Fighting the Housing Crisis in a Sustainable way

"Insanity is doing the same thing over and over and expecting different results." - Albert Einstein

Building systems have not changed in the past 100 years, Preflex is here to change that. The current construction industry accounts for 50% of the world's Co2 emissions.
This is a huge problem considering we have a housing crisis, meaning we will need to double our construction volume if we are to provide housing for all. To solve both problems, we must change the way we build.

Thanks to our state-of-the-art building system, Preflex leverages a revolutionary, streamlined process to build sustainably, in a fraction of the time. By manufacturing our system off-site, we provide high-performance building materials that are ready to assemble when they arrive on-site.
