The building was built in 1910. "It’s a pretty raw space with rough exposed brick, barrel vaulted ceilings, original hardwoods, and exposed ducting," Greenawalt says. "We tried to use industrial materials—stainless steel, perforated steel, brick—in a more refined way for the kitchen."

Upstairs is a sleeping loft, accessible by a spiral staircase. A digital projector makes it possible for the couple to watch movies against the opposite wall.

The home’s enclosed courtyard sits at “the heart of the structure,” says Baumann, who resides with his wife, Lisa Sardinas, and eight-year-old son, Oskar. “This is clearly the dominant space; everything flexes towards it.” Baumann cast the square concrete floor tiles himself, enlisting the help of his son. A small, neat patch of grass—a playful nod to the archetypal domestic lawn—is edited down to a charming folly.

When not in use as the headboard, the large redwood slab folds down to become a desk.

The Tower House is made up of tiny houses, clustered at the southern end of the property and clad in white steel panels and western red cedar shingles. Spinning off the living room on the north side of the main house, the children’s study sits separate from the other pavilions. On its upper level, Oxley netting forms a web on which the kids and their friends can sit and read with views of the leafy street and garden.

The bedroom is located on a mezzanine just below the roof of a church. The minimal decor and simple arrangement of the room reflect the client’s modest tastes. The small pewter spotlights and pendant by Holloways of London connect to an exposed galvanized conduit that is set against the brick above the bed.

The bedroom’s vertical, floor-to-ceiling window lets occupants admire the graceful trees outside. A Mini Tolomeo lamp by Artemide sits on the bedside table.

The Trues host parties in the glass-walled structure, located steps from their vacation home, or they escape to it to catch some rays and read a book. Bill reclines on cushions hidden under the reclaimed-fir floorboards that are propped up with Sugatsune hinges.

On Vashon Island, about 20 miles southwest of Seattle, architect Seth Grizzle designed a 440-square-foot multiuse structure for his clients Bill and Ruth True.

In an industrial neighborhood in Brooklyn, a verdant green roof of native grasses, wildflowers, and fruits creates an oasis.

The Gregory Residence is a masterclass example in design. Furnished by renowned New Hope woodworker George Nakashima, this private and rustic home offers ingenious versatility over its 1,644 square feet of space on a 10-acre lot.

This open-concept Amsterdam loft features soaring 15-foot ceilings, an Eames lounge chair and ottoman, and a Jielde light. Throughout the home, Standard Studio architects Wouter Slot and Jurjen van Hulzen favored raw materials, including concrete, oiled oak, and hot-rolled steel, all of which complemented the original space's industrial feel. Tucked smartly underneath the loft, a compact home office features functional built-in shelving and an Eames DSR chair.

Kartheiser’s private courtyard includes a covered seating area and fire pit, designed by Roberts.

To inform the color palette for this interior renovation in Stockholm, NOTE Design Studio began with three inspirational images. The sculptural fireplace, covered in plaster, contrasts with oak parquet floors.

Designer in Brooklyn, New York "The pieces in the space are a combination of industrial reclaimed finds and bespoke, often both in the same item. The cabinets were a vintage medical find, powder-coated and set up on welded stilts. The mirror was commissioned from Made In Chinatown. Ceiling color and texture came through lots of trial and error in order to avoid the heavily toxic and arduous process normally involved in staining concrete. The mezzanine sign which marks the space was acquired through a long chain of inside jokes from a friend—I'm still unsure exactly of its origins, possibly the bygone New York Subway signage system."

Uninterrupted cement flooring was chosen for the mezzanine. The cement extends to the bed and bathtub block, while the exposed ductwork and black beams above dramatically accentuate the ceilings.

A social creature who seems to know everyone, Loft J occupant Jamil Malone has hosted several "alcohol-themed" parties and manages to wedge as many as 20 people into his studio. The gatherings are like gallery openings, with the walls of Malone's apartment displaying a roving selection of locally produced art.

Roberts found the Montauk black slate, which he continued in a second bath.

Beneath a recycled-wood ceiling and centered by a Bokhara rug, the living area contains furniture of their own design.

The project’s unique challenges—a tight budget and steep, difficult terrain—led architecture firm _naturehumaine to a creative solution that gave the house its delightfully sculptural appearance. Making the first floor’s envelope slightly narrower than the top one’s saved money while minimizing the amount of excavation required.

The guesthouse hovers above the motor court. "The main area was broken up into four zones: the kids wing, the guest suite, the master suite, and the living-dining room and kitchen, which is a transition area, where public meets private," says Hawkins.

The architects stuck to a gray-scale color palette, installing slate tile floors that softly contrast with the white walls and Eames dining chairs. “It lets the views out the windows become the focus,” Dworkind explains. Doses of pure black accent important features, like the central wall that divides the kitchen and master bedroom behind it from the main living space.

In February of 2007, two San Francisco art and travel addicts purchased a 3,200-square-foot former Chinese laundry and tooth-powder factory with column-free interiors and a zigzagging sawtooth roof in lower Pacific Heights. They customized a pair of shipping containers to accommodate their collection and reflect their passions, and hired a local company to sandblast the interior to expose the board-formed concrete walls and replace the carpeted floors with Georgia hickory pecan planks to further lengthen the loft and make it look more like a warehouse.

"When I was furnishing the place, I made sure it’d also be a good place for art," Judin tells FvF. "After that, I considered my other passions: cooking, for example. My kitchen is the heart and center of the house."

Baumann designed the plywood bed frame and shelving unit in the master bedroom, adjacent to an exposed cinder-block wall, a new addition to the structure.

The house is oriented to maximize views of the ocean and Edgartown to the west, and Nantucket and Cape Pogue Bay to the east. Natural sea grasses sourced from the surrounding area cover the roof of the building, providing thermal insulation while also dampening the noise of rain, improving air quality, and helping to manage rainwater flow.

The Baumann family residence in Gowanus, Brooklyn, is all geometry up front, with a rectilinear grid of steel and cypress comprising the structure’s double facade.

The upstairs showers are particularly ingenious: Operable skylights loom above, and perforated, galvanized-steel platforms open up to spacious, sunken bathtubs.

Large sliding glass doors suspend the living room within the landscape for family gatherings or larger events.

The relationship between interior and exterior becomes crucial in the articulation of the residence.

The first floor consists of two long and narrow structures that intersect in an open kitchen, providing distinct programmatic areas and settling into the tree-lined landscape, allowing yards to surround and permeate each room.

When he moved in, Judin noticed that his existing furniture fit right into the new space—many pieces are also from the '50s. See more images here.
