An artist and designer known for her exuberant multimedia creations, Katie Stout used fringe, mesh, and vinyl to create her Trojan Sconce.

Talo Mini chrome sconces from Artemide installed atop the mirror in the master bathroom effectively disappear, becoming what Maca calls “subtle 3-D sculptures.” The Neo Blanco vanity, from Porcelanosa, is clad in the same Douglas fir as the ceiling. The IQ faucets are from Jado.

Don’t be afraid to invest in organization systems for your office, closet, and bedroom. They can make all the difference!

Vila D’Acosta-Calheiros hung a space-saving wall shelf in the library. The table is by Eero Saarinen; the Tolomeo lamp is by Michele de Lucchi for Artemide. The red beanbag-like Sacco chair is by Zanotta, as is the Sciangai coatrack in the hall, beyond.

A Noé Duchaufour-Lawrance chair, Charlotte Perriand wall sconce, and Greta Grossman Grasshopper floor lamp round out a corner in the living room. Deau made the side table herself.

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.

Anglepoise’s Original 1227 was launched in 1934, and is considered the archetypal lamp from the British company. The lamp took off where other contemporary task lamps left off, using a newly developed constant spring technology to create a lamp that was extremely flexible and adjustable, while also maintaining a consistent balance and stability.

Pulpites Lamps Made from shredded and recycled cardboard but fashioned like a piece of wet clay, the Pulpites lamp serves as an object lesson in paper’s potential to not only record ideas, but also to become the raw material of good design. Photos courtesy of Dear Human.

"When you buy something from us, I want you to keep it forever, because that's how long it's going to last."

The brainchild of Cincinnati-born and Brooklyn-based designer Paul Loebach, Areaware's Shanty Lamp ($75) is crafted from pine and references "Shinto temples and humble wooden cabins." We think it's more the latter than the former, and love that it has a scrappy sensibility and affordable price tag. More a showpiece than a streaming light source, the table lamp illuminates with a five-watt bulb.

Pulpites Lamps The Dear Human studio shares a building with a garment factory, so when the duo began playing with paper, there were plenty of cardboard dress forms and packaging material to use. Pulping, molding and shaping the geometric molds resembled creating with clay; they even dry the finished product in a computer-controlled industrial kiln. Photo courtesy of Dear Human.

At a renovated farmhouse in the Italian countryside, a crisp, modern white plaster fireplace and hearth infuse the interior with coziness and warmth. The firewood is stacked in a nearly-frameless niche next to the fireplace that is lined with metal, adding a bit of shine that contrasts with the rustic firewood and wood ceiling and beams above.

Created by American industrial design firm Cerno, the Acuo LED Wall Sconce is comprised of a three-sided wood box that has been deconstructed to create a more abstract silhouette.
