House Boulogne-Billancourt - 4 bedrooms - 475m²

Île Saint-Germain. Hidden from view, in one of the most secluded settings on the outskirts of Boulogne-Billancourt, this spectacular architect-designed house by Pascale Creux offers nearly 475 m² of light-filled space, opening onto greenery and the Seine (275 m² of living space and 200 m² of converted basement).

Built in 2005 at the heart of a 400 m² garden, this detached property has a rare atmosphere: a contemporary home conceived as a true family residence, where every space connects with the outdoors. Surrounded by greenery and lulled by the tranquillity and reflections of the river, it seems suspended between nature and architecture.

The impressive proportions are immediately apparent. The light-filled reception areas rise to almost five metres at their highest point and open generously onto the garden and the Seine. The sitting room, dining room and spacious kitchen with dining area form a spectacular, flowing and welcoming space, extended by large south-facing terraces.

The house is arranged over several levels with remarkable fluidity. A mezzanine provides a study overlooking the reception areas, while the principal suite has its own south-facing terrace—a private retreat opening onto the greenery.

The sleeping accommodation comprises five bedrooms and three bathrooms. An independent studio, integrated into the house but with its own private entrance, offers a range of possibilities: guest accommodation, offices, a self-employed business or a space for teenagers.

On the top floor, an exceptional landscaped terrace of nearly 130 m² offers completely uninterrupted views over the rooftops, the Seine and the Eiffel Tower. This spectacular rooftop terrace, with no overlooking properties, features a pergola, a sunbathing area and a hot tub, and is designed as an additional open-air living space.

The lower level further enhances the property’s unique character. An indoor swimming pool, home cinema, spacious games room, large utility room and impressive wine cellar create a floor entirely devoted to comfort and spending time together.

Two outdoor parking spaces complete this exceptional property.

Just a few minutes from central Boulogne and Parc de l’Île Saint-Germain, as well as schools and transport links, this property brings together qualities rarely found on the market: no shared walls, exceptional proportions, abundant natural light, independence, open views and privileged access to the Seine.

A contemporary villa with the feel of a holiday home, with the Seine as its garden and Paris on the horizon.
