To most eyes, Ezequiel Farca’s 1970s-style concrete home in Mexico City looked like a teardown. Even the lot itself—shallow and crammed against a steep hillside—wasn’t particularly alluring. But Farca saw through all the restraints to create a spa-like refuge in one of the world’s most energetic cities. "It’s is such a hectic place. You’re bombarded by so much information the moment you step into the streets," says Farca, who first gained prominence as a furniture and interior designer. "So we envisioned this house as a retreat, a kind of a temple." The rooftop courtyard is lined with a verdant mix of indigenous plants, including banana trees, palm trees, lion’s claw, Mexican breadfruit, and native vines. The chaise longues were designed for Farca’s EF Collection.

In the outdoor dining room, wire chairs by Harry Bertoia for Knoll surround a mango wood table made by a local carpenter, Diego Madrazo.

The family's activity centers around the open-plan dining room, which does triple-duty as a living room and kitchen. Susanna prefers a motley set of dining chairs over a coordinated set; that way guests can pick their favorite when they sit.

The renovation, which focused on the living-dining-kitchen area, strikes a balance between intimate and inviting, hence the project's name, the Open/Private apartment.

Known for furniture and interior design, Ezequiel Farca transformed a 1970s-style concrete home in Mexico City into a tranquil sanctuary. The temple-like retreat blends into the hilly Lomas de Chapultepec neighborhood with its pale gray-green hue and strategic plantings, which soften the boundaries between house, garden, and street. The Recinto lava stone patio accessed through the living room holds teak outdoor furniture designed by Farca himself.

"The longer I work as an architect, the more I want to deepen my skills as a gardener," says Yuri Zagorin Alazraki, founder of the Mexico City firm ZD+A. In building his own house in Mexico City’s Lomas de Chapultepec neighborhood, his commitment has produced results that appear miraculous. In fact, they grow out of a carefully choreographed series of bravura design moves.

Two smaller, adjacent structures house autonomous bedrooms, each equipped with a full bathroom.

In an effort to create an abundance of light and air flow throughout the space, the home follows an L-shaped floor plan that wraps around outdoor areas. “We designed several open spaces, each with a different feel: the garden and pool, the terrace, and the back patio,” says Cesarman. “The idea was to reduce the area to the most basic and essential [elements].”

Joaquin Altamirano and Silvia Martín worked with Daniel Bergman Vázquez of Estudio Untercio to create an open-plan oasis in an apartment building in central Madrid. Estudio Untercio designed the medium-density fiberboard cupboards, which are coated with lacquer paint matching the ceramic-porcelain countertops. The tubular hood above the island is by Teka.

Solid European oak flooring by DuChateau runs throughout the home. The sculpture is by Jorge Yázpik.

Farca furnished the living room with a Serge Mouille three-arm floor lamp, custom sofas from EF Collection, and Surface tables by Vincent Van Duysen for B&B Italia.

A couple—he an entrepreneur working in logistics, she a stay-at-home mother—bought an 8,500-square-foot house here and approached JSa, a Mexico City-based architectural firm, with the idea of remodeling it. The house was poorly sited on its lot in a manner that drew very little natural light. The architects sized it up and quickly realized that the best solution would be to tear it down and start from scratch.

Nakada works from an Alvar Aalto table in the living and dining area, adjacent to the kitchen. He saved on some elements, such as the plywood cabinetry, and splurged on others, such as the Finn Juhl chairs and Vilhelm Lauritzen lamp. A skylight beneath the angled roof allows in a sliver of constantly changing light.

Farca also designed the custom millwork throughout the house, such as the swinging door leading into the dining room. The leather Siren dining chairs are by Holly Hunt.

The refrigerator is Sub-Zero, the cooktop and hood are Viking, and the oven is Miele.

The central living area features an open-plan kitchen, living space, and deck with views of Louttit Bay. To maximize energy savings, the house has a ducted reverse air cycle system from Fujitsu.

The decidedly modern dining and kitchen areas open to the backyard through a floor-to-ceiling steel-and-glass door, fabricated by Optimum Window. One of the owners’ favorite features of the home is the “ability to connect the inside to the outside seamlessly,” Bangia describes. The living area serves as “a place for the kids to dance or ride a skateboard, a casual space that reflects the way they live.”
