it's not that density per se drives down existing costs, but density almost always brings more housing stock to the market (unless they are simultanously tearing down housing elsewhere) and housing stock drives down the cost of housing, which is the point of the original article.

So if we take it as an assumption that density increases housing stock, there is lots of evidence that density drives down prices of existing land/home values.

It seems like it would drive down housing prices, but (given limited zoning) drive up land prices?

[buzzy_hacker]

Yes, that's correct. See https://news.ycombinator.com/item?id=47437907

Density is not going to drive down cost for the same kind of housing. A SFH is not the same as a smaller home on a denser plot, much less an apartment block in a high rise. So the SFH owner who pursues increased density does indeed benefit.

Even from a quality of life perspective, imagine having an SFH in city center that is within walking distance to shops, job, activities etc.
