Cardboard wall is surprisingly well built

We all built cardboard forts when we were kids. [Paintingcook] has taken it into adulthood with a hand built cardboard wall. He and his wife leased a loft apartment. Lofts are great — one giant space to work with. Plans changed a bit when they found out they had a baby on the way. A single living, working, and sleeping space definitely wouldn’t be good for a newborn, so the couple set about separating a section of the room with a wall.

Sheetrock and steel or wood lumber would be the normal path here. They instead decided to recycle their cardboard moving boxes into a wall. The boxes were formed into box beams, which created the framework of the wall. The two pillars were boxed in and incorporated into the wall itself. The skin of the wall is a random patchwork of cardboard pieces. Most of the construction is completed with 3/8 ” screws and masking tape. Tape won’t last forever, but this is a temporary wall after all.

You might be wondering about fire hazards — sure, cardboard burns more readily than gypsum board, but the apartment is outfitted with sprinklers, which should help on this front. A few commenters on [Paintingcook’s] Reddit thread asked about formaldehyde and other gasses emitting from the cardboard. Turns out he’s an inorganic chemist by trade. He says any outgassing happens shortly after the cardboard is manufactured. It should be safe for the baby.

Cardboard is a great material to work in. You can build anything from robots to computers to guns with it. So get hop the couch, grab that Amazon box, and get hacking!
