3D MODEL (GLTF) OF A BUILDING FOR A CITY BUILDER GAME

GLTF format
Represents the town hall for a citybuilder game with lowpoly isometric style
I prefer a style as simple as possible with smooth surfaces without protrusions
Main colour should be #cce5ff
Dimension: (4x4) base x (2.1) height (all the space should be occupied)
Entrance door should be placed in the middle of front section
Transparency flag true

Model must have 3 separately editable aspects:

1 Basic building aspect:
a) inactive (close window and doors etc etc)
b) active (open window and doors etc etc)
c) disaster (degraded structure)

2 Above icon:
a) fire
b) collapse
c) not connected
d) no energy supply
this aspect should be complety removable

3 Selection:
(changes the coloring of all elements of the model)
a) info (dark)
b) demolition (red)
this aspect should be complety removable

In total I need about 100 such templates to complete my project.
For this reason, I ask you not to apply if you cannot guarantee the subsequent availability to make all the models.
