Home & Garden - Various Applications

The Beamlock System was created in Switzerland as a result of 25 years research and development by a prominent expert in the field of design technology...

Great care has been taken to retain the appearance and craftsmanship associated with traditional mortise and tenon construction and as a result an improved level of quality and value for money has been achieved. We hope that this investment into design will give you a pleasant result, both in terms of authenticity, ease of assembly and value.


The system is ultimately flexible and we can use it to create most simple one-storey buildings. Examples are below.
