With its app, Sunn allows users to select any time and location, and the light will track the patterns of the sun accordingly. Trying to ignore the gray weather outside? Users can also select which season they'd like the light to reflect.

The concrete wall behind the porch provides a backdrop for the wood stove and privacy from the road.

A bathroom is tucked beside the new sunroom behind the sliding barn door, which was found at Albany Architectural Salvage.

The screened porch functions as the building’s primary bedroom, creating a cabin-like experience.

The light gradually increases or fades out at morning and night. The idea is that the light helps users adjust to a natural cycle of sleeping and waking. The app also analyzes and adjusts to users' sleep schedules over time, so it can coordinate wake-up with the lightest phase of sleep. It leaves on a faint, moonlight-like glow at night, so people can get around.

The LED light is available in two sizes, and can be easily affixed to a wall. Find out more about the light and app here.

Helsinki architect Ville Hara and designer Linda Bergroth collaborated on a prefab shed-meets-sleeping cabin, which can be assembled with little else than a screwdriver. Bergroth, inspired by nomadic yurt dwellers, wanted an indoor/outdoor experience for her property in Finland.

The residence receives all-day sun, which is particularly captivating when bathing the rooftop area in a late afternoon golden glow.

Jocie designed the custom built-in bench. A vintage Moroccan wedding blanket is paired with a vintage rug from Graham’s grandparents and two pillows from Block Shop Textiles.

The new interior includes a meditation room with an Isamu Noguchi lamp, flooring made of tatami mats, and a Murphy bed for visitors.

The simple finishes provide a backdrop for the homeowners’ collection of carefully curated furnishings, many of which are vintage (and, yes, cozy). One partner is a graphic designer, and she brought her own strong design sensibilities to the project. “She likes contrast, black and white, and bold color,” says Cuppett.

For the time being, Cori does her painting in the dining room. “Eventually we’ll build a studio here,” she says. “But for now, because we eat outside most of the time, the dining room it is.”

The meditation studio features a view of the property through black-stained slats.

Inspired by a French farmhouse, this rustic she shed features multi-pane French doors, exposed roof rafters and joists, and earthy terra cotta floor tiles. With its wide-plank wood cladding sitting on gray stone foundations, this shed looks as though it has been around for centuries, but also has a simple, modern sensibility.

Out in rural Oregon, a she shed was constructed almost entirely of old multi-pane windows that the owner was able to reuse from local construction projects. Since cross-ventilation was a priority, more than two-thirds of the windows can be opened. The wide-plank wood floors help continue to bring the outdoors in, and minimal interior furniture and finishes keep this space comfortable for meditation.

A baby-blue George Mulhauser Plycraft lounge chair and plants make this a cozy nook for reading and relaxing.

The meditation room overlooks a nearby hilltop in one of the clients' favorite views, framed by floor-to-ceiling glass windows.

In the sunroom, Clara designed a custom bookcase to span the length of the space.

A custom-designed chairlift system from Versicor allows Matthew access to the tower. “The new house has really liberated Matthew. My goal is that he will have access to everything by one means or another,” says Ed Slattery.

The yoga studio can also be converted into guesthouse.

A tranquil nook allows the homeowner to practice yoga.

The sunroom—or “museum of natural history,” as the couple call it—showcases an array of objects, including a massive chair carved from a single tree trunk and a terra cotta elephant used as a side table.

One of the home’s more fanciful features is a meditation tower that offers views to Baltimore’s Loch Raven Reservoir and beyond.

Exposed timber rafters support the roof, which is peeled back at the rear of the site to draw in warmth from the northern sun.

The window sill is Virginia Mist Granite, which extends as a countertop on the exterior side. "One of the things we were really excited to be able to do was to create that Nana wall opening, to connect that interior space directly with the exterior terrace," says Garry. The difference in grades between the exterior and interior means someone can comfortable sit inside and converse with someone sitting outside at the bar.

The long hallway leading to the bedrooms gets spectacular afternoon sun, lighting up the family’s many works of art.

Shondi and Dash enjoy the new sun room space, which now provides the perfect spot for morning coffee, as well as a home for Shondi's plants. The sun room is "the connection to the outside," says Suzanne. "We changed the materials on the floor from wood to Chicago common brick, so it feels a little more exterior. It also has a heated floor underneath so it’s warm in the winter and also absorbs light during the day, which keeps the floor warm."

On nice days, doors can be opened for indoor/outdoor flow.

The light can also be set to sync in real-time with the quality of light and the weather outside. It also gives tips on how to use light and the app to minimize fatigue, and so on.
