The simplest thing to say, is that I just love the way it looks with all its texture and randomness. I also like the idea that it is both natural and man made; and that fact is very visible when you look at it. You can see the wood grain and yet, they're not quite right because they're all chopped up.
Mostly when you see OSB used in interiors, it's left bare, but I've seen examples where it is painted in a satin black and it can change an industrial material into something more luxurious. The idea of using inexpensive materials in interesting ways and making the design add more value than the cost of materials is something that has appealed to me since my final year Transport Design degree project (and is also the reason I love 'The House That £100k Built" TV show!)
The versatility of OSB as a building material makes it perfect for exploring in this way, and is why I used it in all my projects in The Great Interior Design Challenge. I hoped to be able to show the possibilities of using one inexpensive material in different ways and finishes; maybe help people think a little more about what can be done with a little creativity. Unfortunately, I ended up with 3 bedrooms out of the 5 rooms... and all wanted large statement headboards, so I didn't show much variety!
Having said that, with the exception of the Bristol bedroom, I don't think the OSB shouted in your face when you entered the rooms; its use was mostly subtle and could easily have been missed unless told beforehand. In that respect, I think I achieved what I wanted to, but I could have done more, and in the future I hope to experiment a lot more with this wonderful material!
