Our bathroom still looks like Stalingrad, on a bad day. However, out of the ashes, like a phoenix, is rising the carcass of a new wargaming storage cupboard. This will be plastered, painted, shelved and illuminated. It's about 8' tall, by 26" square.
This will hold my gaming boards (including a new, deeper size intended to permit cavalry and tank maneuvers) and will take the surplus boxes of minis that no longer fit inside my War Cabinet. I reckon there will be room for a couple thousand more minis, which should keep me out of trouble with Mrs Bat, for 3 years, or so... after that, god knows what I'll do.
