House Boat

House Boat®: a concept designed to adapt our construction methods to flood-prone areas

Located on the Savoie Technolac site, in a flood-prone area, this inland port where ten house-boats are moored hosts cutting-edge companies and business incubators.

The beauty and uniqueness of the site led us to conduct a sensitive architectural study, enabling the integration of tertiary activities in harmony with a natural environment that must be preserved.

Built with lightweight metal frames on stilts, their simple construction method makes them flexible and versatile. Arranged here in a comb-like layout around a central pier, this concept can be adapted to other sensitive sites by modifying the composition.

Intentions – Design Approach

The House Boat layout is simple, modular, and extendable in length. The open-plan design and exterior walkways offer great flexibility in terms of use. The interior can be adapted to suit various programs: enclosed offices, open-plan workspaces, storage areas, workshops... the combinations are endless.

The buildings are arranged in a comb-like pattern around a central pier, to which the access walkways and exterior corridors are moored. Made of lightweight, demountable metal frames, the walkways are constructed from zinc-coated steel to reduce weight and minimize corrosion.

Large glazed openings throughout the structure capture solar energy in winter, while generous roof overhangs provide natural shading in summer, enhanced by the surrounding woodland trees.

This is a very simple building: the walkway allows for easy cleaning of the windows, while the roof overhang shields from the sun and its slope directs fallen leaves straight to the ground—no gutters needed. The design is entirely guided by use and functionality.

That summer, I was alone at the office, calm, open to ideas shaped by sensations. It was then that I realized continuing the landfilling would be a mistake. It would be far more interesting to elevate the buildings, to place them above the lakeside landscape.

The atmosphere, a subtle mix between constant interaction and an ability to maintain the level of calm necessary for work.

Here, the atmosphere strikes a subtle balance between constant interaction—which helps everyone work better and faster—and the calm needed for focused work.

The spaces also make it easy to create moments of conviviality. A shared kitchen and terrace, open to all, allow for afterwork gatherings or informal meetups.

This project responds :

To the need for flexibility from the various companies present.
To the wish of some independent workers to be able to work in a place that preserves the serenity of their home while allowing them to meet other professionals.
To the request of local authorities or public bodies wishing to offer a new model (compared to business incubators and business centers), with modern and more attractive solutions for entrepreneurs.
To the possibility of building in regulatory-constrained areas with significant flood risk.
