House B autonomous won the Sustainable Construction Grand Prize of the 2019 Green Solutions Awards at the Maroco level + the international Sustainable Construction Grand Prize.


This house has been conceived as a true bioclimatic greenhouse , offering a south facade in double glazing , free to hide thanks to a system of shutters whose positions are managed by jacks. The north facade is completely buried in a mound planted . The house was built with a wooden structure and filled with mud bricks . All in total autonomy : photovoltaic electricity, recovery of rainwater in a buried tank and filtration for domestic and drinking water, treatment in phytopurification for all dirty water. The modular layout of spaces and furniture in the entire house, allows many combinations and adapts to the seasons and the number of occupants. Thus, the living space during the winter is reduced to maintain thermal comfort ; during the summer the house opens and frees up space. All the components of the house have been designed and manufactured on site (windows, kitchen, handles, furniture ... etc.) The different living areas of the house are not assigned to a single function, it is the user who will define it, according to his desires of the moment, by moving the furniture on wheels, by sliding walls, leaving appearing "hidden" furniture ...

Owner approach of sustainability

We have always been particularly aware of the overconsumption in which we were evolving, and in which we ultimately participated. But, taken by our urban daily life away from these considerations, we were totally inactive. When we decided to build this house, our primary concern was not ecological. It was mainly about creating an exceptional place, a bubble of serenity that would allow us to escape the chaos of our daily Casablancais. It seemed obvious then that this house would finally be the opportunity for us to assume our environmental responsibility and to reduce, on our scale, our footprint on the environment.

The idea was then to prove to ourselves but also to serve as proof that aesthetics, design and quality of life were not exclusive of environmental responsibility.

It was after our meeting with Myriam and Laurent, at home in Felfla, that we understood that we could push this idea even further. They made us taste energy autonomy, we were seduced.

Architectural description

The house wants to be stealthy and integrated into its environment. The entry of the house is located north facade, a breakthrough in a mound planted ... At first we do not guess the house, we must cross to see it appear south facade as a discreet object that came to ask gently without impact on the ground. We discover a multifunctional removable facade constantly changing over the days and seasons. These large shutters, according to their deployment, serve at the same time insulators and sun breeze, they extend the terrace and offer integrated seats and blinds. Site Implementation Strategy and Materials:

-House oriented North / South, talute on its facades North, East and West, to increase the global inertia.-Bearing walls in adobe, the ground being taken on the ground.-Structure and chaining in fir tree: balance compensated by the trees planted on the site.-Wood exterior cladding, to protect the raw earth.-Finishing lime plastered fine, without adding paint.-Large greenhouse on south facing wall accumulator contiguous to living spaces.-Removable facade multifunctional.-Reduction / expansion of spaces during extreme weather events (extreme cold or heatwave).

If you had to do it again?

Since the first autonomous housing in Medina Rabat, inaugurated in 2013, we do not offer more than that to our customers, the results are beyond our expectations and we are convinced that these systems are viable and should be generalized to any construction.

Building users opinion

Today, more than a year after our installation, we are still very (pleasantly) surprised to find that we live quite "normally" and our daily needs are fully covered by the energy that the house produces.

From a thermal point of view, at no time, we felt the need to install an air conditioning, the rooms are at all times of the year very pleasant (cool in summer and temperate in winter) and the fireplace is very efficient in winter. The temperature difference with houses in conventional construction at the same time is noticeable.

Health & Comfort

    All spaces benefit from natural light, through sliding glass panels, glass roofs, skylights ... All these openings include concealable panels or baffles, to be oriented according to the entry of light desired according to the day and seasons, thus ensuring circulation and renewal of the air.

    Buried house and earthen walls allow a good absorption of the sounds and a very good acoustic comfort.

    Finishing work / Exterior joinery - Doors and Windows

    This principle makes it possible to manage the light inputs as it sees fit, and thus to control the interior temperatures of the house. not only is it a facade element but it also extends the veranda, serves as a sunshade, insulation, cushion range ... when they are inclined, they also serve as seating in chaise lounge mode.

    More than just a part, this innovation is an integral part of the overall concept of the house and was immediately accepted. The execution by the various carpenters was carried out without problems. The only difficulty was rather electric in the choice of cylinders and their installation ...

Cette maison a été conçue comme une vraie serre bioclimatique, offrant une façade sud en double vitrage, occultable librement grâce à un système de volets dont les positionnements sont gérés par des vérins. La façade nord est complètement enterrée dans une butte plantée. Des puits de lumière avec déflecteur sont présents dans les chambres. La toiture est isolée avec du liège et la ventilation se fait naturellement assurant le confort thermique.
Cette maison se compose d'une structure bois et de murs en briques de terre crue façonnées sur place, les enduits sont en chaux/sable et tous les éléments ont été fabriqués au Maroc (fenêtres, volets, systèmes d'ouvertures, cuisine), le but étant d'utiliser un minimum d'objet usinés et importés, en privilégiant le local.
