I install ductwork and furnaces/ac's for these monstrosities. They tear down a little bungalow house and put up this gigantic home. Who the the hell wants to heat these monstrosities and walk up all those stairs. You need a small fortune to furnish the damn home and lets not even talk about heating/electrical costs
I'm pretty sure most people hang out in the kitchen/living room..now you got all these vacant rooms..and most times these places are sterile unwelcome places.
Hey I don't mind doing full system installs for these monstrosities, I just don't see the appeal of them. Give me a bungalow any day.
