Great design From:Tiny Houses Desk and shelf units - They are attached to the walls with 45mm x 35mm blocks which I have screwed straight into the studs. I then screwed through the back of the desk/shelves with long wood screws into the blocks. The big washers you can see on the desk units are needed so that the small heads of the screws dont pull through the wood, the weight of the fold out parts for the desk is supported only by the hinges.
The Podpad is a wall-mounted desk and storage unit that folds open for use as a workspace & holds your laptop, mail & desk junk plus it also houses a built-in sound system & charging station…. Doesn't look like it holds a printer though.
