A Texas donut is an apartment building that wraps around an attached parking structure. I've seen a few different variations but the nicer ones have courtyards between the units and the parking garage that I imagine is more to allow cross breeze than anything else because being inside them would be incredibly claustrophobic. Still a huge waste of space but if you really want your residents to all have cars they kind of make sense because the parking footprint is more or less the same as you would get as if you built a low rise, plus you hide the cars from the street view, which is nice because parking garages are usually pretty ugly. You can also bury the cars instead and that works way better for somewhere like downtown Seattle, since real estate is just so mind bogglingly expensive in downtown areas of major cities, but honestly if you're living in the city it seems like storing the car offsite would make more sense if you really feel like you have to have one that badly because underground parking is also ridiculously expensive compared to above ground parking structures, plus you have to worry about water ingress and degraded pilings and all sorts of nasty shit. That actually happened in Florida and it took the building with it when it went. Then again that's Florida, it might work better when you're not building a high rise on a sponge.
