"It only cost about $48,000 to build, which was incredibly cheap," says Turner of the Stealth Barn. "We got the Timber Frame Company to supply the shell, then we clad it and fitted out the interior and windows ourselves. The idea was to take the archetypal black tar-painted agricultural building and make an almost childlike icon of that."

The second-floor office is housed inside a rounded rectangle of concrete that the architect inserted on top of the old farmhouse.

“We really wanted to capture the ruinous quality of this old building rather than do something overtly new,” says Greg Blee, founding partner at Blee Halligan Architects. Before construction could begin, however, he and Halligan had to patch the remaining walls using stones found in the nearby river. Wherever a wall had collapsed, the designers inserted framing to create windows and doors. For the roof, they turned to the original tiles. “My father’s terrible at throwing things away,” Blee says. “We took the tiles off 30 years ago, as it was too dangerous to have them up there. They’ve been sitting in the fields ever since, and this was our last chance to use them.”

The home’s interior design, featured in Vogue and widely celebrated, was an unusual foray into residential surrealism by Le Corbusier and his cousin, Pierre Jeanneret.

With a few small changes and regular maintenance, existing buildings are some of the most sustainable around.

In this kitchen, an exposed brick wall stands out against the milky smoothness of the marble tile floors.

A raised pool in the northeast corner of the building provides relief on hot, sunny days.

Hektor is divided into four independent suits and a central communal area.

For a bit of elevation in the overwhelmingly horizontal compound, step onto the deck of the Stealth Barn. A strip of mowed grass delineates a path between the two structures; otherwise the grasses grow wild.

At a fraction of the size of Ochre Barn, Stealth Barn is just one clear shot down the hall from the kitchen to the bedroom. OSB is an even stronger part of the interior here evoking bales of hay.

The architect chose granite for the house’s base, zinc for its roof, and Scandinavian pinewood for cladding—all materials that complement the nearby gray stone building.

A Renovated Farmhouse in Denmark: This beautiful renovation has a classic Scandinavian feel and soft, but simple color scheme. From The Style Files.

Durable, economical, and easy to build, the simple A-frame was once the must-have midcentury vacation home. Today, the classic retreat has been propelled back to popularity, thanks largely to photo-centric platforms like Instagram and Pinterest. Read on for 20 charming A-frame homes that caught our eye.

You may think that a library has to be its own room, but books can be stored and read just about anywhere. Lining a hallway with books turns it into a library that you’ll walk through, and be inspired by, every day. Cabinets below provide extra storage and even a place to sit and read.

An office nook and library can participate in the open plan or disappear behind pocket doors.

In 1962, Skidmore, Owings & Merrill architect Arthur Witthoefft won the AIA's highest honor for a home he built in the lush woods of Westchester County. Having fended off a developer's wrecking ball, Todd Goddard and Andrew Mandolene went above and beyond to make this manse mint again.

Alex Gil and Claudia DeSimio created a duplex in an apartment building where they’d been renting for years in Brooklyn, New York, and set to work gutting the interior and adding a new rooftop addition clad in panels of Cor-Ten steel.

The Floating Farmhouse’s semitransparent addition has a roofline that matches the pitch of the original 1820s farmhouse. A porch, tucked under the side eaves, is cantilevered over a stream that runs through the property. Ikea loungers are illuminated from the interior by commercial gymnasium lights repurposed as pendant lamps.

Tom Givone's current weekend abode, nicknamed the Floating Farmhouse, is—so far—his capstone project, a synthesis of personal taste, material experimentation, and historically sensitive restoration: a living laboratory for how to bring the vernacular past into the present.

The north wall of the IST home functions as a cut-away, offering a peek inside an efficient yet cozy dwelling. Architect Peter Jurkovič built the home for a woman who had sold her flat in the big city of Bratislava and wanted something that reminded her of the village life of her childhood.

In the flat’s living room, midcentury modern art and furniture harmonize with the rich floor tiles, opulent molded ceilings. and original pine wood doors. Prints by Gordon Matta-Clark line the wall near a 1950s Danish dining table that’s paired with Eames chairs. A painting by Kuuti Lavonen hangs above a pink chair and ottoman by Ronan and Erwan Bouroullec.

The house’s new lime plaster walls, seen here in the courtyard, contrast with the old brick wall that divides the house from Kolasiński’s adjoining carpentry shop. Though the house itself is small, the outdoor spaces and furniture studio bring its total square footage to nearly 11,000 square feet.

The box-shaped extension plays off the familiar farmhouse typology, creating a series of intriguing contrasts.

For the bedroom, the designer selected a bed by Muji and floor lamps by Lightyears.

Their creative confections may ruin our diets, but we’re happy to be their taste testers anytime.

Light streams into the bedroom through walls of floor-to-ceiling glass. The windows are triple-glazed, creating a tight, eco-friendly seal.

In this sleek kitchen renovation in San Francisco, the kitchen backsplash is an easy-to-clean glass backsplash that mimics the glossy finish of the surrounding white cabinets. Painters accomplished the high-gloss finish on the cabinets of a kitchen in San Francisco by applying a coat of paint, polishing it with very high-grit sandpaper, repeating the process for each layer, then topping it with three coats of clear varnish. "It’s like an auto body," says builder Jeff King. "It’s incredibly beautiful." The island provides shelving space and storage as well as a second sink, an is topped with pietra grigio marble.

The architects’ two young children occupy this bright bedroom, furnished with Ikea beds. Another custom lamp illuminates the space.

Situated on a natural promontory in Coupeaux, France, the home’s plan and expansive windows open it to the beautiful surroundings outside.

The challenge of renovating an iconic midcentury house is surely a daunting one for any architect, but apply this formula to a Richard Neutra house, and the responsibility rises exponentially. This was the situation for Los Angeles–based architect Peter Grueneisen, founder and principal of Los Angeles–based Nonzero Architecture, who inherited the task of taking on significant updates to an already-altered Neutra—the 1949 Freedman House in Pacific Palisades, California.

Saved from demolition, stripped of awkward alterations, and faithfully restored, these rehabbed homes prove how timeless midcentury design can be.

The original home was preserved and renovated. In the front bedroom, a small window was replaced with a large painted-steel window seat, a favorite of the residents' grandchildren.

At the opposite end of the studio, Framework Architecture created a partially enclosed sleeping nook that is spacious enough to fit a full-size bed.

The large patio leads to a newly landscaped back garden. An expansive glass wall promotes seamless indoor-outdoor living. Inexpensive brick pavers were chosen for the rear patio; they offer textural contrast with the steel of the door, brick of the rear facade, and pale gray wood of the interior floors.
