I found out from surfing on the Internet that doubling the KALLAX 2×2 shelving unit would support my aquarium. So I have bought and installed them by each other to make a wide piece of furniture able to support the weight.
Fish tank stand and room separator – after:
To better visualise the room separation even better, I screwed on at the back of the KALLAX units painted MDF and wood slats. And then behind, screwed some thin and painted MDF panels (1200mm x 6mm) at 4cm from the ground in order to be able to hide the aquarium’s wiring system and create a more visual separation from the sofa side.
Jeanie attached 4 STUVA storage cabinets together and then added plywood and plaster to the back to make a free-standing room divider. Besides dividing the space, it offers plenty of storage. See the hack.
Midcentury-style room divider and desk
Laurence used STOLMEN poles (discontinued, replaced by the ELVARLI system) to create a stunning bookshelf and desk space. It also effectively divides the sitting room and bedroom. Take a look at the hack here.
