1969JL341 Pendant light by Juha Leiviskä for Artek.

On the second-floor landing, an Alvar Aalto A110 pendant light from Artek hangs above an improvised green space.

Arbel’s projects—both products and architectural commissions—follow a chronological numbering system. The house itself is his 23rd design, while the one-of-a-kind glass pendants that accent nearly every room like a starscape are called “28.”

Brammy and Kyprianou hung Koura pendant lights by New Zealand designer David Trubridge above the dining area. Their organic forms and diamond-shaped shadows create intimacy in the vast space. Among Bilardo’s contributions were the black tulipwood cabinetry and ceiling and the cantilevered concrete countertop that appears to go through the glass wall.

For the dining room, Freeman and Feldmann swapped their tiny table for developer John Walker's larger one since he was moving into a smaller space. They topped it with a $12 pendant lamp from Ikea and finished the "room" with a counsel from West Elm.

A built-in bench by the window is a cozy perch for Tyler. The herringbone flooring looks like wood but is actually man-made.

Nicolas Gervais designed the pendant lights above the kitchen island, which was designed by Plasse and built by woodworker Stéphane Bilodeau.

The black steel A110 pendants by Alvar Aalto match the Poliform ventilation hood and ebonized white oak cabinets by Leicht Haus. LED lighting is integrated into the island shelving. The drawers underneath are handleless and open electronically by touch using a servo drive.

"The kitchen refers to London’s feeling the most," says Stepanova. Pendant lamps from Normann Copenhagen illuminate the kitchen, all of which was fabricated by the woodworking studio Dyzyk according to Stepanova's designs.

In the Denmark home of designer Eglantine Charrier, original 1920s windows and moldings meet modern accessories like a black Caravaggio pendant lamp by Cecilie Manz for Lightyears.

As Østergaard says, “With a small house, you really consider everything you own. You don’t have 20 pots and pans, you have only four good ones.”

The architects used blackbutt wood for the flooring and Whisper White paint by Dulux throughout the interior. An A110 Hand Grenade Pendant Lamp, by Alvar Aalto for Artek, hangs above the white Carrara marble-topped island.

Happy Accent Now that the interior’s palette is firmly in place, Winterhalder has slowly been adding splashes of color. E27 pendant lamps from Muuto in the kitchen and guest room have red cords; one wall in the guest room is also red, with matching red locker storage. The inside of the front door is painted bright green. “For me, they’re kids’ colors,” she says. “I just love them.” muuto.com

The almost-entirely tallowwood kitchen is custom. Muuto pendant lights, bar stools by Alvar Aalto for Artek, a Vola faucet, and a ceiling fan by Beacon Lighting finish the room.

The Globo di Luce pendants in the kitchen are by Roberto Menghi for Fontana Arte.

Norm 12 comes in two finishes, pure white and simple matt white, the extra large light is intended for hallways or larger rooms, while the small light is meant to be hung over a table or in a nook.

Utilizing lightweight LED technology, Arik Levy's Wireflow pendant lamps are an airy, geometric take on lighting design.

"I always have ideas floating around, inspired by a number of deferent things: previous generations, art, technology, color," says Dowie. "I think a lot and process these ideas through thought—it is the ideas that keep coming back that we end up developing." In the case of the Line collection, the balance and lightness of Alexander Calder's mobiles was pared with practicality. "It's perhaps a more romantic approach, but I do hope to strike a balance between form and function."

Designed by iconic Scandinavian modernist Alvar Aalto, the Artek A331 Beehive Pendant Light ($1,020) comes in either brass- or chrome-plated steel. Aalto created this piece for the University of Jyväskylä in Finland in 1953 and ever since it's remained popular across the world. Standing alone or with other Beehive Pendants, turned on or off, it's a true work of art.

The 1968 house’s shape—a rounded triangle topped with a sweeping concrete roofline that suggests a helmet as it rises above huge banks of windows—lends itself totally to Kukkapuro’s philosophy. “It is a structure in waiting, prone to change as the landscape around it—not yet a form, rather a possibility,” he says. “It changes in harmony with the seasons and the moods of its inhabitants.”

Neyer is also working on prototype for a pendant lamp inspired by a yo-yo.

The couple designed the master bedroom, choosing a new red carpet inspired by the original and a Half Moon pendant by Allied Maker.

Lange’s predilection for vintage design punctuates the space. The office level includes a cozy guest room with a mid-century Heywood Wakefield-esque dresser serving as a bedside table.

This lacquered aluminum pendant lamp is basically a cube with three sides removed. There's a stretch fabric inside that spans the outer edges of the lamp and obscures the bulb.

The ALUE pendant lamp, also by Matti Syrjälä, is a multi-faceted piece with 12 edges of wood fiberboard.

German Artist’s Mike Meiré’s version of the Artek Stool 60 gives the iconic stool some pop. $390

Alvar Aalto’s Stool 60 In lieu of a coffee table, three of these stackable stools were grouped together. $308

In the living room, a vintage table and chairs by Edward Wormley sit in front of a Florence Knoll wall unit with a vintage jewelry chest by George Nelson for Herman Miller. The Hinaki pendant light over the stairs is by David Trubridge.

Aalto would often linger for discussion-filled afternoons in the Atelier's canteen. The A111 fixture (a variation of the A110 with brass tubing) was developed for Artek. In the company's prosaic naming methods "A" recognized that the design was by Alvar Aalto (his wife Aino's design were tagged AMA).

An assortment of dining chairs, including vintage iterations on the Eames shell chair by Charles and Ray Eames and Stokke's Tripp Trapp chair, are clustered around a table lit by a pendant lamp by Coco Flip Design Studio.

In the 2EM lounge, light fare like duck confit cassoulet and flatbread with lamb, blue cheese, and caramelized pears is served. Beacon-based vendor Niche Modern crafted the chandelier above the bar, and the stools come from Rexhill. A major philosophy of the Roundhouse is “keep it local.” Photo by Eric Laignel.
