Thessa e-mail me and asked if I could show how we built the orange wardrobe and how the sliding door are hung. Sure, no problem!
The shelving system inside is simply one similar to the Elfa system. It's mounted to the back wall and the sliding doors are separate, they hang from the ceiling on a track that you buy at a specialty hardware store. We got ours from a local store called Theofils Beslag. Our wardrobe spans an entire wall so we measured the wall and asked the Theofils to cut the track to that lenght. We chose three doors for our 2.4 meter / 8 ft wall. Each door is 84 cm/33" wide so they overlap slightly when closed.
For each door you need to get 2 pcs of special hardware that is sunk and screwn into the back of the board you are using. We used 18mm /3/4" MDF for ours. The hardware is really simple to install as long you have the right size drill bit. At the top of the hardware are the little wheels that roll on the track (not visible in this shot).
This is what the track looks like from below. On the right track you can spot a metal thing infront of the oblong thing. That's a stoppers it prevents the door from opening itself up if you have a somewhat sloping ceiling as we do.
Hanging the doors is so easy once you have installed the track. The installation of the track is simply a matter of using the correct screws and plugs for your ceiling, your hardware store can help you there. When the track is up and the doors have the hardware on you just pop the wheels onto the tracks and let them hang down. MDF is pretty heavy in these sizes but if you use the right track for the weight of your boards you'll be fine. Along with the hardware came some little floor track bits, just little penny sized 15 mm /1/2" tall things that you can sink into your floor to prevent the doors from swaying in and out. We didn't want to drill into our floors so our doors just hang freely.
We added a piece of wood in front of the track so it's not visible from the front. The height of the track is 4.5 cm / 1 3/4" and the wood we used is 8 cm / 3 1/4" which also hides the hardware which would otherwise be seen from the front above the MDF. This piece of wood was screwn into the ceiling too.
The wardrobe doors have been up a couple of years and we've had no problems whatsoever besides from the fact that I'm bored with the orange trellis pattern and will put wallpaper on them soon. If you on the other hand like the trellis pattern you can find a painting tutorial here.
