Living with outdoor space in the Hauts-de-Seine

The Hauts-de-Seine at a glance

The département is what Wikipedia calls a "département-ville": almost entirely urbanised, apart from its parks and woods. Its prefecture is Nanterre, and it has three arrondissements: Nanterre, Antony and Boulogne-Billancourt. Its highest point is in Vaucresson, at 180 metres, and Mont Valérien, at 162 metres, is the most visible height of the central escarpment. The Seine crosses the département, borders 17 of its 36 communes and is spanned by 36 bridges.

La Défense, the business district in the north, holds the Grande Arche and extends over Courbevoie, Puteaux, Nanterre and La Garenne-Colombes. Boulogne-Billancourt is the only commune with more than 100,000 residents. Neuilly-sur-Seine is among the communes with the highest median incomes in the département. About 150,000 people study here, at the University of Nanterre and several grandes écoles.

Parks, gardens and views

The Parc de Saint-Cloud, a 460-hectare national estate mostly within Saint-Cloud, hosts large music festivals. The Parc de Sceaux and the Meudon forest are among the roughly 1,500 hectares of woods and parks in the département. The Domaine national de Saint-Cloud runs along the whole southern edge of Garches, and the Malmaison state forest, with the Bois de Saint-Cucufa, lies to the west.

Each commune has its own spaces. In Boulogne-Billancourt, Parc Edmond-de-Rothschild covers about 15 hectares and the Albert-Kahn garden occupies the Parchamp district. Île Seguin, the former Renault industrial site, covers 12.3 hectares. In Neuilly-sur-Seine, the commune holds most of the Île de la Jatte, and the Bois de Boulogne borders its east and south sides. In Malakoff, Parc Léon-Salagnac and the Coulée verte du Sud parisien run through the town. In Fontenay-aux-Roses, Parc Sainte-Barbe covers 18,000 m². In Le Plessis-Robinson, Parc Henri-Sellier and the garden city built between 1924 and 1939 occupy the former château lands.

For anyone looking for outdoor space, this is what sets the département apart from Paris. Houses are less rare than in Paris: PAP publishes a house price for each commune in its table. A park or wood nearby partly makes up for the lack of a private garden. A balcony looks onto its surroundings: an avenue, a courtyard, a garden or a wood. A view that is advertised, over the Seine or a park, is to be checked at a viewing, at several times of day.

Towns worth knowing

Four groups of towns give an idea of the département. The prices quoted come from PAP (DVF and PAP, 1 October 2026) and from Efficity, for each whole commune, all districts together.

• Neuilly-sur-Seine and Levallois-Perret
• Boulogne-Billancourt and Courbevoie
• Saint-Cloud, Sèvres and Garches
• Montrouge, Malakoff, Fontenay-aux-Roses and Le Plessis-Robinson

Transport and daily life

RER lines A, B, C and E, trams T1, T2 and T6 and several metro lines serve the département. Lines 1 (La Défense, Pont de Neuilly), 3 (Levallois), 4 (Montrouge), 9 and 10 (Boulogne-Billancourt) and 13 (Malakoff) extend the Paris metro. Transilien lines L and U serve Saint-Cloud, Sèvres, Garches and La Défense. Journey times depend on the commune and the district: work out the walk to the station before viewing.

How prices vary

In the Hauts-de-Seine, the gap between communes is considerable: the eleven averages surveyed by PAP run from €4,251 to €10,500 per m², more than double, while the département as a whole stands at €6,466. Neuilly-sur-Seine is 62% above PAP's départemental average, Levallois-Perret 41%, Boulogne-Billancourt 29% and Montrouge 11%, while Fontenay-aux-Roses is 34% below.

Buying in the Hauts-de-Seine

The département mixes pre-war buildings, garden cities, residences from the 1960s to the 1980s, town houses and detached houses. Before buying with outdoor space, read the co-ownership rules, the minutes of the last three general meetings and the maintenance logbook: a balcony gets repaired, a terrace gets waterproofed, a façade gets renovated, and that work is voted on by the co-owners. For a house, check the plot, any easements and the local urban plan. Include notary fees in the budget too.

Selling in the Hauts-de-Seine

Comparables vary a great deal from one commune to another, sometimes from one street to another. Your buyer has seen them, and will ask why your price sits above the commune average. A balcony, a terrace, a garden or an open view must be shown in photos and measured: outdoor space is counted separately from the Carrez surface. The form at the foot of the page lets you ask for a valuation.
