Penthouse
Definition, Characteristics
and Exceptional Properties

Exceptional top-floor apartment, private terrace and panoramic views — everything you need to know about penthouses, from their definition to their market in France and internationally.

The penthouse is the epitome of urban luxury—a property that combines the attributes of a detached house (space, private outdoor space, privacy) with those of an exceptional address atop a prestigious building. Its scarcity is inherent: there can only be one—or at most two or three in the largest buildings—per building. This absolute rarity, combined with sustained international demand, gives the penthouse a particularly strong long-term asset value.

Definition

What is a penthouse?

The term penthouse comes from the English word "penthouse"—itself derived from the Old French "apentis" (lean-to), which originally referred to a structure built against a wall. In contemporary usage, a penthouse designates an apartment located on the top floor of a building, featuring a large private terrace, panoramic views of the city or surrounding landscape, and above-average ceiling height.

Confusion often arises between a simple penthouse apartment and a true penthouse. Not all top-floor apartments are penthouses. A true penthouse is distinguished by several key features that go far beyond its location within the building.

A penthouse is the entire top floor of a building — or a large part of it — transformed into a unique residence, with a private terrace, private access and high-end amenities. It's not simply an apartment "at the top".


Features

The characteristics of a luxury penthouse

A penthouse is defined by a set of cumulative criteria. The absence of one or more of these elements may call into question the property's classification as a true penthouse.

🏙️ Exclusive top floor

The penthouse occupies the top floor(s) of a building, often in its entirety. It has no upstairs neighbors — this is one of its fundamental values.

🌿 Private terrace

A large terrace — often several tens to hundreds of square meters — is the defining element of the penthouse. It can be designed as a rooftop garden, outdoor pool, or reception area.

🌅 Panoramic view

A 180° or 360° view of the city, the sea, or the surrounding landscape is a key factor. A penthouse without an exceptional view loses most of its value.

📐 Ceiling height

High ceilings — often 3 to 5 meters — give the penthouse generous volumes that radically distinguish it from standard apartments.

🛗 Private access

Private elevator or separate entrance directly from the lobby — the penthouse guarantees absolute discretion and privacy for its occupants.

✨ Exceptional services

Private pool or jacuzzi, advanced home automation, chef's kitchen, wine cellar, home cinema, spa — penthouses concentrate the most exclusive amenities on the residential market.


Penthouse vs. Attic

Penthouse or attic — what's the difference?

Apenthouse simply refers to an apartment located on the top floor of a building, often with a small terrace. It's a common architectural term that doesn't imply any particular level of amenities. A penthouse can be a standard 50 m² apartment with a 5 m² balcony.

The penthouse is a different category altogether—it involves a generous living area (often 150 to 500 square meters or more), a large terrace (sometimes larger than the apartment itself), high-end amenities, and an architectural design that makes it a truly unique residence within the building. The price difference between the two can be a factor of two to five.

Market & Price

Luxury penthouse prices in France

Penthouses are the most expensive residential properties per square meter in any real estate market. Their structural scarcity—only one per building—and sustained international demand maintain prices that can be two to three times higher than those of apartments in the same building.

🗼 Paris — 7th, 8th, 16th
€15,000 – €50,000/m²
Records in Saint-Germain-des-Prés. Views of the Eiffel Tower, the Seine or the rooftops of Paris as a decisive bonus.
☀️ French Riviera — Cannes, Nice, Antibes
€12,000 – €30,000/m²
Records in Cannes — over €32 million for a 447 m² penthouse on the Croisette. Sea view = considerable premium.
🎰 Monaco — Mareterra & Monte-Carlo
€50,000 – €100,000+/m²
Monaco is the world's leading market per square meter. Mareterra exceeds €100,000/m² for new penthouses overlooking the sea.
🍷 Lyon, Bordeaux, Aix-en-Provence
€6,000 – €15,000/m²
Markets experiencing strong growth. Lyon and Bordeaux offer contemporary penthouses with roof terraces at still affordable prices.
🌊 Marseille
€5,000 – €12,000/m²
Views of the Mediterranean, the Old Port and the Frioul Islands. A rapidly developing market driven by the rehabilitation of the quays.
🏔️ Alps — Courchevel, Megève
€15,000 – €40,000/m²
Ski-in/ski-out penthouses in the most exclusive resorts reach price levels comparable to Paris.

A penthouse in a prime location can command two to five times the price per square meter of a standard apartment in the same building. The terrace, the view, and the uniqueness of the property are the main factors contributing to its premium value.

Advice

Buying or selling a penthouse — what you need to know

For the buyer

Purchasing a penthouse requires careful attention to several specific points. Waterproofingthe terrace is a critical expense—large terraces can develop significant leaks if maintenance has been neglected. Condominium fees can be significantly higher than those of other apartments in the building, particularly due to the upkeep of private amenities (swimming pool, dedicated elevator).

The shared roof space also necessitates careful attention to thermal and acoustic insulation—a poorly insulated penthouse can be difficult to heat in winter and overheat in summer. Finally, planning regulations may limit the possibilities for terrace design (height of low walls, installation of pergolas, planting).

For the seller

Showcasing a penthouse relies on the quality of its visuals —sunset terrace photos, nighttime city views—which are often decisive factors in the purchase decision. Listing on luxury real estate portalslike Propriétés De Charme guarantees exposure to a qualified clientele rather than a high volume of untargeted inquiries.

Discretion factor for penthouse buyers — a confidential sale, without public display, corresponds to the expectations of a clientele that seeks precisely the intimacy that the penthouse embodies.
