This revamped Montreal flat includes a rooftop sauna lined with torrified, or dried, cedar. Outfitted with glass paneling and oriented to capture views of Mount Royal, it is the ideal haven for this hardworking homeowner.

Rydingsvärd often cooks out on his terrace, which offers a view of Mount Royal. The volume housing the sauna is clad in cedar planks that were painted black. The door and windows are by Alumilex, and the custom outdoor shower is by Avantage Plus.

The sauna is a decidedly Scandinavian touch.

The steel beam original to the building was left exposed but toned down with gray, flame-proof paint. It runs the length of the flat, delimiting the passage area.

A radiant hot water heating system was installed under a new concrete floor slab above the old foundation. It was coated with epoxy — light gray for the common areas, white for the bedrooms and bathrooms — then finished with matte polyurethane.

The ground-floor sauna, one of the home’s central gathering spots, is built from stained alder. The electric heater is from the Finnish company Iki.

The apartment originally crammed four closed rooms and a kitchen and bathroom into 1,000 square feet. After the renovation, it had only one bedroom and a large, open kitchen.

The same space before it was updated.

A 500-square-foot outdoor space with a grill, a table, and a hammock sits just off the entrance level of the townhouse, offering extra room for dining, relaxing, and entertaining. The corner couch is a custom piece inspired by the large cushions of Moroccan sofas. The Fermob table is paired with Hay Hee dining chairs by Hay.

If you’re looking for a modern retreat in an old-world setting, cast your sights on this charming loft in the west Berlin neighborhood of Charlottenburg, known for its distinguished selection of shopping, dining, theaters, and museums.

In the living room, spare Scandinavian design takes center stage. Hans Wegner’s Wishbone chairs surround an Essay dining table by Cecilie Manz for Fritz Hansen; a mostly wood palette is enhanced by slate-gray brick around the fireplace. The paper lanterns throughout the home are a mixture of classics by Isamu Noguchi alongside those picked up in Japan and France.

“We didn’t go out and buy a living room collection,” Sofie explains. “In our home, we tried to avoid trends. The furniture we have are things we have collected over many, many years.” Vintage Eames for Herman Miller lounge chair; Isamu Nuguchi table; and Rocking elephant by Rocking Zoo.

White was used extensively throughout the addition, a choice that the architects say enhances the spacious feel of the rooms and draws attention to the views.

Modern Murphy beds like this one often incorporate sleek lines constructed in dark-toned woods.

No whiteware here. In this moody apartment in Berlin, multi-toned charcoal gray subway tiles make up the backsplash, which contrasts with the pop of rosy color on the kitchen cabinets.

Piet Hein Eek's wooden chairs add a touch of color to the monochromatic Amsterdram apartment of Hunter Hindman and Shelby Carr.

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.

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.

The renovation of a 2,000-square-foot property updates a century-old design for a family of four. "We placed the kitchen at the center of the house to link with the dining room and the outdoor space," Moreau says. In the kitchen, a Wolf oven brings out the silver details in Coit’s Bianco Cararra backsplash and island. Hee bar stools by Hay are lined under the island.

Van Dusen began making her own clothing as a teenager after convincing her mom to buy a sewing machine she'd use to reconstruct her closet full of thrift store garments. Color was her primary muse, often favoring bright hues in unexpected combinations and graphic patterns. What she couldn't find, she created, albeit inefficiently — the only way she knew how — by assembling her own printed textiles, one element at a time.

The semi-closed entryway contains a white cabinet for storing coats and scarves. The LED ceiling lights are from Contrast Lighting.

The architecture firm L. McComber Itée demolished a sloping ceiling in this Montreal attic to create a bright, roomy live-work space.

A short wall on the kitchen island hides clutter and keeps the straight lines of the design unmarred. Almost every lighting fixture, including the overhead Artemide Tolomeo light, is movable. The refrigerator and oven are from Fisher and Paykel.

The renovated attic is oriented around a central volume that houses the bathroom. The wooden shelves were fashioned from hemlock planks that were salvaged during the demolition of the roof structure.

The renovated house is outfitted with a sauna.

Lisbeth Juul and Laust Nørgaard drew upon their years of experience living on the water to design and build an 860-square-foot floating home in Copenhagen Harbor. The home’s minimal form and furnishings reflect the residents’ desire to downsize following three years on land.

Since the front door is located in the exterior wall, residents first enter a vast garden before reaching the gable roof house.

Sofie and Frank built a box around an ordinary glass fiber shell bathtub, then covered it in a mosaic of shower tiles. Natural light from a large dormer window gives the tiles an almost iridescent glow. The toilet is Duravit.

Since Copenhagen is generally cold, the house was painted black to trap warmth. The result was that in its first year, it consumed so little energy that the client received a generous refund from the heating company. “Many wooden houses in Scandinavia use this trick,” Larsen says. “On sunny days it even radiates warmth, so that in spring and autumn you can sit outside by the wall and in this way extend the outdoor season by a few weeks every year. These weeks are valuable in places with little light.”

The kitchen features a distinctive cantilevered countertop.
