Your garden building is delivered as a simple self-assembly kit. All parts are
pre-fabricated and can be assembled relatively simply and quickly. Only a
few tools will be needed for the assembly – these tools are not part of the
delivered package. We recommend that at least two people work together
for the assembly. Please bear in mind: check before the purchase of our
product, whether a building permit is required.
If you need help assembling your garden buliding you can access the general
assembly instructions from here at any moment.

You can also see an online video that shows the assembly.
