Builders using more glass in home design as quality improves

The first year that Bob Webb Homes used transom windows in the showcase house the company built for a home tour, visitors described the house as bright, warm and inviting. While few mentioned the windows, company representatives said tour participants were responding favorably to the additional natural light provided by the horizontal windows above the home’s more traditionally placed windows.

“They couldn’t quite figure out why our house felt different,” said chief operating officer Scott Shively. “It was all the natural light. It just makes you feel good.”

Taking a lead from architects who design office buildings, residential builders and architects say they are increasingly looking for ways to incorporate natural light into homes. (Numerous studies have shown that office workers with windows are healthier and happier.)

In addition to transom windows, many new homes include large sliding glass doors, interior glass doors and thoughtful window placement that lets light pass through multiple spaces.

Improvements in weatherproofing and insulation materials and in installation methods for windows and doors have made it possible to increase the amount of glass in a house without creating drafts, said Shively.

“We’ve figured out a better way to layer houses,” he says. “We can seal the entire house up around the windows.”

In many cases, architects are incorporating these features because they see their value — even if clients don’t request them, says Stu Narofsky of Narofsky Architecture in New York City. Sometimes the additions are simple, like placing a bedroom window where the light it lets in will illuminate a hallway, or adding glass panes to a door for the same purpose. Other additions are more dramatic, like making an entire wall of glass.

Bob Webb’s latest show home, designed for the 2018 BIA Parade of Homes in Columbus, Ohio, features a retractable glass wall in the living room and a basement workout room that’s delineated by sliding glass, barn-style doors. More Midwest builders have begun using the retractable walls, which have long been prominent on the West Coast and Hawaii, because they too have undergone improvements that allow them to be used in colder climates, Shively said.
