This is a multi-part kit to enable you to build a T-shaped Gothic building for wargames and small-scale dioramas. The floors are 10mm high each, so it would likely fit well with 8mm-scale, as well. The kit includes separate STL files for each part - ground floor, middle floor, roof, and roof accessories (an HVAC system and skylight). Since these are individual files, you can build a building to any height you wish by printing middle floors multiple times and assembling them with superglue. The pics above show several build ideas.
