It’s instinctual, really: During the winter, people naturally prefer to hunker down indoors, protected from the frigid temperatures and severe storms that are signatures of the season. When spring finally arrives, however, everything changes, and we head back outdoors to enjoy the fair weather as much as possible. In short, we typically think and behave as if indoor and outdoor spaces must be markedly distinct and separate. But it doesn’t have to be that way—at least not any more. Homeowners today can choose from many styles of windows and doors designed to erase the line between the interior of the home and the great outdoors. Some of these windows are familiar, timeless favorites, while others are brand-new, made possible only by the latest advances in design and manufacturing. All offer compelling advantages for those who crave more natural light, a heightened sense of space, and a feeling of oneness with nature no matter the time of year.
