paint them different colors and have cool little gardens on their porches and stuff.
You are very right. While it looks nice in terms of energy usage it is horrible. Design is also controversial and not ideal imho. Looks fun though.
