When a bicoastal couple decided to build a new home along the Lieutenant River in the historic town of Old Lyme, Connecticut, they wanted privacy and plenty of space. They also wanted to capitalize on the unique quality of the area's natural light—an effect so magical that a century ago, it attracted numerous American Impressionist painters, who promptly dubbed it "Lyme light." Courtesy of MarvinIn this, the owners succeeded mightily: Among them, the project's three buildings—main house, carriage house, and pool house—feature no fewer than 110 windows and doors. And for each one, the build team turned to the Marvin Ultimate collection. The handcrafted, customizable windows and glass-paned doors, frequently arrayed to create "walls of glass," allow for an assortment of divided-light designs that deliver on three fronts at once: creating intriguing patterns and subtle gradations of light in every room, giving life and sparkle to the exterior, and, of course, ​​artfully framing the landscape beyond. "It's right on a tributary that leads to the Connecticut River—you've got marsh, cattails, osprey nests," says builder Nick Sapia of Connecticut-based Sapia Builders. "You want to do anything you can to capture that view."Ultimate windows from Marvin are available in a wide range of styles, sizes, and shapes—including specialty options such as triangles, octagons, and the arch-top windows shown in the living room above—and can also be customized to fit a specific placement challenge or design idea. On this home's front facade, for instance, a round window high on the gable was custom-designed with an intricate combination of curved and straight muntins dividing the panes of glass. "It was a tribute to one in the original house on the site," says Sapia, who worked with architect Scot Samuelson and interior designer Janine Dowling to bring the project to life. "If you can dream it and draw it, Marvin can build it."Courtesy of MarvinThis wealth of options allows for visual variety—the home features casement, picture, and specialty windows—while maintaining a cohesive overall look. The resolutely traditional exterior is enlivened by swaths of SDL (simulated divided lite) windows, which deliver the classic gridded look of multiple individual panes without sacrificing the energy efficiency of single panes. Combining those with Ultimate Swinging doors, as in the pool house below, creates sweeping glass "walls" that offer the greatest possible amount of light and access to views.Courtesy of MarvinThe Ultimate collection represents the brand's most extensive selection of features, options, colors, and finishes. Each piece of wood is individually sanded, conditioned, stained, and oven-cured (ensuring structural integrity) for a stately, high-end look both inside and out. "You want a sense of permanency," Sapia says. "Something of that quality and craftsmanship tends to have longevity."The windows invite that spellbinding Lyme light indoors, of course, but it's the vistas outside that steal the show. "From any point on the first floor, because of the glass, you're brought into the site—literally," Sapia says. "When you have such a dynamic view, with a bend in the river, the beautiful work inside the house almost goes away. You walk in and go right to the windows to gaze out."To learn more about Marvin Ultimate windows and doors, click here.
