For decades, homeowners hoping to increase their property’s value followed a familiar playbook summed up by the maxim: “more is more.” From supersize kitchens to sprawling guest wings, the assumption has long been that more square footage means more value. Yet architects and real estate agents increasingly say one of the smartest renovations doesn’t involve expansion but opening, specifically bringing more natural light into existing rooms. Long before open-floor plans became de rigueur, famed mid-20th-century architect Frank Lloyd Wright understood that a home’s sense of scale could be shaped as much by light, proportion and carefully framed views as by its actual dimensions. As he famously observed: “Light is the beautifier of the building.”
Today, advances in glass, structural engineering and building materials allow designers to apply those same principles in ways that often require surprisingly little additional square footage. The tools are straightforward: floor-to-ceiling windows, remote-controlled skylights, expansive glass walls and reconfigured floor plans. These methods allow daylight to travel deeper into a home while strengthening its connection to gardens, city skylines, mountains or the surrounding setting.
“In luxury residential design, the perception of spaciousness and the quality of experience is just as important, if not more, than the real square footage on paper,” said Mark Holmquist, an architect specializing in high-end residential design in Manhattan.
There is money in all that sunlight, too. Svetlana Choi, a real estate broker at New York City’s Coldwell Banker Warburg, saw how dramatically a single window could alter a home’s appeal. In a Central Park West apartment, the addition of a north-facing window helped transform a second bedroom into a primary suite with views of Central Park. A couple bought the apartment for $1.1 million, spent $300,000 on a broader renovation and sold it two years later for $1.565 million, according to Choi.

Homeowners are expected to spend hundreds of billions of dollars on remodeling and repairs this year, according to the Harvard Joint Center for Housing Studies, even as rising labor costs and expensive materials have made additions far costlier than they were just a few years ago. Remodeling magazine’s latest annual Cost vs. Value Report likewise shows that upscale additions recover only a portion of their construction costs at resale, prompting more owners to ask where renovation dollars can have the greatest impact.
Why Light Feels Like Luxury
Agents who regularly show luxury homes said buyers tend to respond to natural light long before they begin comparing square footage or finishes. Two homes may share similar floor plans, styles and asking prices, yet one immediately feels more inviting. Daylight is often part of the difference.
