About our name 

Quattrolibri derives its name from the architecture treatise published by Andrea Palladio in 1570, “I Quattro Libri dell’ Architettura”.


The « Four Books » illustrate the principles of simplicity, harmony and sustainability which embody the Palladian style.

We aim to apply similar principles to our projects.

A new Renaissance


The International Panel on Climate Change established the need to change the shape of our GreenHouseGas emissions growth curve.


This change implies significant modifications of our behaviour, consumption patterns, investment and equipment decisions.


Eco-design, energy efficiency, dematerialised growth, industrial ecology, collective action, carbon pricing and regulation are key drivers in what amounts to a new Renaissance (see: www.renaissanceecologique.fr).


Our goal is to help our clients build successful businesses built on such premises.
