Passionate about cut stone, or more exactly stone cutting, but also  through the architecture of historical monuments, I knew as soon as I entered the Saint Lambert school in Paris that I was going to spend my life learning, but also transmitting knowledge. Son of an Italian immigrant who, once he arrived from his native Sicily and after having demonstrated his know-how,  became a recognized Parisian entrepreneur. Married to a French native of Sologne where  Tuffeau stone is  the  component  unavoidable  in this region  from  constructions of  castles like that of Selles-sur-Cher.  I then discovered that the French and Italian cultures  were mixing  in a common cauldron united by  the passion for architecture  .

​​

The Saint Lambert school created  in 1899 are still forming  quantity surveyors but  for a better understanding, he became the one  construction economist. Although very widespread, it remains little known because whoever exercises it,  works in the shadow of architects, companies.  His work  consists  to encrypt in such a way  specify the  cost of  construction or renovation of  buildings,  based on a thorough knowledge of the construction technique. This knowledge and my experience have fueled my  imaginary  to create the concept  Cubeco.

​

Stone being a heavy and very expensive natural material nowadays, so I think  to a lighter and cheaper material.   Which material was closest to stone?  Cellular concrete. He  was going to haunt my nights, until the day when my imagination pushed me to want to create the impossible  : How to build in aerated concrete  lower cost with today's thermal constraints?  

​

Following the visit of a cellular concrete manufacturing plant,  I imagine a robot climbing the walls with these blocks. On the train that brings me back  in Paris,  I sketch on my notebook plans for the construction of a house and  in parallel  the factory of  future.

The idea is self-evident, you have to build modules like a vehicle production line. I draw up my first house plans with modules and  I start the technical calculations with a design office to perfect this solution. The calculations are  complex and after  five years of study and  changes,  the feasibility of the concept  Cubeco  is established. I draw up factory plans  with the location of the robots and  today  the technique is confirmed by a  integrator and  supplier  robots.

With the collaboration of a  of the best specialized firms  in Paris, a patent application was  filed in January 2020 under number 20 00379  at the INPI.

I would especially like to thank the  General director,  Samuel Le Cacheux  Engineer from the Special School of Public Works, Building and Industry (ESTP)  and  Marie-Robert  Graduate  from the Polytechnic Engineering School of the University of Tours  and  graduate of the Center for International Industrial Property Studies (CEIPI)  For their  audience  and their valuable advice in protecting my invention.
