50th Annual Meeting of the World Economic Forum

UHCS will be at the World Economic Forum in Davos to discuss access to quality housing and more from the 21st to the 24th of January 2020

An alternative to traditional materials

UHCS is a patented modular construction system developed in Switzerland made of recycled PET. By recycling the available non-biodegradable PET into modular construction structures, UHCS provides an economical and technical solution to face the international housing crisis while decreasing the impact of human needs on nature. UHCS is designed to be easily and industrially produced in large scale by extrusion or 3D printer, and is composed of 3 main profiles that assemble as in a Lego game to form walls, floors and ceilings organized under a cubic structural standard which is suitable for infinite architectural compositions adaptable to local cultural traditions.

How does it work?

Upcycling of plastic waste

UHCS – recycles or more so upcycles the international PET plastic wastes.

Accessibility to habitat

UHCS – renders accessibility to habitat, and encourage local circular economies.

Itself recyclable

UHCS – is a construction system that is itself recyclable to serve future human needs.

The energy potential of our houses


A modular construction system which resembles a building block game. A set of beams and walls made of recycled PET filled with a foam of the same material.


The use of plastic waste gives this material a second life. Its recycling holds out the promise of a healthier world, saves the oceans and enables buildings that are themselves recyclable to be put up.


The calculation is very simple. Taking the raw material price, the extrusion cost and the cost of the structural work of the house itself, a module of 11.6 m2 costs around CHF270.–/m2 in Switzerland. Generally self-sufficient in energy thanks to the use of solar panels, each house can sell on its surplus electricity production.


The evident valorisation of PET and other plastic materials makes the system inherently ecological. We do not throw away or destroy: we transform. What is more, after around 80 years, each dwelling that has come to the end of its useful life can be recycled again or destroyed with a minimum impact on nature.

Igor Ustinov

A prestigious sculptor who has designed monuments in several big European cities, creator of the “Benois de la Danse” at the Bolshoi, a classical singer and holder of an MPO degree in biology from the University of Paris VII.

Igor Ustinov has worked for artists on the Board of Directors of the ADAGP. He founded and inspires several foundations and associations. He presides over the “Sir Peter Ustinov Foundation”, named after his father, which is active on behalf of children, the “Ustinov Institute” which fights prejudice and the “Ustinov Prejudice Awareness Forum Association” which conducts an open debate about the negative effects of prejudice and the importance of respect as a value for social progress and for the environment.  

He is a member of the Executive Boards of the “Winds of Hope Foundation” created by Bertrand Piccard, the “Carène Foundation” and the “Pro Valat Foundation.”

Apart from his active commitments, primarily structured in his “Ustinov network”, Igor Ustinov is first and foremost an artist, a creator!

André Hoffmann is Vice Chairman of Roche Holding Ltd. Alongside his non-executive roles in the family business, he has a distinguished cursus in nature conservation and sustainability. He is the President of the MAVA Foundation of the Tour du Valat Foundation in the Camargue region, France. He has joined the Board of SytemIQ to help positively disrupt critical economy systems; the Board of Trustees of the World Economic Forum and the Center for the Fourth Industrial Revolution in San Francisco. He is Chairman of the Advisory Board of the Hoffmann Global Institute in Business and Society (HGIBS) at INSEAD.

Through his multiple initiatives, Mr. Hoffmann is attempting to influence business thinking towards the long term by pushing companies to not only report on financial guidelines but also on their real contribution to society in environmental and social terms.
