Hunde Hus Indoor Dog House/Bedside Table. And while we think the pet retreat is very cool, it's that wall that wowed everyone. So we went right to the source. Here's what Mads said...
The wall is a "Scrap Wood Wall". It is made from various lengths of 2x4s ripped in thicknesses from 1/4 to 1 in. I put all the pieces through the thickness planer to get one smooth side and gave them a walnut stain. The pieces were then randomly attached to the wall with hot-melt glue.
