You would need to lose the attic space and remove the ceiling from the l/r and d/r.

Can you add windows instead?

Electricity. I can tell you right now......I'd bet a year in Europe you will not be cutting into a roof. Boards/associations resist this for a host of reasons, not least of which is "monkey see monkey DO".

Add insurance to that. Try electricity and use it. Use a board approved electrician if required ( usually the case if you are attached in AMY way to another resident and their home..

In most cases in condos you cannot touch the exterior of the building since it does not belong to you. Add some interior lighting in LED 4000K it willinstantly improve the lighting in the space and for a heck of alot less money than adding skylights which do not increase the light at night .

Post some images to illustrate the problem. I would bet dollars to donuts your condo board will never allow you to add skylights.

Be creative. Think of another solution. Make sure you have furnishings that reflect light and interesting items on the walls.
