Vestack, a French start-up innovating in the (highly polluting) construction industry.

Vestack is a French start-up created in 2019 with the objective of contributing to the fight against climate change by constructing buildings with a low carbon footprint.


To do so, it uses bio-based materials (derived from renewable organic matter -biomass- of plant or animal origin) to design modular buildings for real estate developers.

These buildings are energy efficient and adapted to extreme climatic conditions, thanks to the use of digital design software.

The company finances its growth with impact funds to accelerate its development. Given the success of the concept with developers and social landlords, the company opened a second site in France in early January 2023. The aim is to double its teams to focus on more complex projects, such as large open spaces or new products such as thermal insulation on the exterior of buildings.


Buildings are responsible for nearly 40% of the world's greenhouse gas emissions, so it is crucial to make them more eco-responsible.


By using bio-based materials and prefabricating buildings in kit form, Vestack manages to reduce CO2 emissions by an average of 60%, without any additional cost for real estate developers.

The company's owner and co-founder, Sylvain Bogeat, emphasizes that this is possible thanks to the industrialization of the construction process and an optimized logistics flow.


One of the methods used by Vestack is passive construction, which involves maximizing the use of natural light and heat to reduce energy consumption. The startup uses elegant and functional designs to maximize the use of space in its buildings, making the most of available floor space.

In addition to constructing eco-friendly buildings, Vestack is also committed to using sustainable materials and minimizing construction waste.

The buildings are 90% assembled off-site, which reduces truck traffic by a factor of 5.


This company clearly shows its commitment to a sustainable economy and thus promotes environmental benefits in favor of biodiversity, such as green roofs and facades which are then transformed into an urban refuge for wildlife.

In addition, since construction sites are very short, there is few waste, noise or pollution for local residents.


Let's remember that construction is a very polluting sector: the manufacture of concrete, construction waste, chemicals used in building materials and greenhouse gas emissions, negatively affects our planet.


It is important that businesses and governments take steps to reduce this impact by adopting sustainable practices and regulating construction activities to protect the environment.
