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.

Stainless steel was selected for the kitchen countertops, and the pair relied on a local industrial sheet metal fabricator to help them prepare the material for residential application. The mix of warm and cool adds depth and dimension to the space.

Light from a new skylight pours into the home's entryway and living room. Steel columns and beams were added for structural reinforcement, and the couple left all beams, old and new, exposed.

"I always wanted to have my very own yellow brick road," says Viviana de Loera, whose favorite part of the home is the playful staircase. The original stairs and handrail were preserved in the renovation.

In the living room, and throughout the home, recessed "book nooks" are used to provide space-saving storage. The only seating in the room is a sleek black faux leather and steel daybed, fabricated by Montreal-based Surface Jalouse. Walls were removed to cohesively unite the living space and kitchen.

Jessica Helgerson Interior Design updated a split-level ranch house in Portland by introducing a clean white palette and vintage furnishings.

Rustic meets modern in this bedroom, where white track lighting beautifully illuminates a black wall and serves as accent lighting for vintage wall art.

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 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.

“A critical aspect of the project was the incorporation of natural light and ventilation within a broad footprint,” Simpson says. Conventionally private areas, like bedrooms and bathrooms, are therefore reinterpreted with more openness in mind. For instance, this bathroom’s skylights mirror those found throughout the rest of the property. The bathtub, basins, and showerhead were all purchased at the Australian retailer Reece.

The renovation revealed a 30-foot-deep well beneath the bedroom, which the team half-jokingly considered turning into a fish tank. Instead, they opted for a simple bedroom with plenty of built-in storage.

Designer Jeff Sand’s Universal Chairs combine his love for classic French café chairs with an appreciation for “the beautiful metal casings on an old Moto Guzzi.” Sand Studios also designed the dining table and pendant lamp.

Shibata made the 10-person dining table using $130 sawhorse legs from Maruki Wood Products Company topped with a sheet of birch plywood. A hole in the sliding wall fits over the table, enabling it to be used in both the library and the meeting room. malki.jp A movable wall clad in wainscoting on one side slides along tracks in the dining-room ceiling, dividing the room into a meeting space and a library.

Mark Fekete and Viviana de Loera, co-founders of interdisciplinary design firm MARK + VIVI, happily took on the challenge of building their dream home in a transitioning Montreal neighborhood. The couple's kitchen is an exercise in both sustainability and creativity. The island is wrapped with reclaimed scrap wood uncovered from the house during demolition. Chalkboard walls provide a whimsical canvas for graphic images and notes. Stainless steel was selected for the kitchen countertops, and the pair relied on a local industrial sheet metal fabricator to help them prepare the material for residential application. The mix of warm and cool adds depth and dimension to the space.

The chalkboard wall also acts as a sliding pocket door to the first floor bathroom. To maximize usable space, there are no hinged doors in the home's interior.

The clients for this the Alan-Voo house renovation and extension from 2007 are a couple with three daughters. The scheme—a 1,000 square foot addition to a 1,000 square foot house—leaves half of the house for the daughter’s bedrooms and incorporates the other half plus new extensions in front and back into a public zone and a private bedroom for the parents. This strategy amounts to a new 16-foot wide linear house being inserted into the existing house. Multi-toned, bright colors accentuate the new pieces which suggests a graphic expression representative of the family’s interests. Photo by Benny Chan courtesy of NMDA.

The master suite was fashioned from the house’s original garage in a 1970s renovation.

Locally sourced Canadian plywood was used for the flooring throughout the home, and all doors and windows were replaced with low-energy upgrades. The couple shares their space with guide dogs they foster through a local organization.

The only grouping of Frank Lloyd Wright's early American System-Built Homes—built by Arthur Richards and designed with standardized components for mass appeal to moderate-income families—is situated in the Burnham Park neighborhood in Milwaukee, Wisconsin. The four model 7A duplexes, one model B1 bungalow (shown here), and model C3 bungalow were added to the National Register of Historic Places in 1985.

"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 budget was nearly as tight as the space in this cheerful renovation of a 516-square-foot flat in Bratislava. The centerpiece of Lukáš Kordík’s new kitchen is the cabinetry surrounding the sink, a feat he managed by altering the facing and pulls of an off-the-rack Ikea system. The laminate offers a good punch of blue, and in modernist fashion, Kordík forwent door handles in favor of cutouts. “I wanted the kitchen to be one simple block of color without any additional design,” he says.
