Boris_Crack, your map looks indeed very promising. I like it. but what do you mean by "limited props" ? there are hundreds of good props you can use for your office...books, pencils, document files, trash cans, tables, cables, electric switches, sprinklers...look at maps like archives or casino. you can use every single prop that you see there. choose a prop from the (goldeneye source) list, add the right class and then it's ready for your map.
and don't forget to use some decals, like (exit) signs, arrows, carpets. these things add more atmosphere to your map.
