A6A : H-eva

The team from the A6A agency - Atelier 6 Architecture - imagines an innovative concept: a prefabricated and mobile, sustainable and ecological microarchitecture, which they call H-eva. This small wooden house, to be installed everywhere, is a living space reduced to the essentials. Back on the genesis and the challenges of this innovative concept.

The H-eva house was born from the meeting between the developer of ideas Michel Calliau, the craftsman Nicolas Laveau and the architect Michel Hardoin.
In 2014, Michel Calliau and Christine Tanguy entrusted A6A with the construction of a wooden pavilion attached to their family home. Seduced by the wooden housing created by Michel Hardoin, the sponsor wishes to go further and develop a mobile and autonomous cabin. The initial idea finally took shape at the end of 2016 when the duo met the builder Nicolas Laveau, who has been thinking for several years about the manufacture of a prefabricated and ecological home.

H-eva is a contemporary cabin, of 20 square meters, which contains everything necessary to live there in a self-sufficient way: a main space, a private corner that can accommodate up to two double beds, a kitchen, a sanitary block - shower and dry toilets - as well as a wood stove and a technical cellar housing the water purification system and the electric batteries powered by the photovoltaic panels on the roof. Heated and lit in this way, H-eva is as comfortable as a conventional home and produces its own energy, without waste or pollution.

Built with sustainable and local materials - Landes pine or New Aquitaine wood - the hut is adorned with wooden planks from floor to ceiling, left rough inside and burnt outside. Also open to the landscape, this small pavilion has large bay windows, sometimes opening onto a terrace.
Today, H-eva is marketed on the site dedicated to the project. The acquisition of this house, the price of which varies between 30 and 000 euros depending on the options chosen, is closely monitored by the workshop team and depends on four preliminary stages: being certain of the site, defining its module according to its needs and budget, obtain the necessary authorizations for construction and validate the estimate. After its artisanal manufacture in the workshop, the house is transported to the chosen location by flatbed truck, then installed with a crane on site without altering the soil.

In addition to being a low-cost housing solution, H-eva offers its inhabitants an atypical spatial experience. Combining comfort and ecological awareness, the cabin offers them to return to their roots. The first model accessible for rental is located in the Basque Country (64) and available on the Airbnb platform.

Difficult not to be seduced by this small module, which opens the field of possibilities in terms of habitat and also allows to think of the house of tomorrow.
