boulogne-billancourt – 121 m2 interior + 137 m2 terrace – Historic houseboat with Seine & Parc de Saint-Cloud views

A unique and historic floating home moored at the autonomous port of Boulogne-Billancourt, just by the Pont de Saint-Cloud. This exceptional concrete-hull houseboat was originally commissioned in the 1950s by the polar explorer Paul-Émile Victor to demonstrate the capacity of floating concrete to support heavy loads. It was later used by the army’s health services for decompression chambers before being converted into a residence and divided into two independent apartments.

Surfaces & layout: Open and flexible spaces

This rear apartment on the boat offers 121 m2 of interior living space and a 137 m2 open-air rooftop terrace. The layout is smart and versatile, and includes:

-A large living space with lounge, dining area and wood-burning stove

-Open-plan fitted kitchen with island (sink, oven, induction cooktop, 2 refrigerators)

-2 comfortable bedrooms

-1 office/library (can be used as a 3rd bedroom)

-1 en-suite bathroom inside the master bedroom

-1 shower room with walk-in shower

-1 separate WC

-1 spacious utility/laundry room (can be used as office or dining space)
