The custom cedar tub, fabricated by Dovetail, elegantly fits into the master bathroom.

The walnut staircase and slide in a Chicago town house leads from the main level to the basement. To protect people on the ride down, a “crash pad” fashioned from a standard gymnastic mat covers the wall at the slide’s base.

The Lowreys worked with architect Luis Sánchez and a team of local craftsmen to complete the build. The custom counters in the kitchen are terrazzo and granite; the oven and cooktop are from Teka.

Hynam built additional storage along one angled wall of the bedroom loft and beneath the skylight.

Bernier’s firm designed the built-in storage, seating area, and kitchen island to be intentionally abstract, directing attention to the forest outside. Cabinetmaker Pixel & Scie manufactured the furniture.

Custom kitchen cabinets designed by Pulltab and fabricated by Maciek Winiarczyk hold mostly vintage ironstone that Geiger has found at flea markets and estate sales over the past 20 years. "I love white," she says, "because I think food always looks better on it." She also collects vintage wooden cutting boards, shown resting against the marble tile backsplash from Stone Source.

In the master bath, a custom raised Silestone sink is surrounded by a teak countertop and Porcelanosa glass tiles. Teak slats anchor the glass-enclosed shower.

The former dining room is now home to Russell and Fontanez’s custom kitchen, designed by LOT-EK and fabricated by Chef Restaurant Supplies. “We love to entertain,” Russell says. “Before, the galley kitchen was in the hallway; now we can cook and still be a part of the party.” The space-saving setup, which adjoins the living room, features stainless steel–paneled cabinets, DuPont Corian countertops, Onda stools by Jesus Gasca for Stua, and fixtures and appliances by Grohe, Liebherr, and Miele. To maximize space, the designers specified that the cabinets be built around a former fireplace in the kitchen. “Because there’s a bump out where the chimney is, we turned the sink lengthwise,” Lignano says. “The cabinet directly overhead is only four inches deep, so it’s just a huge spice rack.” The island provides ample additional storage.

The bedframe, also custom and seen here without a mattress, rests in the center of the living space and offers almost panoramic views.

“Gatherings here can be a very rich experience, a dis-cussion around art history, music, food, and fashion.”—Kenneth Montague

When JAC Interiors was commissioned to revive an old 1,200-square-foot Hollywood home, the clients—a young couple who the designers call "fun and quirky"—requested the firm find a way to transform the space with as little construction as possible. The fireplace is a custom-made, three-dimensional feature that stands in stark contrast to the soft woods and white walls that make up the rest of the room.

A 3,500-square-foot home in upstate New York was designed by the architecture firm Mapos with simple materials and passive design principles. The contemporary fireplace, which sits on buffed concrete flooring at the center of the ground floor, was custom-made by Mapos.

The house’s dominant gable form repeats at a smaller scale throughout the dwelling, as in the kitchen’s plywood and steel cabinets. “The gable became thematic throughout the process,” Maynard explains. “Whenever issues arose, we referred back to it as a default, rather than adding a new idea." The sink is by Abey, faucet by Franke, and range by Qasair.
