Bake an object with textures on both sides?

Hello, Blender noob here. I want to ask if it is possible to bake an object with textures applied to both sides of the faces. Preferably combined bake. I’m creating a moving-camera video to showcase a stationary architecture. All parts have textures on both sides, there is no thickness to the walls (see attachment). When I try to bake the double-sided parts the image texture simply comes out blank. I’m using Cycles render. Is there any way to do this, or is it not possible with double-sided faces? Any advice is greatly appreciated, many thanks!
