My second choice of space is 14m long x 2.4m high, I have drawn in the space what I think my figure can see.

Not only does the length of this room give you more options to add furniture and fixtures which then creates an atmosphere, it allows you to be more expressive and creative with colour and texture. The differences in feelings between the two spaces definitely have a lot to do with the size of the wall, it is possible to create a great atmosphere in a small space but there are limits, whereas with the larger space you can be a lot more adventurous.
