Case Study: Curved Wall of Windows in Home of Architect Jim Belli






Architect Jim Belli has helped create unique and award-winning buildings of all kinds, so when it came to designing his own home, he certainly didn’t want to be limited by standard-sized windows.

“There was no question about the windows I would use,” Belli said. “Not many companies could build a product to fit this home, and I knew Marvin would really stand behind their windows.”

A curved wall of windows on the first floor creates the feel of an open porch, with white extruded aluminum exterior cladding for minimal maintenance. Marvin created 12-foot-tall windows for the second floor bedroom that were made with a single sheet of glass. Interiors had to be solid wood that could be treated with a light pickle wash.

“Many companies finger-joint the wood in their windows, so you have to paint them,” Belli said. “Marvin’s interior is clear wood, so you can really show off the grain.”

The home was designed by Belli and his firm Belli & Belli Architects & Engineers Inc. in Wheeling, Ill. The home was built by contractor Valentin Markov of Markov Construction Co. of Wadsworth, Ill. Be sure to click on the small images you see here to see larger versions.
