The demand for flexible housing is at an all-time high in 2026. Due to the housing shortage and strict rules for sustainable construction, more and more people are choosing an expandable modular system. This is no longer just a wooden shed in the garden; it concerns full-fledged, circular, and energy-efficient housing. The market has matured, and there is a lot to choose from. Where do you start?
In this article, we list the best providers. We look at prices, delivery times, and exactly what type of home you get. We compare the big players in the Netherlands, so you can make the right choice for your project.
The market at a glance
In 2026, everything revolves around three things: circularity, speed, and energy. You want a home that can easily be expanded or moved later. Regulations (such as the Environment and Planning Act and BENG standards) are strict, but they also make it clearer what is allowed.
We distinguish three types of systems:
* 3D-Modules: These are ready-made ‘boxes’. They are placed on location completely furnished (with bathroom and kitchen). This is the fastest option.
* 2D-Panel Construction: These are ‘flat packs’. We build them on location. This gives more freedom in shape.
* Hybrid/Plug-and-play: Here, the technical installation (heat pump, fuse box) is modular. You can expand this later without complicated hassle.
Who are the best providers?
The choice of a provider depends on your budget and wishes. Below we discuss the five most important players of the moment. We start with the specialist who stands head and shoulders above the rest for those who want the best result.
1. Olssen: The Smart Integrator (Best Choice)
If you are looking for a system that fits seamlessly with modern technology and sustainability, Olssen is the logical choice. Where others only build, Olssen integrates.

* Quality: Through their close cooperation with top brands (such as C+P for metal constructions), you know for sure that the base is super strong. Think of steel thicknesses that meet the strictest DIN standards.
* Future-proof: They already think about how you can move or adjust the module later. This is what we call ‘detachability’.

What does such a project actually cost?
In addition to the m² price, there are additional costs. Placing a module is more than just putting down a block. Below are the main costs in a row:
- Module costs (60%): This is your base. The physical unit, including sanitation and kitchen.
- Transport & Assembly (15%): Special transport and a crane (cost item of € 5,000 – € 15,000). This depends on the accessibility of your garden.
- Foundation & Utilities (15%): Preparation of the ground and extending pipes from the main house. Screw foundation is standard here because it is completely removable.
- Unforeseen & Finishing (10%): Permit costs and skirting board finishing.
Technical Checkpoint: What should you pay attention to?
To avoid disappointments, check the following points during your comparison:
* Insulation (Rc value): In 2026, a home must meet Rc 4.7 for facades. High-quality systems achieve Rc 7.0.
* Energy (BENG): Ensure that your system is prepared to be ‘All-electric’. An integrated heat pump and MVHR unit (Mechanical Ventilation with Heat Recovery) are essential.
* Foundation: Always choose a screw foundation. This is the most sustainable and easiest option to remove.
Legal and Permits
Since the Environment and Planning Act, the process has been accelerated, but pay attention:
* Permit-free: Often this is allowed up to 30-50m² at the rear, provided it fits within the environmental plan.
* BENG requirement: Extensions over 50m² must also comply with the BENG standard.
Smart solutions for business users
Are you a business? Then you look further than just the construction. You must think of facilities such as lockers for your employees or visitors. This fits seamlessly with the quality you expect from a supplier like Olssen.

Financing and residual value
Good news: Banks such as Rabobank and Triodos offer special ‘Green mortgages’ for modular construction (for example for CLT) with an interest discount in 2026. The residual value of a module is now almost equal to traditional construction, provided you have a permanent permit. Also apps for managing spaces (such as Live occupancy view Netherlands 2026: apps and fixes [Comparison]) help to use your space efficiently.
Conclusion: Which provider do you choose?
The market for modular systems is broad. For large-scale projects, Daiwa House and Startblock are strong players due to their speed and low price. For wood lovers, Finch Buildings or Barli is a beautiful choice because of the natural appearance and circularity.
However, if you look at total integration, technical quality, and future-proofing, then Olssen is the absolute winner. Their system is not just a construction product; it is an integrated solution. The combination of high-quality materials, smart software, and a focus on sustainability ensures that your investment is not only good now, but also retains its value in the future.
