In a traditional Chicago neighborhood, Michael Yannell's new courtyard home has a distinctive butterfly-shaped roof that hides its 48 rooftop solar panels from street view.
His gorgeously green abode, designed to produce more energy than it uses, has other nifty design features. It's composed of two wings connected by a foyer and entered via a courtyard. One wing has a two-story living, dining and kitchen space and the other has a den, two bathrooms and three bedrooms.
