The Invention That Accidentally Made McMansions
This is a really interesting video about something called the gang-nail plate, a construction innovation that enabled larger roofs to be built on houses, removed the need for internal load-bearing walls, and made the process of construction cheaper & more efficient.
While it helped streamline building processes and cut costs, it also encouraged rapid housing expansion and larger, more resource-intensive homes. The result was an architectural shift that contributed to suburban sprawl, increased energy demands, and homes increasingly treated as commodities rather than unique, handcrafted spaces. These changes reverberated through building codes, real estate markets, and even family life, influencing how we interact with our homes and one another.
The story of gang-nail plate illustrates an inescapable reality of capitalist economics: companies tend not to pass cost savings from efficiency gains onto consumers…they just sell people more of it. And people mostly go along with it because who doesn’t want a bigger house for the same price as a smaller one 10 years ago or a 75” TV for far less than a 36” TV would have cost 8 years ago or a 1/4-lb burger for the same price as a regular burger a decade ago?

This is the name that'll be displayed next to comments you make on kottke.org; your email will not be displayed publicly. I'd encourage you to use your real name (or at least your first name and last initial) but you can also pick something that you go by when you participate in communities online. Choose something durable and reasonably unique (not "Me" or "anon"). Please don't change this often. No impersonation..
Note: I'm letting folks change their display names because the membership service that kottke.org uses collects full names and I thought some people might not want their names displayed publicly here. If it gets abused, I might disable this feature.
If you feel like this comment goes against the grain of the community guidelines or is otherwise inappropriate, please let me know and I will take a look at it.
