69teile / stairs


Puzzle your own stairs!

You need a perfectly fitting, flush mounded, easy to install wooden stair? No matter how tiny your available room is, just give me the details of your location. You will get from me a innovative product, which comes in a compact parcel directly to your front door. Now you can start puzzeling the CNC milled wooden pices. After mounting it with just a few screws onto the wall you will have built in almost no time and with a lot of fun a fully fledged wooden stair.
