Concrete doesn't set in the cold. Also various construction glues and sealants often don't set right either.
That's literally it. You frame a house after you pour the foundation, so it can technically be done when it's cold, but you start the framing asap so it's not gonna be cold when you just finished the foundation.
The concrete thing is mostly that residential concrete companies don't want to do what it takes to produce a good product. They want to frame pour and strip in like 6 hours so they can get like 2-3 units a day done. To do that you gotta use a ton of accelerant. Makes for shitty concrete and you can't do it in the winter because the frames have to be insulated so the curing concrete retains it's heat. Most commercial jobs work just fine in the winter, they just insulate and use blankets or warm water flood curing.

Everything else follows from there.
