Put a different way:
- Higher density reduces land costs per unit
- But higher density can also increase construction costs per square foot
The 2nd effect often more than offsets the 1st; land costs are not huge for high density buildings

Hey DC, I heard you wanted policies to encourage new "family sized" (i.e., 3-bedroom) housing units. Arlington has a new policy where 57% of the resulting units are 3+BR; it's called ENDING SFZ.

Gentle reminder that ALL of the growth in single-person households since 2000 has been among seniors. Singles age 15-64 were 16.6% of US households in 2000, and 16.5% in 2020.

Going back to @ebwhamilton.bsky.social's point: large units are a distribution problem! More small units for seniors would free up more houses for families.

Pertinent to single-stair: new apartments (with sprinklers, compartmentation, and two stairs) are MUCH safer than older apartments with just two stairs, or houses. The safety difference isn't the stairs.

Here's actual Data Center Alley in Ashburn VA, surrounding ex-AOL HQ.
The two hotels smack dab in the middle have 1,600+ TripAdvisor reviews between them, and *zero* mention data center noise. (Many reviews mention noise from IAD flights.)
The houses at upper left are ~$1.2M.

High-rises in the US became unusually costly since the 1980s, far outpacing the already high inflation for low-rise buildings and outside the US.
Just saw this graph (1965 report for NC govt) showing almost no cost premium for high-rise, which is just bonkers. No wonder so many got built!
