Take one picture of the space. Phone camera is fine. The wonky angles, the radiator, the molding, all of it helps us see what you see.
Photograph a corner. Tell us your vision. We send back every piece cut, sanded, and finished, ready to live in without a single power tool.
Materials prepared in Europe and the USA · No power tools needed · Ships in 14 days


The wall isn't square. The radiator's in the way. IKEA's closest size is five centimeters off, and a carpenter wants four thousand euros and six weeks. So the corner stays awkward, the shoes stay on the floor, and you promise yourself you'll figure it out next year.
We built knuslabs to figure it out for you.
No CAD software. No back-and-forth with carpenters. No power tools at the end.

Three numbers: width, height, depth. Use a tape measure or your phone's LiDAR. We work with whatever you've got.
"Built-in bookshelf with a reading nook." "Bench seat for the entryway." Plain English, as specific or vague as you like.
In minutes, knuslabs generates four custom designs that fit your exact space, in your exact style. Walnut, oak, painted MDF, you choose.
Tweak the dimensions, swap the wood, try a different layout. When it feels right, you confirm. We send a final render and the price.
Materials arrive cut, sanded, and finished. Pre-drilled. Numbered. The whole thing snaps together with the included Allen key in an afternoon.
Each option is dimensioned to your wall, costed to the cent, and ready to confirm. No CAD. No phone tag. No waiting.

"Built-in bookshelf with a reading nook tucked into the corner. Low and warm, oak feel, room for art books and a small lamp. Cat needs to fit on the bench."
[Drop in a real customer render here. Per Ruud: "use an actual example for that".]
No estimating sheet goods. No standing in the lumber yard. No pile of off-cuts in the corner. The moment you confirm an option, knuslabs orders the exact material in the exact quantity, cut to the millimeter your wall actually has.
I moved into a 38 square meter apartment in Amsterdam in 2023. The kind with a slanted ceiling, a brick chimney where you don't expect one, and walls that wave a little when you run a level along them.
I wanted a built-in. Bookshelf, bench, somewhere the cat could sit and judge me. IKEA's nearest size was eleven centimeters off in one direction. The local carpenter quoted forty-five hundred euros and a six-week wait.
So I learned to read CAD files, drove to a wholesaler with a borrowed van, and three weekends later I had something that fit. Six hundred euros in materials. The whole way through I kept thinking: if a tool could do the design and the cut list for me, this would be a Saturday afternoon.
“knuslabs is that tool.”
