A few steps from Le Bon Marché—at the center of Paris’s most discreet and competitive residential micro-market—this 18th-century Paris mansion sits hidden behind a private courtyard and bordered by two exclusive-use gardens. Now priced at €13,500,000 and listed with Paris SIR (Propriétés Parisiennes) , it offers a rare expanse of quiet space and interiors with an unmistakable French country charm, ready for a thoughtful next chapter.

An 18th-century mansion hidden behind a private courtyard near Le Bon Marché.

Tucked away at the end of a paved, flower-filled courtyard, the property sits in a part of the Left Bank that has always felt slightly apart from the rest of the city. Between the 6th and 7th arrondissements—where quiet residential streets meet galleries, bookshops, cafés, and the steady rhythm of everyday Parisian life—the setting carries the kind of familiarity long-time Parisians value. Being a short walk from Le Bon Marché, that understated marker of true Parisian address, reinforces its position within one of the most desirable pockets of Paris luxury real estate.

Two private gardens—each roughly 300 m² (3,229 sq ft) and held in exclusive use—frame the home on both sides, creating an envelope of greenery that feels almost improbable this close to the center. In recent years, the 6th and 7th have seen especially strong demand from buyers drawn to Paris for its walkability, cultural life, and architectural authenticity. Properties with meaningful outdoor space are exceptionally scarce here, and homes near Le Bon Marché or Rue du Bac often remain in the same families for generations. When a historic Paris home of this scale appears on the market, it signals a quiet shift in a district that normally sees very little turnover.

**What Is the Carrez Law?**
The Carrez Law is a French legal standard defining the exact habitable floor area of a property. It excludes non-livable spaces such as walls, staircases, basements, and any area with a ceiling height below 1.8 meters (5.9 feet). Because it focuses strictly on usable space, the Carrez measurement often differs from the total floor area disclosed.

The main house spans 267.39 m² (2,879 sq ft) on the ground—234.30 m² (2,522 sq ft) under the Carrez Law—and unfolds across three levels, with the ground floor oriented entirely toward the gardens. A dining room and a 33 m² (355 sq ft) living room open directly onto the terraces, while a 20 m² (215 sq ft) sitting room draws the eye toward the second garden, creating a natural flow between indoors and out. A bathroom with toilet, guest toilet, kitchen, and laundry room are discreetly set into the wings of the house, preserving the overall calm of the layout.

Upstairs, the primary bedroom rises to cathedral-height volumes and includes its own bathroom, dressing room, and mezzanine—an interior profile that pairs naturally with the home’s understated French country character. Two additional bedrooms, each with its own bathroom or shower room and toilet, sit opposite a practical storage and ironing space.

A through-view office crowns the top floor, overlooking both gardens from above—an atmospheric vantage point that could also serve as a fourth bedroom. This level includes another bathroom with toilet, a dressing area, storage under the eaves, and a secondary mezzanine tucked beneath the roofline.

At the far end of the second garden, a renovated guest house of 33.22 m² (357 sq ft) on the ground (32.72 m² / 352 sq ft Carrez) offers a bedroom, shower room with toilet, and an office—an appealing arrangement for guests or a private workspace set apart from the main residence.

Three cellars and a nearby parking space complete the offering. With its north–south exposure, sheltered courtyard entrance, and uncommon dual-garden layout, this Paris property with gardens reflects a form of Left Bank living that rarely reaches public view. Very few private homes in Paris offer this much space—indoors and out—while remaining deeply connected to the daily life of the 6th and 7th, moments from Le Bon Marché and the Bac–Sèvres corridor.

In a district defined by long-held addresses and quietly significant architecture, this 18th-century Paris home stands apart for its authenticity and the rarity of its footprint. It is the sort of property people wait for, often without knowing exactly what they’re waiting for—until something like this appears on the Paris luxury real estate market.
