The Carré d’Or and Orangerie feature mansions priced between €2M and €9M, with stable value despite inflation. Robertsau and Contades concentrate architect-designed family villas (€1.8M to €6M). Our firm, located at 91 route des Romains, supports resident and international buyers in strictly off-market transactions.

In-depth analysis

Carré d’Or: The Heart of Strasbourg’s Prestige

The Carré d’Or refers to the quadrilateral formed by Place Klein, Place Saint-Pierre-le-Jeune, Quai Kléber and Rue de la Mesésange. It hosts 18th and 19th century mansions (up to €9M), penthouses on the Ill with cathedral views (€4M to €7M), and large apartments on noble floors (€1.2M to €3.5M).

Specific taxation: half of the Carré d’Or lies in the Bâtiments de France zone and is classified as UNESCO World Heritage. All building permits require approval from the ABF, which protects value but complicates renovations.

Market: 87% off-market for sales over €2.5M (data 2023-2025).

Orangerie and Contades: The Garden Residence District

Bordered by the Orangerie Park (Strasbourg’s largest urban park), this area features classic French bourgeois villas: 350 to 800 m², gardens from 600 to 1,800 m², garages, and former outbuildings.

Prestige range: €2.8M to €6M. Ultra-prestige (within the park, direct view of Pavillon Joséphine): €7M to €12M.

Contades, immediately adjacent to the park, combines quick city centre access with absolute tranquillity. It is the preferred district for Alsatian business leaders, senior European officials, and physician homeowners.

Robertsau: Residential Luxury

As Europe’s largest residential district by area, Robertsau houses the German Embassy, the Council of Europe headquarters, and numerous architect-designed villas from the 1920s-1960s and contemporary styles.

Range: €1.5M to €4.5M, with some signatures (influenced by Le Corbusier, Tony Garnier) exceeding €6M.

Major advantage: average garden size of 1,200 m², three times larger than Orangerie. Excellent ecological health (proximity to Robertsau forest), low traffic density.

Krutenau and Petite France: Confidential Noble Properties

Krutenau (students + young professionals CSP++) and Petite France (touristic yet ultra-prestigious on the Ill) offer extremely rare properties: renovated timber-framed houses, industrial lofts, converted artist studios. Typical prices range from €800K to €3.2M. Strong buyer demand, few public listings.

Frequently Asked Questions

Everything you need to know before your project

What is the average price of a Carré d’Or mansion in Strasbourg?

Between €2.2M and €7M depending on size (350 to 800 m²), condition (renovation needed or turnkey) and view (Ill or cathedral = +30%). Properties over €9M are rare but exist (about 5 transactions per year).

Is there a real estate bubble in Strasbourg?

No, unlike Bordeaux or Lyon, the Strasbourg market remains undervalued by around 35% compared to comparable regional capitals. The presence of European institutions cushions any correction.

Are there any specific rules for purchases by non-residents?

No legal restrictions (buyers from EU, CH, UK, US are welcome). Non-residents must declare the source of funds (TRACFIN, AML). Our legal team prepares this documentation in advance. Capital gains tax applies at the local rate plus intermediate levy (tax mandate).

What rental yield can be expected on prestige properties in Strasbourg?

2.2% to 3.1% gross in the Carré d’Or, 2.8% to 3.8% in Robertsau / Orangerie. Low but stable, with capital appreciation of 4% to 6% per year over 10 years observed (DVF + Bas-Rhin Notaries data).

Who are the best notaries in Strasbourg for prestige properties?

We work with a panel of 3 notaries specialised in prestige heritage in Strasbourg. Identification is provided to our clients under mandate. All have over 15 years’ experience with properties over €2M.

Is the Carré d’Or classified under ABF?

Yes, the entire historic centre of Strasbourg (Grande Île) is UNESCO World Heritage and subject to ABF (Architects of the Buildings of France) regulations. Every façade, roof and opening is regulated. This explains the scarcity of available properties.

Can you assist me if I am a client of Lacaze, Engel & Völkers or Sotheby’s?

Yes. We work alongside these seller agencies. Our mandate is exclusively buyer-focused, providing a balance you do not have with a seller agent alone.
