Posted this to Eurobricks already - but for those who don't frequent there:
I had an idea for a Lego Agents base for some time, using the 3D police station baseplate. After a failed initial project (it was too lateral to incorporate an elevator, stairs took too much room and it was corridors not rooms) I had a revisit of it, embarking upon a vertical construction. The initial design had a vehicle bay at the front hinging open like the Agents truck - the redesign instead used those panels for a "missile silo" type construction.
