What I notice (since we're talking about 'Projects' it seems relevant) is that there is a very low take up of the Tiny House concept among the black population which mostly inhabits social housing schemes similar to the Projects. The next smallest group is working class whites but this group is still influential in the movement.
This is curious because a self built Tiny House is very affordable. You can build one of these for less than 10k: https://www.tinyhomebuilders.com/images/products/simple-livi...
This is important because any social housing policy designed to decrease poverty requires a large amount of 'buy-in' or goodwill by the residents or it shall fail.
There is of course the question of land for THs, but that thorny issue has already been overcome by most Tiny House people in a variety of ways I won't list here, although I admit it is a serious concern.
I went in search of a black person who lived in a Tiny House. She had immediately understood the nature of the question and said a bunch of things on the subject, what stood out is that you might be able to sell the idea of being frugal, minimalist, eco-friendly, outright home ownership i.e. autonomy, practicality and economy to the majority white population that makes up the Tiny House movement e.g. poor students and downsizing retirees, but selling the same ideas to the black population is a very difficult sell.

She said while many of the whites are coming from the suburbs i.e. been there, done that, the American Dream for blacks remains to have a big house with its associated trappings. That is when they know they have 'made it'. It follows that a re-imagining of the American Dream is necessary for the black population, just as has been happening for the people in the Tiny House movement, but different.
Where I don't concur with Miss Pearson, is that I think this is regression. For individuals it is a good adaption, yes, but the net affect on a society is indeed regression. Big Questions need to be asked about why that's happening.
