I posted a WiP of this building ages back, and I've just today put the finishing touches on it. It's an industrial/arabesque building for a native settlement on Jeriko Reach.
The bulk of the building is foamcore, with inside-out GW Cities of Death building panels on the front, to provide the 40k feel. The deck is tread plate textured plasticard with small plastic rivets a mate brought back from Japan having raided the modelling shops there. The surface is textured with a mix of plaster and white glue and a variety of details added from the bits box.
