The rear facade. A system of sliding glass windows and doors underscore the indoor/outdoor nature of the house.

Although little was done to alter the building’s original form, the firm did demolish an extension that was the site of a mechanical plant. This alteration allowed for an outdoor deck covered with timber decking by Chemisys Group.

A COZY AND MODERN INDOOR-OUTDOOR BEDROOM IN BUENOS AIRES In Argentinean architect and furniture designer Alejandro Sticotti's bedroom, dappled sunlight and reclaimed-wood floors and walls give the room a warm, peaceful feel.

Jason lounges in one of two armchairs by midcentury designer Milo Baughman in the parlor-floor living room. The wood block coffee table is by Eric Slayton, a friend of the couple, and the modular Carmo sofa is from BoConcept. A 1952 piece by French industrial designer Serge Mouille, the Three-Arm Floor Lamp—widely referred to as the "Praying Mantis," for its looming trio of arms—is a nod to the couple’s love of Parisian interiors; a branch-like chandelier by Los Angeles–based artist Gary Chapman hangs overhead.

Suzanne’s bridge and book clubs meet around the dining table in the cottage instead of in the larger house, whose open layout makes such gatherings problematic. “There was no place where I could seal us off,” Suzanne says. “So now I use the cottage for game playing, and we can enjoy ourselves and know that we’re not inconveniencing Brooks.”

Tehrani designed the millwork throughout, collaboratingwith fabricator C. W. Keller + Associates. Seen from the foot of the central staircase, a set of blue, gray, and yellow Alphabet sofas by Piero Lissoni for Fritz Hansen furnish the family room on the first floor; the dining area lies just beyond, adjacent to the kitchen. A small aperture provides a peek into the second stairwell, which is situated at the center of the floor plan and leads to the garden level.

A cooktop and refrigerator from Gaggenau, Bulthaup cabinets, a Miele oven, and an Asko dishwasher outfit the all-white kitchen, which is located on the entry-level floor.

In renovating a historic brick home for family friends in Washington, D.C., architect Nader Tehrani of NADAAA used ordinary plywood to reconceive the central staircase. Lined with a series of striated, geometric panels, the resulting structure is lit by a polygonal skylight above. Tehrani also designed the Pentavola table—featuring five sides, one for each member of the family—which they use as a communal workspace on the second-floor landing.

The firm used white materials throughout the renovation. The walls, ceilings, and woodwork are painted white. Portuguese Estremoz marble is featured on the ground floor.

Natural materials are contrasted with the white surfaces.

The patio at the front of the house offers a view of the balcony that connects the second-floor bedrooms.

The main living area is flanked by green spaces, with custom sliding doors made from materials sourced from a metal warehouse. The ceiling is corrugated sheet metal, a “common and cheap but noble” construction material, Teresa says.
