Hello all, I'm in the process of converting a large industrial loft and making several bedrooms. Because all of the windows are on one side of the space, some of the rooms will not have access to an outdoor window, so I would like to incorporate windows into the walls for both light and, possibly, ventilation.

I am a renter, not owner, so I'd like to do this cheaply but beautifully if possible.

I've been considering doing 3/4 walls (the ceilings are 11.3' high) and incorporating double glazed glass (for sound insulation). This is perhaps the most aesthetic choice, although they could not be opened. Other possibilities include single/double/horizontal sliding windows, casement, or awning windows.

Has anyone ever done this or have any suggestions?

I should also say I'm in New York City, with some access to used and salvaged materials. Thanks in advance!!
