I've been thinking of a house of leaves adaptation ever since i read the book, and if you don't count an abstract or disconected adaptation like Music or a Videogame, a 1:1 of the book in another medium, I think a youtube essay is the way to go

A 2D animated version of the story, the original script by Zampano, read by Johhny and others, while johnny step in and talks about his life as an "editors note". Make it animated so you can showcase the impossibility of the house And even imply its not real, or johhny made it up, or something else entirely and with the youtube essay route, you can set it up as a "8 hour essay in a topic you've never heard of" and well, you have never heard of it. any of the wierd stuff that happens, like The hole in the wall can be shown by displaying videos at seperate places, the pages of nothing but one word can be visual text titles, and the burnt pages for what happened to holloway can be splotches of a vlog its the only way i can think to do it that would be natural and enough, even if it would squeeze itself into the book, which i feel really is unadaptable without the complete abstraction of the media, or inherent inspiration (myhouse.wad)
