Bjørn wanted to make a long workstation which has room for two at the same time and has numerous drawers/cabinets where you can hide all office supplies. This is an IKEA hack that is incredibly easy to make and you can even choose if you want lots of drawers or cabinets. You can also make it for one person also by cutting the worktop and adding two cabinets instead of three. See the dual computer workstation.
#3 Wall unit with computer desk and shelving
Rhiannon made a custom designed wall unit, with a computer desk and plenty of shelves for books. Her hack uses the old EXPEDIT but this can be easily replicated with the KALLAX shelving unit. See more the wall unit with computer table.
