Possible to make an objects dimensions bigger on the inside?

Say I was working on a Doctor Who TARDIS, in Roblox would it be possible for make another internal dimension on roblox where its space is inifinite compared to the normal workspace. Not using a teleport or anything like that. I want it so when you walk into the TARDIS its bigger on the inside. Is it possible? and when you look from the outside in you can see into this other space?

You could use glass or use local scripts to recreate it. With the new glass material you can see through transparent and then any partially transparent blocks behind it won't actually appear.
