BuildUp

A chapter closes for BuildUp, but beSteel Light steel framing keeps moving forward. 🏗️

After several months of reflection, BuildUp has decided to cease its operations, closing an important chapter in offsite construction. This marks the end of a journey that began in 2021, driven by a strong conviction: the construction sector must radically transform to become more frugal, more precise, and more circular.

To promote this bold industrial model, we took risks — but we were unfortunately unable to overcome all the challenges we faced, particularly those linked to rapid growth, perhaps too rapid. While the BuildUp brand fades today, the innovation we championed continues to move forward.

beSteel carries on. 🤝

We are very pleased to announce that the assets of beSteel (founded in 2015) have been transferred to the company SWEELCO, created and led by Damien Muller and Pierre Rougeulle.

This transfer allows beSteel's historic expertise to endure and find new momentum. By joining Sweelco, beSteel becomes part of a structured and ambitious industrial project built around a shared mission: to design and produce every day "light & smart" constructive solutions.

Thank you to all those without whom this adventure would not have been possible:

✨ Hélène de Troostembergh, the driving force and face of BuildUp and beSteel. Her determination, vision, and unwavering commitment — right up to the closing of this chapter — deserve special recognition.

🤝 The BESIX Group and the de Troostembergh family, for their constructive collaboration and their support in the face of the challenges of innovation.

🙏 Our teams, who gave all their energy and talent to this extraordinary adventure.

beSteel's historic expertise is now in good hands, at Sweelco, to continue carrying high the ambition of "Reconstructing Construction for Good."

You’re wondering what this is all about?

🎟️ Come see for yourself.

On September 18, we will be on stage ! 20 minutes to explain why it’s time to build… differently and Beyond Tradition. Beyond ego. Beyond business as usual.

🗓️ September 18 - full day

📍 Reset Brussels

Back to work. Back to building. Back to buildUp. 👷‍♂️👷‍♀️

Helmets on. Machines running. Computers switched on.
We’re energized, focused, and ready to build faster, smarter, and better than before.

Because challenges don’t wait.
And neither do we.

Let’s get to work. 💪

Paper plans are cute... until they get rained on. ☔

We’ve all been there, squinting at a wet floor plan on-site, trying to make sense of something that was never meant to be built that way.

At BuildUp, we said enough to guesswork, delays, and avoidable mistakes.

So we built a process that’s 100% digitally driven, from first sketch to final screw.

Here’s what that looks like:

📌 BIM modeling for crystal-clear planning

📌 Point clouds & laser scanning for precision

📌 Automation in design & production for real efficiency

The result?

✅ Projects delivered faster

✅ Less waste , more sustainability

✅ Fewer “wait… what?” moments on-site

We believe the future of construction is digital and you ? What do you think ?

When we say fast, we mean 🚀 one house a day fast.

Compared to traditional methods, we’re up to 60% faster. How?

✅ We only drive to the site once (no back-and-forth chaos)

✅ Everything’s built and assembled in-house, rain or shine

✅ Fewer delays, more precision, better results

With BuildUp and Retrofitt, renovation isn’t a headache - it’s a quick win.

💡 Fast, clean, and ready to go.

Think construction can’t be clean and green? Think again.

With offsite building, we cut down on:

🌱 Transport emissions - one trip to the site, not ten

🌱 Waste - precise production = fewer materials wasted

🌱 Build time - faster construction means less energy used overall

All that adds up to one thing:

🌍 Lower carbon. Higher impact.

With BuildUp, sustainability isn’t a bonus - it’s built in.

Building block, but make it 2025.

It’s like grown-up LEGO. But instead of stepping on it, you live in it.

Right now, our lightweight steel frames from BeSteel Light steel framing are being used on the Senne Urbaine project, built by Meccabuild - and we couldn’t be more excited.

🧩 Precision-made

🧩 Quick to assemble

🧩 Strong enough for complex buildings

It’s construction with the mindset of manufacturing.

No mess. No delays. Just smart parts, delivered on time and locked into place.

Stay tuned - there’s a lot more to come on this project. 👀

Grown-up building blocks? Kind of.

Game-changing? Absolutely.

🧠 This is what innovation looks like. Spoiler: it’s not robots (yet). It’s people.

The BuildUp team isn’t just building walls and frameworks — we’re building the future of construction.

One project design, coffee break, brainstorm, and prefab panel at a time.

We’re engineers, coordinators, planners, doers, dreamers — and occasional snack sharers. 😄

Different roles. One mission: make construction smarter, faster, and better for everyone.

Because real innovation?

It starts with a good team and a bold idea.
