With just 4,900 square feet, the single-story historic house could absorb only a fraction of the hotel’s program: reception, lounge, restaurant, bar, kitchen, meeting space, and five guest rooms. A 34,100-square-foot addition of four floors and a basement accommodates 27 more lodgings and a spa. “Before we commenced construction, the zoning changed to permit more height,” recalls von Werz. “We briefly studied the possibility of adding a level but abandoned the idea, as the building started to feel out of sync with the urban context and the domestic scale of the villa.”

The site has an irregular, polygonal shape. An old redbrick wall encloses the sides and rear, formerly occupied by sheds and workshops. At the front, the historic house borders the promenade, its L shape anchoring the lot near its northwest corner. Von Werz’s scheme for the addition was simple and direct: a second L-shaped building at the southeast corner, whose oblique angle he finessed with a circular stair. “The two volumes complement each other,” says the architect. “Together they form a coherent whole, a perimeter construction that loosely frames a central courtyard.” Other outdoor spaces include a pool court and gardens along the property’s edges, and Grupo Habita’s signature rooftop bar (as seen in RECORD, December 2011, June 2013, and February 2017).

The addition rises as a stack of four boomerang-shaped tiers made of reinforced concrete. At the ends, the tiers cantilever and step back to reduce mass and provide generous terraces. “They evoke nautical images of a cruise ship’s deck,” says von Werz, recalling his client’s request. The spaces between slabs are punctuated at 18-foot intervals by walls clad in acetylated wood that frame large planes of glass, enclosing guest rooms set back behind private balconies. The contrast between this bold modernist composition and the classically articulated villa is striking. But the two buildings coexist harmoniously because both are finished in white-painted stucco and share a horizontal rhythm. One floor of the new building aligns approximately with the cornice of the old, establishing a subtle continuity along the street.

Materials throughout draw on the original detailing of the house, including artisanal terrazzo and Talavera tiles, hand-finished wood lattice and millwork, and blown-glass lamps in both clear and amber tones. “The atmosphere of the existing building was so strong that it became the common thread for the whole project,” says Paula Alvarez de Toledo of JAUNE. Almost everything except bathroom fixtures and fittings—and door handles designed by von Werz’s former employer David Chipperfield—was fabricated in Mexico, much of it nearby. “Grupo Habita steers away from importing products and consistently wagers on the local,” says von Werz.

The architect minimized the need for air-conditioning despite the hot, dry climate. The concrete floor plates reduce solar heat gain by providing substantial shade on balconies and outdoor corridors, where permeable screens of lacquered steel fins facilitate cross ventilation. Water features provide evaporative cooling in outdoor spaces.

“La Paz has mainly two types of visitors,” says Couturier. “High-end travelers arriving in private jets and heading straight to their yachts, or independent travelers who love nature, hiking, pristine beaches, or kitesurfing. We see our hotel as a social hub where these two groups connect.” With its sophisticated layering of new and old in a setting that juxtaposes natural splendor with urban vitality, Baja Club seems certain to attract both sets of clientele. Too bad Jacques Cousteau can’t join them.
