Or you know, Japan. They are such slackers that they have a special word for death by overwork (karoshi). I hear they live in giant mansions.

My point is simply that if everyone works less, society will have proportionally less material stuff.
Given all that, "houses would be proportionally fewer, smaller, and and in need for repair...unless we assume builders and maintenance people are exempt from working less" is not actually self-evident, and is more likely to be taken as an attempt to paint an exaggerated picture for rhetorical purposes.
There are lots of things that can be done, but they revolve around increasing either productivity or increasing efficiency. Neither of these is synonymous with simply cutting back on work.
This partially contradicts your point.
What I would add (to reconcile the two points), is that one kind of work is not fungible with another kind of work. Yes, people work very hard in Silicon Valley -- but they are not working hard at building houses. If they were, there'd be a lot of supply, and the price would fall.
Overall, this is perhaps a comment about the (mis-)allocation of work in society.
Time and effort and suffering are distinct from value creation.
A large portion of workers believe their own job is "bullshit" and does nothing to benefit society. Perhaps if we had more breathing room we could find ways to move workers into meaningful jobs.
It's complicated, and working fewer hours doesn't necessarily mean less productivity.
