Sleeping lofts are a great way to maximise space. I really like this cabin with it's one legged ladder but I don't know that I think much of that 'safety rail'. Do you like it? Not the rail, silly - the cabin and sleeping loft!
The sun faded wood provides an infinitely rich space. The use of warm lighting offsets the grey cool-tones to give a dynamic inviting appearance that would be otherwise impossible.
