Seriously, I need some creative answers!--Building Buildings

One more option. As I understand it most homes in Mog have no A/C. No to mention it is a very hot place during the day. Some homes and older buildings there have really REALLY big windows. This may be to your advantage. If you have a 8" wall and two really big windows on that wall, say 2.5" long. That leaves you with an 1" on both sides and .5" in between the windows. With a net effect viewing area of 5". Also make the windows taller as well increasing the viewing depth. If your "seriously" going to do this, I would build a test building using cheap material just to see what effects lighting, large windows, removable walls/levels, ect... will have on the internal viewing.

If you need all side on that your options are limited depending on what type of buildings you are after.

You can't see into most buildings model or not, even if you do you only get to see a limited area behind the window,
provided no curtains, tinted windows or simialr are there.
Those rooms could be lit but unless you are doing a night-time scene it will look awry.

Again depending on the scale and the size of the windows it will affect how much you could even see if it was lit.
Sounds to me like you will have to compromise somewhere.

I need all four sides on the bu9ildings. On some there is a wall I don't need, but but that wouldn't help the viewr any because it's along the back wall. it's a 3 x 8 foot diorama

Ummm, maybe you could tell us what it is you DONT want to do. And from there we could advise.

But I like the building on the edge. This is how I do my dios if I want people to see the detail inside. Heres what I mean...
OUTSIDE


INSIDE

Hope this helps.

Like t3488g said thats the way I would do it.

if you put the buildings near the edge of the diorama, you can have a wall open to the side, as though you cut right through the building.

windows on the outside and maybe skylights? don't know if that will help....

lighting the interior def seems the way to go also.

maybe you can use optic fibers to light the interior. that way you can close the walls behind the buildings and the details can be seen as the interior will be lit. you can also play with the location of the fibers: fireplaces, light bulbs ETC.

I have a trouble like this myself, but I'm too lazy, I just close the windows with curtains...

That sounds like a big project! What scale?
Anyways, you could try a clear plastic sheet to go on the side (unless this is what you didnt want to do)
The piece of plastic will let the viewers see in and not be able to steal your people/objects inside, not like anyone would.

if the buildings arnt conected you could make them stackable, remove roof see 3rd floor remove 3rd floor see second floor and so on,,

or have a wall on hinges that opens to see inside ,,, maybe

Definitely sounds like a challenge.

What kind of diorama and what type of buildings?

Well if anything, there will be windows right?

Perhaps you could build them so one side of the building can be pulled away revealing the inside?

Take pictures while you're building and keep a mini-photo album alongside the diorama with pictures showing the interior?

There's always those mini cameras or like you see where they can snake down a tube with a camera on it. Get one of those and let people pretend they're like the FBI on surveillance.
