As I started trying to stand the building up to glue it together I ran into a challenge - it wouldn't stay standing up. I messed around with it for a few minutes before this idea came to me.

I just rolled up a few pieces of yellow poster tack and it stood up like a champ.


Here is one of my Chaos Space Marines for scale.

Here is an interior shot of the building. I still need to cut out the floors.

Next time I should have pictures of the structure glued together with the floors in place.
