Modular construction

Modular construction is a process in which elements are produced in a controlled environment and then assembled on-site easily and quickly to form permanent, sustainable buildings. We produce ready-to-use building products from our factory in Wognum, such as apartments, hotel rooms, and bathrooms. The construction system has been continuously developed and perfected over the past decades. We now have four unique construction systems and can build up to 23 construction layers in a modular way. These are standardised and adaptable to specific project assignments.

Once the design has been approved, a prototype can be built. This prototype is tested and approved by our client before proceeding to the production of the series. The modules produced, including the installations, façades and interiors, are tested on the production line before release. This allows us to guarantee a perfect product upon delivery.

When the modules arrive at the construction site, they are put in place by a crane, after which they are linked. The installations for water, sewerage, air and electricity are connected to the central pipes. The façade is are further finished, resulting in a seamless, high-end building.

The modules consist of a concrete modular floor with a supporting structure of wood, steel or concrete. The walls, façades and modular roof are made of ecological timber frame construction or Cross Laminated Timber (CLT).

The process is as follows: all elements are set up in BIM and designed digitally. This digital information is sent to the machinery for sawing the wooden parts and plates. The timber frame construction elements are produced fully automatically with CNC milling machines. In the second part of the factory, the module is assembled on the conveyor belt, starting with the concrete floor to which the supporting structure, walls and roof are mounted. After which, the finishing and installation are done. The residential modules are completely windproof and waterproof and are finished for transport.

Residential housing is composed of multiple modules up to 4 meters wide. Linking modules on location ensures that we can produce a vast number of housing types.

Modular construction has several advantages, in which time savings are a major factor. After all, construction largely takes place in a factory instead of a construction site so that the production of the modules can run parallel to the earthwork and foundation. Partly because of this, projects can be completed up to 50% faster than with traditional construction.

Modular construction projects are also less vulnerable to weather conditions and are not dependent on many subcontractors. In the factory, the production processes are energy efficient, and the waste production is less than 1%, while in traditional construction, it is 10-15%. Modular construction leads to fewer transport movements, which results in a reduction of noise, nitrogen, dust, traffic jams and CO2 emissions. Once arrived on site, the modules are already equipped with installations and interiors.

Modular construction also offers many advantages at the level of sustainability and circularity. For example, by building modularly, it is easier to achieve high BREEAM or LEED scores. Most modules can also be disassembled so that our client can respond to a continuously changing market, and the modules and elements can be reused for a sustainable future.
