Our Hjalmar garden office is an airy and modern home studio covering approximately 13 m². The large glass sections that run over almost two entire walls make the interior feel spacious and light. The office design offers plenty of space for office furniture and other interior details that enhance the work environment. Work amongst your thriving plants!

Hjalmar is a strong, notch-timbered structure, but with hidden notches. This gives the garden office a stylish, clean look and helps it to blend into most environments. You can build the flexible kit in just a couple of days!

How easy is it to assemble?

You really don't need to be a carpenter to build the home office, you can do it yourself with the help of a friend and our manual. Once you have prepared the foundation, you can begin to build the garden office. The timber wall sections are connected to each other according to the illustrations in the manual and the building grows step by step.

Our offices are developed by our own experienced designers. If you have any questions about the product or assembly, you are always welcome to contact us, and we will help you.
