For what it's worth, I recently bought a new-build condo-ownership model townhouse in Silicon Valley that is effectively a row house. Six units in a building, three stories each. It's not quite the same, but it seems to be cut from the same mold.
How is the shared wall? I used to live in an old brownstone sorta place and that thing was like a tomb in terms of noise.
Now I live in new construction which is timber framed, cheap drywall, and cheaper california insulation, and I can tell what specific video game my neighbor is playing along with his bowel schedule. Once this lease is up I'm running for the oldest heaviest looking building I can find.
Prices are well over $1million. These developments are quite common around the south bay. There are two more similar developments within a couple of blocks of this one, and I used to live in yet another over in Milpitas.
Very cool, thanks for sharing! Seems like a decent quality of living, definitely higher density than I was imagining, but it could foster community and lead to more efficiency than all single family homes.
