End of November 2011, the contractor finished with my attic. The interior finish would be my cup of tea.
Between the work of the contractor I have in one weekend the electricity installed. If electrical engineer is the least you can try.
The list of what I had to do:

1. the iron fencing. My local construction company had welled it for me.
2. leveling up the floor so high that the mounting bolts of the fence in the floor were no longer visible.
3. seam sealants and paint walls, then the sockets / switches installed.
4. to make the high sleeper and the frame of the fence of hard maple. This is the same type of wood as my staircase.
5. desktop of birch plywood with laminate
6. to finish with white perplexed plates of the fence and stairwell. A plane in the fence is transparent
   plexiglass finished so there is a look to kitchen and thence to the outdoors through the sliding doors.
7. laying a beige linoleum floor with crocodile print
8. window frames with white laminate finish
9. stairs bunk and plexiglass handrail assembly to the overall finish.
   For Christmas I had finished my work. One difficulty was to make the view of the high sleeper so
   that no fasteners such as screws / bolts on the wide maple plank were seen.
