We wanted a hallway unit to store coats, bags, gloves, hats and all the items we normally lose between seasons. IKEA item used: KALLAX 5×5 UnitKALLAX 4×2 UnitDRÖNA Box x 22 x KALLAX Door Insert2 x KALLAX Shelf insert5 x KARTOTEK Hooks Other materials and tools: 3.6mm single faced ply Oak veneer sheet cut to size (1820mm x 770mm)4”x1” timber 770mm longSome screws Hallway unit instructions Using the ‘inside’ length from the 5×5 KALLAX and the outside smaller “2” end from the 4×2 KALLAX, we created the initial L shape. Related: KALLAX for mudroom and entryway organization cubbies Using the provided dowels, add a top and bottom shelf and divider from the 4×2 set. This will give you 2 boxes, a gap of 3, then 2 boxes. Once finished, cut down the protruding dowels. Since this is not structurally sound, screw the 3.6mm veneer ply to the back (Woodshop Direct’s Crown Cut Oak is a great match for IKEA’s White Stained Oak effect) Once this is done, add the KALLAX doors to the top and the KALLAX shelves to the bottom. We put the DRÖNA boxes on top to store out of season items. Screw the 4”x1” timber to the back and screw the KARTOTEK hooks into the timber. (You could of course use any hooks you prefer!) Add a cushion for comfort. (You’ll also have enough KALLAX left over for a 5 x 4 Unit) How long and how much did it cost? KALLAX 5×5 = £150KALLAX 4×2 = £55KARTOTEK 5 Hooks = £10Veneered ply = £412 x Doors = £18Shelf inserts (2) = £182 x DRÖNA = £6 Total = £300 (But you also get a 5×4 KALLAX Unit!) What do you like most about the hack? It’s in keeping with our house and other IKEA furniture. And you can make it wider if you want by getting a 4×3 KALLAX and larger ply board.

What was the hardest part about this hack? Taking the risk the ply would match the IKEA unit … and it did! What to pay special attention to? Woodshop direct, cut-to-size and delivered! Best to anchor it the entire unit to the wall too. ~ by Tony B.
