This is from Antenocitis' Workshop (AW)survival line and is described on the website as "Temporary Military Command Centre" but is also described in the kit as "Military Office". Whichever handle it goes by it Makes a handy addition to the Post Apocalypse collection. 
Shown here with Canoness Veridyan for scale this is one of the easier of AW's models to build. Its got a lot of space inside due to the magic of laser etching.  There are a lot of interior details like desks, fire extinguishers, weapon racks, computers, data storage banks, maps, and clocks but none of them intrude on the playspace. Quite clever really. It allows you to cram a squad in there without acrobatics.

Its one of AW's pre-painted MDF line and the only things I painted at all were the gray desks and server cabinets and the blue water of the wall map.  Touch up the MDF snip points with Nut Brown (Reaper) and its done.  Like all the models in this line the prepaint is pretty basic but is totally playable straight out of the box and provides a nice launch point if you want a more detailed finish.  I'll likely add some weathering and graffiti to match the themes on the AZ Mart I did earlier. 
Lots of windows and the lack of actual furniture makes it easy to see which models have access.

I love the real furniture that is available for many of these buildings but there is a certain practicality in having some frequent use structures without a lot of clutter for a travel set or a pick up game.
The exterior is complete with an Air Conditioner that serves as the handle for removing the roof and a freely rotating removable radar/satellite dish. 

A great, quick to build, addition to the tabletop!
