A Closer look at the Expandable Trailer

The Baubuch explained

A Baubuch brings together all relevant technical information of an Expandable Movable Space in one clear document. It typically includes drawings, structural and load calculations, parts lists, certificates and supplier information. Together, these elements show how a space is built and why specific technical choices have been made.

The Baubuch is created during the project and grows as the design becomes more detailed. This supports consistent collaboration between engineering, production and external stakeholders, while reducing the risk of missing or unclear information in complex or customised projects. Beyond delivery, it remains a practical reference for maintenance, adjustments and repeat builds, ensuring that essential information remains accessible over time.

When new or bespoke solutions are developed, the Baubuch evolves alongside the engineering process. It documents not only what is built, but also how and why decisions are made. Depending on market requirements or documentation needs, customers may choose to include a Baubuch as an optional part of the project, resulting in a complete and traceable technical file for approval and future reference.

Importance of the Baubuch

In regulated markets, a complete and approved Baubuch is often required before an Expandable Movable Space can be inspected and delivered. Inspection authorities such as TÜV use the Baubuch to verify compliance with applicable technical and legal requirements. For customers, it reduces uncertainty by clearly documenting approved solutions and the assumptions on which the design is based.

Without this documentation, inspections often lead to additional questions that can cause delays or late-stage changes. Across Europe and the UK, requirements vary between authorities and locations, which can lead to discussion or misalignment when documentation is incomplete. In these cases, the Baubuch helps structure the approval process and supports clear communication with external parties.

The value of a Baubuch becomes especially clear when Expandable Movable Spaces are used across different markets and applications. In the DACH region, technical documentation is typically reviewed in detail before approval is granted. Clear insight into structural behaviour, fire classification and material choices helps prevent follow-up inspections and additional clarification requests.

In the UK and Ireland, Expandable spaces are often assessed as temporary structures for events, exhibitions and brand activations. Local councils, event safety officers and venue operators rely on technical documentation to support their risk assessments. The Baubuch provides clarity on construction principles, installation methods and intended use, supporting consistent evaluations across multiple locations.

For international event deployments, such as touring activations or trade fairs, the Baubuch serves as a shared reference for organisers, safety consultants and logistics partners. It helps align expectations before installation and reduces on-site discussion. Beyond events, the Baubuch is also relevant for semi-permanent installations in public or commercial environments, where municipalities or property owners may request documentation that clarifies long-term use, maintenance and permitted modifications.

Key benefits

The MTC is designed as a true plug-and-train solution. It is fully operational within 30 minutes of arrival. Our patented Touchdown technology retracts the wheels to the rear of the chassis, lowering the trailer close to ground level for a low entry height, easy access, and improved stability. The platform combines immersive features such as the LED wall, sound floor, and reactive covers with Guardiaris’ advanced simulation content. Training scales easily from individual drills to squad-level scenarios, with real-time performance metrics and customizable layouts. Mobile, cost-efficient, and user-friendly, the MTC lowers total cost of ownership compared to fixed facilities, while being faster to deliver and easier to deploy.

Two experts, one solution

We founded Expandable to deliver something the market lacked: movable spaces that are easy to operate, affordable, and fast to deliver. This vision led to our patented Touchdown trailer, designed to maximize accessibility, stability, and ease of setup.

Guardiaris brings nearly two decades of expertise in simulated training. Their GUARD simulation engine and patented LED solutions create training environments that are realistic, repeatable, and measurable — from small-arms marksmanship to complex tactical missions.

‍

“With the MTC, we bring the capability of a permanent training facility to any location, with the speed, accessibility, and flexibility modern defense forces demand.”

— Richard Vlegels, Head of Business Development & Sales – Defence and Security, Expandable

“Integrating our GUARD simulation engine inside the Expandable Touchdown platform creates a reliable plug-and-train environment — realistic, measurable, and ready to use on arrival.”

— Kim Sevšek, Business Development Manager, Guardiaris

Availability & customization

The MTC is available for defense, law enforcement, and security organizations. Configurations can include additional scenario modules, instructor stations, data logging, and ergonomic options. Branding and interior layouts can be fully customized — while maintaining short delivery times.

The foundation of this solution is a heavy-duty 6x6 truck built to handle rough and remote terrain. On top of it sits a compact Expandable Pod that expands on location into a spacious living area. Inside, there are fixed bunk beds for six team members, each with its own reading light, power outlet, and small storage compartments — small features that make a big difference in tough conditions.

The layout is simple and practical. The kitchen includes an induction cooktop, fridge, sink, and ample storage. A dining area provides seating for shared meals or team meetings. There's also a small lounge space with windows, offering a bit of normalcy and relief during downtime. The pod includes a separate shower room and a toilet, and even a washer-dryer combo to handle laundry independently — no need for external facilities.

To stay fully self-reliant, the pod is equipped with both a generator and a battery system. This setup enables true off-grid living without relying on external power sources. Heating and air conditioning systems keep the interior comfortable in any climate, whether in desert heat or cold mountain air.

One standout feature is the rooftop terrace. Accessible via a built-in ladder, it adds extra functional space — whether for relaxing, overseeing the camp, drying gear, or just taking a quiet moment away from the ground-level hustle.

What sets this build apart is how precisely it matches real-world needs. Every element inside serves a purpose. Everything is where it needs to be. There’s no unnecessary luxury — just a compact, comfortable, and functional space that supports the rhythm of a rally team on the move.

For Shiver Offroad, the biggest win is mobility. Everything travels with the team. Everything is always within reach. No hassle with temporary tents or booking accommodations. Just pull up, expand, and get to work — or rest.

In a sport where every second and every detail counts, having a stable, reliable basecamp is a serious advantage. This mobile unit proves that with the right layout and design, even in the most remote places, you can still have a place to call home.

Real-world challenges demand real testing

‍
The flexibility and mobility of expandable spaces make them an attractive solution across various industries. From temporary offices and mobile homes to portable healthcare units and classrooms, these units are built to move. But with mobility comes the challenge of performance under diverse conditions. Customers rely on these units in different environments – whether it's a construction site, a disaster relief zone, or a rural community. The expectations are high, and failure isn’t an option.

That’s why we don’t leave anything to chance. Our testing process involves replicating the types of stresses and strains these units could face on the road and in use. Our testing isn’t limited to just static conditions. We test our units while they’re in motion, subjected to heavy loads, and on complex terrains.

One such example is testing on banked test tracks, where our units, mounted on trailers, are driven at angles far steeper than any real-world situation they might encounter. By simulating the forces of turning, braking, and accelerating under various loads, we can ensure that our expandable units maintain their structural integrity, no matter the road ahead.

Testing for different weight classes

‍
One of the standout features of Expandable's relocatable spaces is their adaptability. Customers have varying needs, which means that the load a unit might carry can vary significantly. Whether it's a lightweight mobile office or a heavily outfitted disaster response unit, we design our products to handle a wide range of weights.

To ensure they perform under all conditions, we test our units with different weight configurations. Our lightweight tests involve simulating scenarios where the unit is minimally outfitted, while our heavier tests replicate a fully loaded unit, accounting for additional equipment and supplies that may be transported inside.

During these tests, we measure key performance indicators such as structural stability, balance, and the unit's ability to withstand external forces like wind resistance and road vibrations. These tests ensure that no matter how our customers plan to use their expandable space, the unit will perform reliably and safely.

Pushing the limits of adaptability

‍
One of the key selling points of Expandable’s products is adaptability. The ability to transport these units easily and set them up in different environments is crucial for our customers. But adaptability isn’t just about ease of use; it’s about ensuring that these units perform consistently, even when they’re pushed beyond normal use cases. Our team continuously refines the design based on these tests to make sure that every Expandable unit delivers reliable performance, whether it’s being set up in the desert or in a freezing mountain range.

Safety as a top priority

‍
Durability and adaptability are crucial, but safety is non-negotiable. For Expandable, safety isn’t just about meeting minimum industry standards—it’s about going above and beyond. Our testing protocol ensures that not only do our products survive tough conditions, but they also keep users safe in the process.

During each phase of testing, we evaluate the impact of stresses on structural components and materials. We want to make sure that our units remain secure, even when they face sudden shifts in terrain, temperature changes, or heavy impact. We also test the units for ease of evacuation and access during emergencies, ensuring that our clients can rely on these units even during the most critical moments.

Why extreme testing matters?

‍
In the end, our rigorous testing processes are what set Expandable apart. We’re not just building relocatable spaces; we’re building trust with our customers. When a client chooses one of our products, they need to know that it will perform without fail—whether it’s during a major storm, in rough terrain, or after years of use.

This confidence comes from knowing that each Expandable space is thoroughly tested to withstand both everyday wear and tear as well as the une

The Genesis of Expandable

Expandable was founded because our owner Michiel Becx wanted something that wasn’t available on the market – a movable space that is easy to operate, affordable, and with a short lead time. Needless to say, he succeeded at that. The motivation to found Expandable has been the driving force of our company ever since. To be specific, the desire to keep reinventing ourselves to stay ahead of the market, and keep filling in the gaps between what the market has to offer and what the customers want.

Our latest product line, highlighted by the Expandable Touchdown, is the poster child of this mentality. But in order to prevent others from running away with this technology, we had to act. In this newquest, we partnered with Patentwerk to secure the patent needed to stay in control.

Ingenious technology

Thanks to an ingenious technique, the wheels roll out from under it, after which the Expandable lowers almost to the ground. The low step makes the space easily accessible and more attractive. Previously, the wheels either retracted into the unit (Hybrid Trailer), remained under it (Trailer), or were connected to a separate vehicle (Container).

However, there never was a patent, and with all the time and work we put into the design, it would be a real shame if a competitor ran away with it. But this time, we decided to grab the bull by the horns and work together with, in this case, Saskia Schildkamp of Patentwerk. “Our main task is to describe the crux of the invention”, she says. “If the description is too broad, you risk the patent not being granted. If the description is too specific, the competitor can easily work around the patent.”

Securing innovation

Having a strategic partner in the patent application process, we were able to keep focusing on production and development, safe in the knowledge that a technically and legally correct patent application was being made. Not to mention time being spent needlessly on something outside our field of expertise.

“We submit the patent application to the Dutch Patent Office, which is authorized to issue the final patent”, continues Schildkamp. “For obtaining patent protection internationally, we take a different route. Patent granting procedures can take several years. It is important to start before the product is on the market and possibly even before there is a prototype. In the meantime, the company can continue development.”

Dotting the i’s, crossing the t’s

This two-way collaboration resulted in the successful development of a unique product alongside a decisive patent application process that is still continuing. “We are now in the process of having patent protection for the invention applied internationally”, continues Berrie. “Once a savvy person knows how it works, it is relatively easy to recreate. That's precisely when a patent is advisable; it helps you keep a grip on your invention. This patent is yet another step that will help us become even more of an option in today’s industry.”

Set-up: 1 person, 15 minutes

You don't need to be a techie to operate and set up an Expandable. The user-friendly hydraulic system is easy to use with wireless remote control. The result? In just 15 minutes, anyone can set up an Expandable. In the blink of an eye, the floor area of an Expandable doubles.

What our customers say

"Our business is all about trust. We know we can trust Expandable", says Serge Blommaert of Xtreme Concepts, a roadshow organizer. "They will always play an important role for us." He knows what a good roadshow needs, and what it is that Expandable provides to make that happen.

"I see Expandable as a partner, not a supplier", says Marsden Proctor, CEO at Facilities by ADF, one of UK's largest partners for tv and film productions. Not necessarily working in the roadshow business, Proctor is very familiar with the importance of being mobile, movable, and adaptable. "Expandable delivers high-quality products", he continues. "That allows us to set the bar high in our field."

However, Theo van Essen of Van Essen Catering & Events is familiar with the roadshow side of things: receiving guests and catering to their needs. "When guests walk in, they are immediately amazed at how nice and smooth the Expandable is," says Van Essen. "It's nice and warm inside, and well-lit, too – much better than a flapping tent."

And if you really want to go out of your way to make something memorable, take a page out of the book of Wim Noorman, head of Eurotech Sports & Events: "I am always looking for innovation – how to do something faster, smarter, cheaper, better. Eurotech and Expandable share a common goal; to deliver a unique and optimal experience."

Meet the Expandable Pod

With Expandable, meticulously furnished rooms are no longer bound to their location just because they happen to be between four concrete walls. Take your experience on the road and do what you always do, not restricted by location. Visit fairs and exhibitions with the confidence that your company can be the best version it can be.

What makes the pod different from other models is that it isn’t bound to a specific vehicle. It can be put on any normal truck, secured with four twist locks and lashing straps. Don’t let its compactness fool you though – that dissipates as soon as the pod is fully expanded. The Expandable Pod comes in three sizes: 25 feet (7,6 meters), 30 feet (9,1 meters), and 44 feet (13,4 meters). When fully expanded, the number of square meters more than doubles. Within a mere 15 minutes, the Expandable Pod turns from cargo load into a full-fledged room. Truly, this is the definition of movable spaces.

How to set up the Expandable Pod

You might wonder how a Expandable Pod goes from a semi-trailer to a stationary position on the ground – and back. No, you don’t need a crane. All you need to do is follow this six-step procedure to set up the Expandable pod. You don’t need anything else: just your trailer, the Expandable Pod, and one human being to control the process. Let’s jump in!

• Step 1: park your truck at a secure location. A level surface is nice but not necessary (more on that later).
• Step 2: lower and slightly expand the Expandable Pod so its hydraulic legs can lower to the ground, raising it completely off of its wheels.
• Step 3: when the Expandable Pod is completely free, you can safely drive the truck out from under it.
• Step 4: now you can fully lower the Expandable Pod to the ground.
• Step 5: push the button for auto-leveling and the Expandable Pod will be leveled horizontally.
• Step 6: fully expand the left side of the Expandable Pod, simultaneously lowering the left side part of the floor. Repeat for the right side.

How about you?

Each Expandable Pod is just a glass wall with two sliding doors away from an attractive and representative exhibition room. Being fully customizable, Expandable Pod is not limited by options but just by the boundaries of your imagination. We offer the tools – it’s up to you how you use them.

The Expandable Touchdown is as flexible and easy to transport as any trailer, yet it retains a low step-in height and compactness. Today, we take a closer look at the Expandable Touchdown – a new era in mobile technology.

Meet the Expandable Touchdown

The Expandable Touchdown ushers in a new era in movable spaces. because it managed to solve a crucial question. How can a mobile unit fully lower to the ground (thereby creating a low step-in for visitors) without compromising on interior space? Using new and patented technology, the Expandable Touchdown is the first of its class that manages to do both without compromising on either. It truly is a unique player on the market. And it's still easy to set up as well!

How can the Touchdown have wheels, yet still have a height of only 35 centimeters off the ground? That is because of a little feature called the axle box. This is where the wheels disappear into as the hybrid lowers to the ground. From the inside, it looks like a metal box that can be used for various purposes – a bar, a table, or perhaps even a desk. It’s a feature, not a bug, that can be incorporated into the interior design of the hybrid trailer.

• Simple and quick setup, just 15 minutes for 1 person;
• A low and inviting entrance;
• A compact design, yet spacious when fully set up;
• Transportable by a normal or low-deck truck;
• Modular design with options to pick from like electric door(s), single/double hinged door(s), harmonica doors, glass side panels, roof terrace, air conditioning and heating.

How to set up the Expandable Touchdown

• Step 1: lower the front legs, raising the Expandable Touchdown so the truck can drive out from underneath it.
• Step 2: lower and slightly expand the Expandable Touchdown so its rear legs can lower to the ground, raising it completely off of its wheels. You can now manually raise the side skirts.
• Step 3: slide the rear axle bogie slides to the back, picking up the rear bumper and sliding further to the rear so the wheels fully retract to the back of the Expandable Touchdown.
• Step 4: with the wheels at the back, lower the Expandable Touchdown fully to the ground.
• Step 5: fully expand the left side of the Expandable Touchdown, which simultaneously lowers the left side part of the floor. Repeat for the right side.
• Step 6: draw the curtain over the rear bumper to cover the rear axle bogie, and attach the stairs to the Expandable Touchdown.

How about you?

The Expandable Touchdown is a versatile and efficient trailer that can help you expand the capabilities of your company. Its design, versatility, ease of use, and durability make it an excellent choice for a variety of applications.
