Lloyd Kahn has put together many a book on small, human-scale dwellings that break from the American McMansion White Picket Fence norm. Most of them are available electronically, except this one. This dead tree exclusive details all sorts of DIY'd motorhomes.
You won't find many Instagram "perfect" hospital white walls Sprinter vans in here.
You'll instead find homely things with stories. Like this "Birdhouse", which is quite close in many ways to what I have in mind to build. It's so cute!
@klardotsh I love Lloyd Kahn's work and writings. He now runs a nice newsletter on Substsack I believe, not sure about the platform (I can find out later if needed). He really is an inspiration.
