Selling a Maison de Maître or Art Nouveau Townhouse in Brussels in 2026: Make the Most of Your Heritage

Selling a townhouse in Brussels is not like selling any other house. Mouldings, herringbone parquet, stained glass, the original staircase: what gives a maison de maître its charm also makes it more complex to sell. You need to showcase it, answer questions about energy performance and heritage status, and reach the buyers who are willing to pay for that character.

The market remains supportive. According to the Belgian notaries’ barometer for Q3 2026, the average house in the Brussels-Capital Region sold for €609,227 over the first nine months of 2026, 4.8% more than the 2025 average. The number of houses sold, however, fell by 1.8%: buyers are more selective, and preparation makes the difference.

What gives a Brussels townhouse its value

Buyers of this type of property are first buying an atmosphere. Four elements weigh most in their decision.

• Original features: marble fireplaces, mouldings, ceiling roses, joinery, tiles, sgraffiti, ironwork. Their condition matters as much as their presence.
• Ceiling height and the light in the interconnecting rooms, often over 3 metres on the main floor.
• The garden: in the city, a south- or west-facing garden remains a rare asset.
• Overall coherence: an intact single-family house is often worth more than one split into flats, provided its planning situation is clear.

The same reasoning applies to Art Deco heritage, which we cover in our article on Brussels Art Deco and today’s property market: authenticity commands a premium, as long as it is well documented.

Listed, safeguarded or on the heritage inventory: constraints and advantages

Before putting the house on the market, check its exact status. In Brussels, three situations coexist, and they do not have the same effects, according to urban.brussels.

Status	Legal protection	What it means
Listed (classé)	Yes (CoBAT)	Works require a single permit, possibly with advice from the Royal Commission for Monuments and Sites; subsidies and a possible exemption from property tax
On the safeguarding list (liste de sauvegarde)	Yes (CoBAT)	Same legal basis as listing, with constraints on works
On the heritage inventory	No	Recognised heritage value, taken into account in permit applications, without any guarantee of conservation

For a buyer, protection is both a guarantee and a constraint. A guarantee, because the setting and the neighbourhood are preserved. A constraint, because works take longer. For a listed property, regional subsidies can cover up to 80% of studies and up to 40% of maintenance and restoration works on the protected parts for a private owner. That is a selling point worth highlighting.

The status appears in the urban planning information. Use it to check that no planning breach could block the sale, as explained in our guide to urban planning information in Brussels.

The EPC of an older house: anticipate rather than endure

A house built around 1900 rarely has a good energy rating. That is not a deal-breaker, but it must be anticipated. The EPC (PEB certificate) must be drawn up before the property goes on the market, the energy class and consumption in kWh/m²/year must appear in the listing, and the certificate is valid for 10 years, as Brussels Environment points out. Administrative fines range from €50 to €62,500.

Buyers also look ahead. The Region is aiming for a ceiling of 275 kWh/m²/year for homes by 2033, roughly today’s F and G classes, with exemptions still to be defined (RENOLUTION). For a character property, the right answer is a costing: a few quotes for roof insulation, a new boiler or double glazing compatible with the original frames reassure far more than words. All the details are in our article on the EPC and selling in Brussels in 2026.

Selling a townhouse in Brussels: finding the right buyer

The high-end market is active, especially in the south of Brussels. According to an analysis by Christie’s International Real Estate of FPS Economy data, reported by La DH, Uccle recorded 99 sales above one million euros in 2025 (+24%), including 84 houses, at a median price of €1.3 million. Ixelles and Woluwe-Saint-Pierre follow, along with upper Forest and Auderghem. The same analysis notes that energy-inefficient properties remain harder to sell.

Three buyer profiles often come back for an older Brussels house:

• families looking for space and a garden in a green municipality;
• architecture lovers, ready to restore and attentive to original details;
• professionals who want to combine a home and a practice, provided the permitted use allows it.

For a high-value property, you also need to choose between wide marketing and a discreet approach. We compare both strategies in our article on selling a luxury property in Brussels.

Photos and staging: show the character

A townhouse sells first through its images. A few simple rules:

1. Shoot in natural light, through the interconnecting rooms, to show depth and height.
2. Dedicate close-ups to the details: stained glass, fireplaces, parquet, door handles.
3. Declutter without emptying: a few well-placed pieces of furniture give the rooms their scale.
4. Add a floor plan for each level: over three or four storeys, buyers must grasp the layout at a glance.
5. Write a listing that tells the story of the house: architect, year of construction, remarkable features.

The goal is for viewings to take place with buyers who are already won over by the character of the house, and who have already seen the EPC and heritage status.

Frequently asked questions

Conclusion: get the price right before selling

Selling a townhouse in Brussels requires a valuation that takes into account what price grids ignore: the condition of the original features, the heritage status, the real cost of energy works and the depth of the market in your municipality.
