Divided dome into three equal parts. So only the molds for one part are needed. Parts can be positioned in dome shape, but are not connected in the middle so they can be randomly scattered on a square as well if there is not enough space. Next to that this provides easy assembly since one of the three parts can be produced in one day. The next day this part can already be assembled, while the next part is being made.

Variant 1: Dome with two stairs, 90 degrees curvature. 23m2. Too big

Variant 2: Dome with two stairs, 60 degrees curvature. 17m2. 

Variant 3: Dome with two stairs, 60 degrees curvature. 17m2.  

Variant 4: Dome with two stairs, 60 degrees curvature. 15m2.  

Variant 5: Dome with one stairs, 90 degrees curvature. 19,2m2.   

 

Variant 5: Different parts place randomly on a square instead of in a dome shape.
