Our world and its resources are finite. However, increasing demographics and urban densification will require the - rapid - deployment of quality infrastructure, that is developed for adaptability... and cost efficiency!

High Six was founded to offer a fresh methodology to long-standing challenges.

We are dedicated to the design and build of your low-carbon projects.

We drive the resilient construction of tomorrow's community

Our values

Our shared values are at the core of what we do: driving resilient construction to host tomorrow's communities.



We believe in the power of a collaborative ecosystem.

We work with trusted partners and we are open to learn, understand and integrate their solutions and proposals.

We are convinced that this method contributes to greater value creation.



Current working processes are flawed.

Too often it seems due to a lack of pragmatism and transparency.

In order to be build trust with our customers, project teams and and partners, our approach is honest and impartial.



To be a virtuous and responsible actor:

We design buildings that take into consideration the adaptability to change whether it is social, societal, climatic or in uses.

Our design and build practices are infused with circular economy principles.



We are passionate about the human aspect and technological innovation potential of the building industry.

This passion gave birth to great ambitions and strong desire to contribute to the evolution of the industry.

Aubin Balcerzak,
From working on site with his father carpenter to studying wood sciences and technology, Aubin has been surrounded by wood pretty much his whole life.

Since his first encounter with Cross Laminated Timber (CLT) in 2008, he developed a unique expertise in the mass timber building industry with experiences in design, engineering, sales and business development within pioneering and leading companies across Europe.

His strong interest in green building solutions and community places led him to codevelop High Six to bridge the two, to sustainably answer contemporary challenges.

Mathieu Lafargue,
Over 7 years in main contracting, Mathieu has developed an in depth understanding of construction processes from tender to handover.

His skillset encompasses design, procurement, contract and site management of all construction trades (especially civil works, façades and MEP).

Exposure to main methods of construction gave him the conviction that the industry needs to embrace ConTech and sustainable resources in order to improve its stagnant productivity and overcome its decarbonisation challenge, which will benefit construction's image and ecosystem as a whole.

In construction, if carefully managed, it could be this time a vector of salvation."
