Indoor lighting issue on object

Hi, 
I'm having an issue where the object doesn't show properly when it's placed indoors.
Outdoors it looks fine for the most part (some weird shadows depending on position to the light source) 
Here are the examples of the issue I'm facing.

and this is how it looks outdoor:

Some of the faces turn really dark or become quite shiny even though they work when placed outdoor.
I checked my normals, tried a plain spec and bump map but it doesn't seem to do the trick? 
Does someone might know what the issue could be? 

Thanks in advance!
