Set on one of Belgrano’s most distinguished corners, at the intersection of O’Higgins and Zabala, this exceptional 1942 mansion stands as a refined investment opportunity and a rare architectural treasure within Buenos Aires. Conceived as a grand Petit Hotel, the residence unfolds across four elegant levels, offering generous volumes, classical proportions, and an increasingly scarce layout in today’s market.
The property is introduced through a private main entrance with capacity for up to six vehicles—an extraordinary asset that enhances both functionality and long-term value. The ground floor is dedicated to service areas, including a spacious kitchen, wine cellar, mechanical room, and staff quarters, all seamlessly connected to an expansive garden. This verdant retreat provides privacy, tranquility, and a highly desirable outdoor setting rarely found in the neighborhood.
A private elevator and an imposing imperial staircase ascend to the formal entertaining level. Here, a grand reception hall opens onto an impressive living and dining area distinguished by oak wood floors, double-height ceilings, and ornate moldings finished in gold leaf. The fireplace serves as a focal point, framing open views toward the garden. A formal dining room for up to thirty guests is complemented by a secondary dining space with independent service access, ideal for high-end entertaining. A marble-clad guest powder room completes this level.
The private quarters occupy the second floor, accessed via the striking marble and bronze staircase illuminated by abundant natural light. Four bedrooms are arranged on this level, including two en suite suites and two additional bedrooms sharing a spacious bathroom, all finished in pink marble. The principal suite, exceeding 80 square meters, offers a walk-in dressing room, beveled mirrors, and a luxurious marble bathroom, reflecting the scale and elegance of the original design.
The upper level, accessible by elevator, features a large en suite space suitable as a bedroom or private study, opening onto a rooftop garden. This elevated outdoor area crowns the residence and presents a unique opportunity for boutique-style entertaining or quiet urban retreat.
An independent service staircase leads to the laundry area and four additional rooms with bathroom, originally intended for chauffeurs, further enhancing the property’s flexibility for residential, diplomatic, or hospitality-oriented use.

Preserved in excellent condition and distinguished by its generous garden, rooftop terrace, and architectural integrity, this mansion represents a rare and compelling acquisition—equally suited as a private residence, boutique hospitality concept, or long-term investment in one of Buenos Aires’ most established residential enclaves.
