Woodblok is a start-up in the development-construction industry that offers exclusively RE2031-compliant houses with the Passivhaus and Bâtiment à Energie POSitive (BEPOS) labels. They are 100% built in France in assembly units. This production method, known as « off-site construction », is actively supported by the government.

Price – Quality – Delivery

A Woodblok home is manufactured and pre-assembled 100% in France. This virtuous construction method, known as « off-site construction », is actively supported by the French government.

  • Installation in one day
  • Carbon footprint reduced by 70%
  • Energy consumption of no more than 1€/day

Since our beginnings in 2013, we have completed several POC projects recognized for their thermal and environmental performance. Building on this track record, our aim is to scale up with our range of comfortable, affordable, healthy homes with low environmental impact.

10 million new homes are to be built with an ECD class A by 2050, meeting the performance threshold of the RE2028 standards at least.
This represents 400,000 homes per year for a construction turnover of 50 billion euros.

Our ambition: to become the French Boklok of Passivhaus

The success of the Boklok company is particularly inspiring, with its model combining prefabrication and standardization. The result of a joint venture between Skanska and Ikea, Boklok offers houses delivered in kit form that can be assembled in one day. By cutting buildings into sub-assemblies or modules, the company standardizes construction and saves on quality, time and cost, while being financially viable.
