Very nice looking mod.

Walls not laying flush on top of existing door frames.
Not sure you can do much against existing greenhouse frames but metal frames should be able to align better.

Adjust support on ceiling 1 to remove double support effect when ceilings placed together.
Support on stairs would need altering to match too. As would Sloped Roof 1

Possible to have rivets go through the glass rather than just a rivet head on top ?

If not. Remove rivets to match Foundations look, or add rivets to foundation too.

Adjust round supports on Ceiling 3 4 and 5. Use half cylinders on the outside edges to give a solid cylinder effect when 2 ceilings placed together.
Same for Wall 1 and wall 2

If you do adjust wall 1 and 2. you may need to alter the diameter of cylinder to match thickness of other walls (or make a duplicate of walls 1 and 2 and make those half cylinders)

Possible to adjust (or add) snap points to Foundations so ceilings can snap cleanly to them when needed ?

Ceiling 1 maybe in need of cropping. Only noticed this when left/right roof was placed. So could be those causing the effect.

Sloped Roof 1 needs work. Walls Sticking through bottom edge.
May wish to consider removing the outer edge of roof to doesn't stick though walls
