Building extension
Uncomplicated with wood

Building extensions
made of DERIX wood

Especially in urban areas, living space is becoming scarce. Since there are few open spaces here that are suitable for new development, it makes sense to increase the density of existing buildings by adding more storeys, thus creating additional living space. However, additions of storeys also bring challenges, as the static conditions have to be taken into account. A low weight and a high degree of prefabrication of the built-up constructions is of central importance here. For these requirements, the construction method with DERIX solid wood elements offers the optimal solution.

Why build extensions
with DERIX wood?

In addition to their low dead weight and high degree of prefabrication, our solid wood elements bring other significant advantages for building extensions. Learn about the numerous positive effects of timber construction.

Light and flexible
building material

When adding storeys to a building, lightweight constructions must be used above all so as not to put too much strain on the statics of the existing building. This requirement is fully met by our solid wood elements: They have an enormous load-bearing capacity with a low dead weight and can be designed accordingly narrow.

High degree
of prefabrication

Element construction and modular construction are suitable for building extensions. Both construction methods are characterised by a very high degree of prefabrication. You benefit from this especially during assembly: the cramped spatial conditions that are usually encountered with an extension are much less of a problem with timber construction than with conventional construction methods, as the prefabricated timber elements can be assembled very quickly.

High quality and aesthetics

A building extension in solid wood construction enables the realisation of countless architectural designs. Even creative ideas can be implemented with high quality using the flexible natural material.

indoor climate

Thanks to its positive properties, wood as a natural building material ensures a healthy indoor climate in added living spaces.


By adding a building with DERIX solid wood elements, the buildings become ecological and potentially circular real estate. The environment also benefits from timber construction.


By adding wood to your building, you are flexible in the design and can plan your building individually. This will make your raised building unique and stand out from the crowd.


X-LAM element construction

Whether roof, ceiling or wall – X-LAM can be used in a variety of ways. Our X-LAM element construction gives you great freedom in building design. The flexibly usable elements made of cross laminated timber are custom-made for you and can be assembled quickly and easily.

Wooden module construction

The timber modular construction method makes fast and sustainable building possible. We prefabricate three-dimensional wooden room cells in the factory, which are then assembled on site. From planning to production to the turnkey building – get to know DERIX modular construction.

Sustainable building with wood

Wood is a renewable and natural raw material that stores CO2 and thus relieves the environment. Wood is a renewable and natural raw material that stores CO2 and thus relieves the environment. Learn more about the topic of sustainability when building with wood.
