The project
Julien and Aurélie lived in a three-room flat on the 7th floor, with no lift, in the 16th arrondissement. With two young children and a double pushchair, daily life had become unworkable. They wanted to leave inner Paris for more space and, above all, private outdoor space, which had become non-negotiable. Boulogne-Billancourt was the natural choice: right beside the 16th, good schools, green space, and prices per sqm that brought a property with a garden within their budget.
The search strategy
Our property hunter focused on three micro-neighbourhoods in Boulogne-Billancourt: Silly-Galliéni, Billancourt-Rives de Seine and the area around Parc de Billancourt. The garden requirement made the search unusual: this kind of property is rare and often sold before it is even listed. The search paired standard monitoring of listing portals with fieldwork, direct contact with the managing agents of complexes that have garden-level units, and the local agency network for priority alerts.
The property found
The flat is in a quiet 1975 residential complex in Silly-Galliéni, 8 minutes on foot from the Marcel Sembat métro station (Line 9). The 85 sqm ground-floor unit has a 30 sqm living room with direct access to the 40 sqm private garden, three bedrooms (13, 11 and 9 sqm), a separate fitted kitchen and a bathroom with bath. The south-facing, enclosed garden suits children perfectly. The residence is well kept, with a concierge, bicycle storage and cellar. Monthly charges are 280 euros.
The negotiation
The asking price was 775,000 euros, or 9,118 euros per sqm excluding the garden. The technical analysis turned up several points: windows needing replacement (estimated at 12,000 euros) and a dated bathroom needing renovation (8,000 euros). Combined with comparable transactions within the complex (two sales at 8,200 to 8,500 euros per sqm over the past 12 months), these justified an offer of 710,000 euros. After negotiation, agreement came at 720,000 euros (8,471 euros per sqm). The 55,000 euros saved comfortably covers the renovation budget.
What this mission illustrates
Properties with private gardens call for a proactive search. In Boulogne-Billancourt, ground-floor units with gardens are taken up by family demand within days. Without prospecting on the ground and a local network, this kind of property stays invisible to buyers searching alone.
Technical analysis creates negotiating leverage. The 55,000 euros obtained rested partly on a factual reading of the coming renovation costs. A property hunter who views methodically turns defects into quantified arguments.
Boulogne-Billancourt offers Parisian families a better quality of life. For the price of a three-room flat with no outdoor space in the 16th, this family secured a four-room flat with a garden in an equally well-connected area. It is a trade-off more and more families make with a property hunter’s help.

Frequently asked questions
What is the average price per sqm in Boulogne-Billancourt in 2026?
Boulogne-Billancourt has an average price ranging from 8,200 to 10,500 euros per sqm depending on the neighbourhood. The Prince-Marmottan area is the most expensive, while the south of the commune towards Pont de Sèvres remains more affordable at around 7,800 to 8,500 euros per sqm.
Is it better to buy in Boulogne-Billancourt rather than the 16th arrondissement?
For an equivalent budget, Boulogne-Billancourt generally offers 15 to 25% more floor space than the 16th arrondissement, along with access to green spaces (Bois de Boulogne, municipal parks) and a family-friendly feel. Métro Line 9 connects both areas directly.
Can you find an apartment with a private garden in Boulogne-Billancourt?
Yes, but these properties make up less than 5% of available stock. They are found mainly in 1960s-1980s residential complexes and in recent developments. A property hunter with a local network spots these opportunities before they are publicly listed.
How long does it take to find a 4-room flat with garden in Boulogne-Billancourt?
In this mission, Home Select found an 85 sqm four-room ground-floor flat with a 40 sqm private garden in Boulogne-Billancourt in 8 weeks, and negotiated it from 775,000 to 720,000 euros, a 55,000 euro saving. As ground-floor garden flats are rare (under 5% of stock) and snapped up within days by family demand, the timeline depends mainly on fieldwork and a local network of building managers and agents. Without that access, a buyer searching alone may take several months.
