Dish’s Island sun lounger by Alexander Seifried for Richard Lampert, $2,430 Named for a character in Robert Altman’s film MASH, this weather-resistant lounge chair is sized to fit smaller urban spaces.

Jean-Christophe Aumas’ multihued Paris apartment houses both the highly sought artistic director and the stunning assemblage of furniture he’s brought back from his travels. Aumas designed the kitchen island, which is covered in marble tiles from Carrelages du Marais—the geometric floor tiles are from the same place—and strung the matrix of lights up above it. The barstools by Charlotte Perriand were discovered in a vintage store in Antwerp, Belgium. The green wall is covered in paint from Emery & Cie.

The inspiration for this prefabricated, modular family home on Fishers Island, New York, were the views that Tanney and Luntz saw from a 12-foot stepladder, which was balancing on the bed of a pickup truck when they first visited the site.

All about #red

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.

A corrugated metal roofing, pine walls stained a warm blonde hue, and an abundance of glass make this modern prefab feel much roomier than its 1,600-square-feet size.

The quiet, minimalist kitchen features a wall in the same “criptoméria" wood used for the bookshelf in the living room. A Davide Groppi Punto 2 PL light hangs over the dining table.

Landscape architects Reed Hilderbrand helped fill out the completed prefab by planting sedge grass on one of the house’s two green roofs to reflect the texture of the surrounding meadow.

This dwelling joins a number of structures—such as a boathouse and guesthouse—owned by one family and used for vacations. They needed a new house to accommodate new generations at the reatreat.

Warm wooden walls ensure the simple bedroom setup, a low mattress next to a Muuto Leaf table lamp, offers more comfort than the cold stone exterior.

The house is oriented to maximize views of the ocean and Edgartown to the west, and Nantucket and Cape Pogue Bay to the east. Natural sea grasses sourced from the surrounding area cover the roof of the building, providing thermal insulation while also dampening the noise of rain, improving air quality, and helping to manage rainwater flow.

The chromatic Paris apartment of Jean-Christophe Aumas holds a treasure trove of rare vintage furniture, displays from his work, and items curated from his travels. As the artistic director of the creative agency Voici-Voilà, he designs store windows and special events for clients like Louis Vuitton, John Galliano, Lacoste, Céline, and more; and so it’s no wonder that his own 1,023-square-foot apartment is teeming with character. The entire flat is self-designed in a fusion of his professional and personal flavors. Over herringbone wood floors, walls with painted shapes frame hanging artworks; colored cubes, created for a Sol LeWitt–themed Louis Vuitton display, pepper the space; and foraged furnishings ranging from flea market finds to designer pieces outfit the home.

Bernier’s firm designed the built-in storage, seating area, and kitchen island to be intentionally abstract, directing attention to the forest outside. Cabinetmaker Pixel & Scie manufactured the furniture.

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 walnut unit between the kitchen and dining room ties into the fumed oak floor,” Dubbeldam says. “The rest of the materials in the house—glass, marble, stone—were selected to offset the wood.”

According to Remijnse, since the only direction they could build on the small site was up, they decided to add height with a gabled roof.

The dwelling showcases the designer’s collection of Danish chairs and loungers from the 1940s, 50s, and 60s — including pieces designed by Kofod Larsen, J.L Moller, Harry Ostergaard, Bruno Mathsson, and Hans J. Wegner.

To further connect the indoor spaces with the New England landscape outside, glass walls in the living and dining areas slide open to eliminate the barriers between indoors and outdoors. Green slate tiles compose the flooring inside.

The smooth, raven-hued island in this kitchen is made of oak with a thin stone countertop. A Foscarini Gregg Pendant hangs overhead.

The firm collaborated with Kountry Kraft and its modular manufacturer, Simplex Homes, to expand the palette of materials, including the teak cabinetry used in the kitchen and dining areas. Interior designer David Bentheim suggested the marble backsplash for the bar area. Antique dining chairs, an LED Aurea pendant lamp by FontanaArte, and a Paolo Piva table from B&B Italia complete the room.

Dan Pacek, left, and John Roynon prepare cocktails at their 12-foot “display island” in the renovated kitchen of their home in New Jersey. The couple bought handles matching those on their Thermador refrigerator and used them on a set of pantry doors, one of which conceals the steps to the basement.

The homeowners were impressed by the way Salmela conflated the indoor/outdoor continuum. “We really needed that contact with the lake and the woods even when inside,” says Golob. All outdoor seating by Kartell.

The kitchen features a concrete island topped with marble. Deja-Vu stools by Naoto Fukasawa surround the island. A print by Guy Gormley, as well as a painting bought during holiday in St. Tropez, hang on the walls.

A second green roof is planted with sedum and plays host to one of the family’s favorite spots: a hammock. Bentheim suggested adding a trellis overhead to soften and balance the appearance of the facade.

Books pepper the Toronto apartment, but most are housed in two libraries, one of which is dedicated to art and photography. It also features a Palms lounger by Dutch designer Frans Schrofer and the painting Any Number of Preoccupations by Lynette Yiadom-Boakye. The second bedroom, which also functions as a library, has Vitsœ shelving and houses owner Kenneth Montague’s book collection.

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.
