Add-on module 'Half Strong' with door

From the makers of the Hochstapler shelving system there is a brand new system that I would like to introduce here with a drum roll: The 'Halbstark', quasi the little brother of the 'Hochstapler'.

And because the two are brothers, they also fit together perfectly: The two shelf systems can be perfectly combined with each other due to their identical design. The design possibilities are now almost limitless.

With this add-on module, you can extend the height or width of your shelf. It comes with a door, behind which all sorts of things can be stored. Just tell me whether you want the door to be hinged on the right or left, and whether 'Halbstark' should be white or anthracite.
