I am doing away with purpose-built corridors and instead am simply making rooms. I will separate "rooms" with a corridor-sized space.
This allows more flexibility in room design and simply in the ability to easily re-arrange the board in new patterns of rooms and "corridors".
I do not have any "corridor pieces" per se (like the painted one on the left); this should make layouts more flexible
Using this premise I made a bunch of buildings in my usual 10cm-increment pattern (10x10cm or 10x20cm rooms). Doors as usual at 3cm side by 4cm high; inset 1cm from a wall edge.
20/20 Hindsight: My experiments with my quasi-Middle Eastern terrain showed me that offsetting the doors is important to maximise the usable space in a room, and to minimize firing lanes and angles.
Thoughts: There is a 5mm lip from the corridor areas into the room. I may have to use a strip of foamboard in the corridors in order to make rooms and corridors "level"
I will probably not put any piping on the outside of the "rooms" in order that they can fit neatly together in any pattern.
I also might paint the corridor sections with metallic spray paint and then use a black wash to "grimy" it. I think metallic might be good to make it seem more "spaceship-y". Failing that grey paint will be option 2. I'll try to prep and paint some tomorrow.
The problem with the "no corridors" approach is that the rooms look like, well, separate buildings rather than part of a whole. Painting it all metallic, and using a strip of foamboard to "raise" areas between the rooms should sort this out.
I'm getting faster now - I freehand cut all the foamboard and assembled the rooms in under 2 hours while watching the Olympics, despite the fiddly flyscreen-mesh flooring slowing me up.
Total Elapsed Time: 2hrs 45 minutes
Remember, my "Quick Cheap Terrain" terrain construction challenge is this:
To produce a "unified" terrain board; that is fully modular; costs under $100 to make; and can be completed in 10-12 hours or less (a "weekend") solo.
