It’s time to discover the story of
THE BUILDUP GROUP
BuildUp is, first and foremost, a story of innovation.
The BuildUp journey began with beSteel and lightweight steel frame. A decisive turning point came with the creation of BuildUp, marking the start of a broader vision—from energy-efficient renovation to modular construction, all with the goal of transforming the industry for good.
What if we transformed construction together?
BuildUp is reinventing construction, energy-efficient renovation, and modular housing through sustainable, innovative, and circular practices.
With a presence in Belgium, the Netherlands, and France, BuildUp is driving change in a long-static industry. Through its brands—beSteel and Retrofitt—the group offers efficient and environmentally friendly solutions, accelerating the transition toward sustainable construction.
It’s time to build, renovate, and expand like never before.
Build to last, Impact to Inspire
Our mission is to build to last while inspiring a positive and lasting impact in the construction industry.
Let’s go back to the beginning – 2015.
Founded in 2015 as beSteel, specializing in lightweight steel frames, the group has grown steadily to become BuildUp.
