Ikea's modular "Kallax" shelving units [1] are famous for their flexibility. From using the largest sets as room dividers or bookcases to repurposing the smaller ones as coffee tables or hallway cabinets, there is a use for Kallax in just about every room of the house, and given how affordable the shelves are, you'd be a fool not to work them into your next home refresh. These real home designs show just a few of the creative ways you can use the cube-shaped shelving in fun ways, from creating low bench seating to using the cubes to house fish tanks (no, really) — there is no end to the ways people have customised and hacked their Kallax to suit their homes. If you're not so handy at DIY [2], even the smallest touches can set your look apart: try varying the boxes and drawers you put inside, or switching out the handles for something more customised.
