Texturing for GreyBoxed Level

I've mapped out a level I am building but now need the walls textured. There are two main compnents. The walls for the "hallways" and the walls for the "chambers". The hallways all share the same repeating texture and the chamaber walls all share their own repeating texture.
The blue shaded areas are the hallways. The red shaded arears are the chambers. Everything else can be ingorned. I have drawings/reference images of the textures.
