Our history
In 1978, after 16 years of professional experience, Hans Kälin founded the carpenter’s workshop of the same name as a “one-man business”. The field of activity was mainly the furniture and interior design.
In 1979 the first apprentices are trained in the carpentry workshop.
1982 – 1990, in order to fill gaps in the labor market, the company builds several turnkey chalets in traditional stud construction.
In 1984, the workshop is expanded and newer machines are purchased.
In 1998, the first wooden element house is built, thus creating a new branch for the diverse offer.
In 2001, son Christian completes his training as a federally certified technician TS.
2002 there is fresh wind in the company; Christian takes over the business with the three employees
2005 Wood construction is booming! A joinery hall is built next to the gravel plant in Trachslau for the production of the prefabricated houses. The company already has 12 employees.
In 2006, the sole proprietorship becomes a stock corporation.
2011 Construction work starts on an extension next to the existing joinery hall at the gravel plant.
2012 At the beginning of 2012, the timber construction production including a modern joinery center is put into operation in the new building. In the course of the year, the extension work of the new building progresses steadily.
2013 At the beginning of the year, the offices are moved to the new building at Trachslauerstrasse 13. Shortly thereafter, the carpentry shop also moves into the former joinery hall (built in 2005). Now the whole company is united at one location under one roof. The company has almost 30 employees.
2013 The first carpenter successfully completes his apprenticeship at the company in the summer.
2014 The sustainability of timber construction has also become established in multi-storey buildings. For the first time, a 5-story residential building (base floor solid, 4 floors timber construction) is built.
2015 The “KHT Kafi” is opened on the first floor of the company building. The catering business is run independently of the KHT.
2018 To round off the range of services, a timber construction engineer is hired, who from now on actively supports the timber construction planners..
2019 A grown company also needs new structures. The management team is being expanded and now consists of Christian Kälin (still managing director and main partner) and the two long-time employees Urs Kaelin and Stefan Schoenbaechler (both partners).

2006 wird aus der Einzelfirma eine Aktiengesellschaft.
2011 Neben der bestehenden Abbundhalle beim Kieswerk starten die Bauarbeiten für einen Erweiterungsbau.
2012 Anfang 2012 wird die Holzbau-Produktion samt modernem Abbund-Center im neuen Gebäude in Betrieb genommen. Im Laufe des Jahres schreiten die Ausbauarbeiten des Neubaus stetig voran.
2013 Zum Jahresanfang werden die Büroräumlichkeiten ins neue Gebäude an der Trachslauerstrasse 13 verlegt. Kurz darauf erfolgt auch der Umzug der Schreinerei in die ehemalige Abbundhalle (erstellt 2005). Nun ist der gesamte Betrieb an einem Standort unter einem Dach vereint. Der Betrieb zählt nahezu 30 Mitarbeiter.
2013 Der erste Zimmermann schliesst im Sommer erfolgreich seine Berufslehre im Betrieb ab.
2014 Die Nachhaltigkeit des Holzbaus hat sich auch bei mehrgeschossigen Gebäuden etabliert. Erstmals wird ein 5-geschössiges Wohnhaus (Sockelgeschoss massiv, 4 Stockwerke Holzbau) erstellt.
2015 Im Erdgeschoss des Betriebsgebäudes wird das «KHT Kafi» eröffnet. Der Gastro-Betrieb wird unabhängig von der KHT geführt.
2018 Zur Abrundung des Angebots, wird ein Holzbauingenieur eingestellt, welcher von nun an die Holzbauplaner tatkräftig unterstützt.
2019 Ein gewachsenes Unternehmen bedarf auch neuen Strukturen. Die Geschäftsleitung wird erweitert und besteht neu aus Christian Kälin (weiterhin als Geschäftsführer und Hauptteilhaber) und den beiden langjährigen Mitarbeitern Urs Kälin und Stefan Schönbächler (beides Teilhaber).
