A new proposed subdivision in one Chicago suburb will have “custom, high-end homes.” But the image provided suggests these homes will be right next to their neighbors. Do these things go together?

A description of “high-end” and “custom” plus looking at the rendering suggests these will be pricey homes. To have this square footage with a garage in a new single-family home build in an older suburb will cost buyers a good amount.
But the homes are so close to each other! Americans like single-family homes in the suburbs but they also like a little space. They like a lawn and an approximation of nature. They like some privacy and an ability to do what they want with their property.
The demand will be there for these homes, yards or not. Housing supply is limited. Some buyers want to pay for less yard space. The new spacious interior with features will outweigh other downsides. If plenty of Americans prefer private interior spaces, these homes will offer that. Like many in the suburbs, people can drive into their garage, close the door, and do their thing inside with little interaction with neighbors or the community.
I also imagine there are a good number of people in the United States who would look at the drawing above and not have any interest due to the lack of space around each house. These are denser suburban homes that do not appeal to everyone.
