Structure:

A reinforced concrete   roof circular  and hollowed out in the center  to act as well of light , supports also various elements which ensure in whole or part the autonomy of the dwelling . It rests on 7 interdependent posts between them and thus dividing space into 7 sectors.

The posts connected to the higher part by a lintel   supports the technical passages (water, electricity, telephone, network, etc....). Each post hollowed out in the center, allows the water run-off   of rain towards the reserves in basement. . In each post, reserves close to the periphery allow the descent of the cables and/or pipes or necessary. An adjustable space is spared between this lintel and the roof forventilation .

With the lower part in basement, the posts are connected by armed partitions  being able to act as water tank in whole or part of surface . The whole of the posts, roof, lintel and partitions armed with the basement form the rigid structure of the dwelling. The unit rests on a concreted flagstone reinforced according to the ground, with the right of each post by a drilling even concreted to him. In order to increase seismic resistance further, the whole of the structure is just posed on this concrete flagstone.

Frontage:

In withdrawal of the roof ,la frontage located at the edge external of the lintel can be builds into traditional or in modular elements  Chaque module can comprise: carry, travelling window, bay, ventilation, shutters according to interior installation. By the cylindrical total form, resistance to the cyclones is some increased compared to standard elements used in a conventional house.  According to closings' chosen, certain sectors can be completely open on outside .

The frontage can be re-examined with the liking of the years without attacking the structure of the dwelling, therefore without decreasing its resistance.

Installations:

Interior space can in the form of loft  or be divided into many parts  connected between them towards the center, around an aquarium  (or another decorative space) making enter the light by the transparent roof in the center. Moreover, the center of each sector receives the natural light by  a transparent dome  amplified by effects of mirrors .

With the liking of the ground chooses and of its tastes, each consecutive sector can be on a level growing until forming additional sectors in stages, or a stage in crown can be envisaged, by envisaging posts simply  higher.

Autonomy:

The electric power is partly assured by a wind mill of which the axis is interdependent of an interior blade  brewing the air of the dwelling. At the same time, it involves a moteur/dynamo reloading batteries to continue ventilation in absence of wind. The roof can also support photovoltaic panels indirectly connected to the electrical supply network in order to control its needs by achat/vente for electricity  .

The rainwater stored in the lower tanks is initially pumped on the level of the roof, is purified , then distributed cold in the house or heat while crossing solar collectors . This oversize solar collector    can be divided to also heat the water of a swimming pool or the house by the ground in low temperature  . From its circular and tilted form, this sensor always has a directed part in an optimal way, it is enough to a small accelerator connected to a solar panel to balance its temperature and to decide automatically to connect it to the reserve of hot water thanks to the differential thermostat, when its temperature is higher. According to the latitudes and seasons', the less exposed part can benefit nevertheless from the sun  by directional mirrors.

The whole of the technical parts located in roof is masked by a flower stand located in offset at the periphery makes also hood for all the frontage  .

In addition according to the area, of the solar collectors with hot air  can take part in the heating or the ventilation of the house according to the position of a simple shutter. Moreover the air flow can come from a Canadian well, bringing fresh air in summer and air moderated in winter.
