Astrain AG was founded in October 2023 by Bruno Hehli and Edmund Inauen. In January 2024, we were able to take over the renowned timber construction company Ulmann Holzbau AG, where we had previously gained extensive experience. Thanks to our extensive knowledge of operational processes and modern infrastructure, we are able to implement projects efficiently and to the highest quality. Our customers also benefit from a well-coordinated team that can draw on many years of expertise in timber construction.

Timber construction:
Timber not only connects us as a structural element, but also our team. From the very beginning, the history of astrain has been closely linked to the sustainable raw material wood.

We are proud to work with wood and understand our craft - always striving to achieve the highest precision, variety and creativity.

Interior fit-out:
In the field of timber construction, interior fit-out is also one of our core competencies. We enjoy the versatility of wood as a material and design staircase constructions that not only connect floors, but also perfectly combine function and aesthetics.
