Rodriguez, a designer and architect who runs the studio Agi Miagi, created the pendant lamp and terrariums in the dining area. The space is open to the living area, where Brown’s son, Hugo, sits on a Living Divani sofa. The countertop-table is by Bercy Chen Studio.

The Kelleys furnished the cottage with help from Suzanne’s daughter Betsy Burbank of Betsy Burbank Interiors. Classic modernist icons, such as a Saarinen Womb chair for Knoll, a Herman Miller Eames lounge chair, and an Eileen Grey E1027 side table look at home alongside present-day pieces such as an Encore sofa (which handily folds down into a sleeping surface) from Room & Board and a Doka rug designed and produced by Stephanie Odegard. The Wohlert pendant lights from Louis Poulsen were designed by Vilhelm Wohlert in 1959, but grouped as such, they appear distinctly contemporary.

Halfway through a pregnancy isn’t exactly the ideal time to buy a house. So after spending months scouting San Francisco’s Victorians and turnkey cookie-cutters—and almost defecting to the East Bay—Lorena Siminovich and Esteban Kerner decided to put the hunt on hold until after their baby was born. But then one afternoon Kerner, a design director with Old Navy, logged on to Craigslist on a whim. He saw a below-market listing for a single-family home in Noe Valley, their neighborhood of choice. With crumbly brick cladding, peeling rust-brown paint, and rotting garage doors, the house lacked curb appeal. But the Argentine couple was drawn to the interior. "It was amazing and strange at the same time," says Kerner of the 1,485-square-foot, multilevel, midcentury maze. "Mind-boggling," adds Siminovich. "It was just a knot of doors and a series of insane stairs to nowhere."

Builder Ross Percival helped finesse the finely tuned detailing that separates the internal slope from the rock outside (opposite). The Pedro wire stool is by Craig Bond for Candywhistle.

The concrete wall mimics the slope of the hill outside as a reference to early Maori structures that were dug into the land. The simple kitchen has strandboard cabinetry and an MDF island that conceals a fireplace at one end. The ceramic works on the built-in seat at right are by Raewyn Atkinson and Robyn Lewis.

Interior designer Anne Sophie Goneau gave an apartment in a former factory a bright makeover. The minimal gas fireplace is from Ortal, acting as a focal point in the room, complete with integrated shelving.

Modern Way.

A 606 Universal Shelving System by Dieter Rams for Vitsoe hangs tough on the only opaque wall of the living room. Russell-Clarke and Moolsintong designed the coffee table, and Marcel Wanders gets credit for the Bottoni sofa for Moooi.

On the outskirts of Austin, Texas, author Chris Brown and his dog Katsu head to the river; the path was once a dumping ground on top of a long-defunct underground oil pipeline. The green roof was conceptualized by John Hart Asher of the Ecosystem Design Group at the Lady Bird Johnson Wildflower Center in Austin.

Edgeland House, built on a cliff-top lot in Austin by architect Thomas Bercy for lawyer and writer Chris Brown, is topped by a living roof that helps it blend into the landscape. The concrete, steel, and glass house is divided into two distinct public and private halves.

Unable to alter the footprint of the building, the Deams created a backyard living area that nearly doubled the home's living space.

An architectural designer and an artist harnessed the collective power of their design firm to remake a dilapidated mid-century gem into a hillside perch for their family.

The living room is further lit by three protruding skylights angled to catch morning and afternoon light.

The home’s original living and dining rooms were updated with custom cabinetry and new fir floors. The living room sofa, coffee table, and lounge chair are from Blu Dot.

French doors in the living room let light into the kitchen and open onto a lovely garden.

Built-in bookshelves in the living room hold Sanders’s vinyl collection.

The second-floor bridge that leads to the front door flows from the outside in. “Tractor seat” stools designed by Bassam perch on a floor of pristine white terrazzo.

The nuri-en (an exterior overhang) is one of the few Japanese touches on the home's exterior. Paired with the continuation of the interior floor right out into the backyard, the home opens up to the outside quite nicely.

For a slightly funkier feel, opt for a variety of high-design chairs around your table. A less rigid approach to hanging art can also ease the hard lines of much modern decor and add to a more bohemian vibe to your home.

Its living room features an Eames LCW, Bertoia Barstools, and Eames Tandem Shell Seats.

Alex relaxes on the first-floor couch, with is filled with an array of pillows from Crate and Barrel, CB2, West Elm, Muji, and Blu Dot.

Architect Tamira Sawatzky used Ikea components—one-inch Lagan butcher block countertops and inexpensive Ekby Lerberg brackets—when designing the bookshelves along the living room wall in the home/studio he designed for himself and his wife in Toronto.

Orrill wanted the kitchen to be command central for entertaining, so everything is kept inside minimalist cabinetry—except for the copper pots and pans hanging on the back wall, painted in Pale Water by ICI Dulux Paint. The refrigerator is by Jenn-Air and the faucet is American Standard.

In Marquina and Font’s living room, a pair of kilim-covered chairs by Philippe Xerri, a chest of drawers by Piet Hein Eek, and a handmade Tunisian rug provide bursts of color amidst the overall scheme of white, ecru, and cream.

Behind the resin screen is the property’s centerpiece: an entry garden that Trainor recast as an outdoor living room. Sparta stacking chairs, a deep-wicker Baia sofa, and matching Baia armchairs, all by Mamagreen, are arranged around a custom concrete fire pit. Orange kangaroo paws lean in from the sides, creating a sense of privacy without sacrificing views. It’s a welcoming space that serves as a casual gathering spot when the weather cooperates.

The industrial stair leads to the upper level, where the bedrooms, bathrooms, and play space are located.

Surrounded on all sides by a sweeping Canadian hayfield, the 23.2 House is an angular ode to rural life.

The formal lounge plays host to Angelucci’s collection of mid-century modern furniture. A pair of Leather Sling chairs by Aussie-born sculptor Clement Meadmore sit under the window; a black Snoopy lamp by Achille Castiglioni for Flos is on the mantle.

Morten Bo Jensen, the chief designer at Vipp—whose headquarters are located in Islands Brygge—and his partner, graphic designer Kristina May Olsen, bought a loft space in the former Viking pencil factory in 2011. They bought the loft from its previous owner, one of five investors who purchased the circa-1910 factory building, roughly a decade ago, in a very raw state.

Edgeland House, built on a cliff-top lot in Austin by architect Thomas Bercy for lawyer and writer Chris Brown, is topped by a living roof to help it blend into the landscape. The concrete, steel, and glass house is divided into two distinct public and private halves.

Light floods the living and dining rooms, meaning Schneider rarely needs to turn on a lamp during the day.

The Mikado 2 sofa by Hans Hopfer for Roche Bobois is a bright and cheery centerpiece in the otherwise sedate living room. The nubby wool Photon rug from Design Within Reach warms up the expanse of concrete. The framed drawing is by the Los Angeles–based artist Daniel Brice. Huge sliding doors open the house to the outdoors and virtually double the Burtons' living space.

Walsh and Strongin's living room strikes a more rustic note.

Birdsall plays with her son Atticus in the living room next to a Charles sofa from B&B Italia. Formwork also designed the coffee table—fitting, since the architects come from strong fabrication backgrounds.

The sofa is a prototype that never went into production—the base slides out and the two cushions become flat for sleeping. Today, one can buy Risom furniture from a variety of sources, including Knoll, Design Within Reach, and Ralph Pucci.
