I own a "contemporary" home, ca 1979. Avant garde designs tend not to age well from a resale perspective. Glass walls are impossible for curtains. And if the home has skylights (I have an unlucky 13 skylights), be aware that these are basically holes in your roof. Custom windows and doors age like anything you could buy from Home Depot, but parts are impossible and replacement is five times more expensive. After 30 years of "innovative" heating and cooling solutions, I'd be happy with a working window air conditioner and a Weil Maclain oil boiler. Not to be discouraging, but this has been my experience, yours may differ.
