Burglar bars are pretty common here, in Indonesia. I have some on my bedroom window. However I really hate them and want to remove them.
Here is the inside for comparison
I would still like to have some sort of visual deterrent against burglary.
Note that in the photo there is also a ventilation in the middle, which I don't like either as it's a dust trap and too 'busy'. I already removed a similar smaller one by cutting through the window frame and replacing one hinged window and the ventilation area with just a pane of glass, and it's a big improvement.
In practical terms I suppose the shutters would be open most of the time, and closed when I'm not home. So it wouldn't be very ideal for them to take up a lot of space inside, because I'm going to put some low drawer units in front of the window, so it's likely that there would be 'stuff' in the way of frequently opening and closing these shutters.
OTOH if I install them on the exterior wall then I'm not sure how to secure them so they can't be opened, and also it seems like they might be a bit ugly/obtrusive if they are mostly open perpendicular (the current dimensions are roughly: 38cm - plastered brick; 4cm window frame; 68cm - hinged window unit; 41cm louvred section; ditto 68, 4, 38)
Does anyone have any suggestions about what I can do to more-or-less fix this? (note: in general windows will be closed, to keep mosquitoes out)
