The first year Bob Webb Homes used transom windows in the showcase house the company built for a home tour, visitors described the property 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 said. ‘‘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, said 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.
The see-through doors to the exercise room serve two functions, he said. They help incorporate the workout area into the main room and provide natural light to the whole space. The doors work because the architect also incorporated deep, wide window wells into the basement’s design. ‘‘It’s amazing what those deeper wells can do. It makes a huge difference, and that light bleeds into the rest of the lower level,’’ Shively said.
In several homes that Narofsky has designed, he has found an extreme solution for incorporating natural light in the lower level: digging out the layers of soil around the basement. In the space that’s created, homeowners have planted terraced gardens and, in one case, added a pool.
Homeowners who aren’t planning to build a new house still have options — at a variety of price points — for bringing more natural light into their space, said Jim Bimstefer, an associate broker with Keller Williams Realty in Baltimore.
‘‘When I’m going to sell a house, one of the first things I address is, ‘How can we get more light coming in?’ ’’ Bimstefer said. ‘‘More light makes a house feel bigger.’’
The solution can be as simple as trimming bushes and trees that are blocking windows, removing screens, or keeping blinds raised during showings, he said. ‘‘There a lot of little things that can increase the value of the home,’’ he said. ‘‘If there is vegetation in front of the windows, absolutely cut it back. Clean the windows. Let the natural light in.’’
Other options can be more pricey, like adding glass doors, enlarging windows, or installing skylights. Those improvements are best done long before listing a property so that the homeowner can enjoy the benefits, he said. The budget considerations are ‘‘completely different’’ if you intend to live in the house for many years before selling it, Bimstefer said. ‘‘Go crazy. Pull the walls down. Replace the old front door. Open it up. Put as much glass in as you can.’’
As a remodeler, Christopher Wittmann of Callen Construction in Muskego, Wis., regularly considers utilizing natural light when helping homeowners plan renovations. Depending on the project, he might suggest larger windows, glass doors, or removing a wall, Wittmann said.
He doesn’t hesitate to suggest more glass these days. ‘‘The energy efficiency has increased in windows and doors,’’ he said. ‘‘You can create a lot larger footprint in glass.’’
