Thanks for the feedback and ideas peeps.
With the kitchen (Daz do you have a link to the one we were talking about?), although i do agree to a certain extent that it does make good places to put stuff in, I just don't like the look. It doesn't look "workshop" like to me. I also not sure what work surfaces I would actually need tbh. Also the type of kitchen I would want for the garage (piano black or shiny cupboards etc) would cost me £££££.
Ultimately due to my work situation I need to keep costs down! I invested a lot of money just doing the up the garage with electrics, lighting, paint and buying shed, around £1500....
Dave - pictures on the same page mate. I think there was a subtle change in the contrast between the greys but I am not sure. I think the blue would look really good nevertheless.
